Ninghai county administrative examination and approval management office (hereinafter referred to as Ninghai county audit management office), formerly known as Ninghai county people’s government accreditation center (renamed Ninghai county administrative service center in December 2003), was formally established in April 2008. Since its establishment, Ninghai County Audit Office has adhered to the working philosophy of "satisfying the people is our pursuit", adhering to the service tenet of "convenience, standardization, high efficiency and honesty", based on the service brand of "heart-to-hand connection and unlimited service", taking the convenience of investors and serving the masses of enterprises as the value orientation, and implementing the operation mode of centralized management and window office. At present, the building area of the administrative service hall is 22,050 square meters, and there are 246 staff members, with an annual average of more than 500,000 pieces. It has successively won the honorary titles of Zhejiang Advanced Grass-roots Party Organization, Zhejiang Outstanding Youth Civilization, Zhejiang Civilized Unit, and National Women’s Civilized Post, and has been called the "government supermarket" in Ninghai.

As an important carrier of service-oriented government construction, in recent years, according to the requirements of the "streamline administration, delegate power, strengthen regulation and improve services" reform of the central government and the "Four Clears and One Net" reform of Zhejiang Province, Ninghai County Audit and Management Office has been innovative and brave in exploration, and has effectively improved the efficiency of examination and approval services through measures such as process reengineering, simulated examination and approval, dynamic management, filling in gaps and joint examination and approval. On January 16th, 2017, since Zhejiang Province put forward the reform of "running at most once", Ninghai County Audit and Management Office closely followed the pulse of the times, quickly completed the reform of "accepting and integrating services in one window" with the spirit of nailing nails, announced the power items of "running at most once" administrative examination and approval, actively created an upgraded version of the reform of administrative examination and approval system, and promoted the implementation of the reform of "running at most once" to get the reform bonus as soon as possible. On March 13th, 2017, Ninghai County Audit Office’s advanced experience, Ninghai County’s Creation of "Ten Running Methods" and Accelerating the Reform of "Running Once at Most", was affirmed by Mayor Qiu Dongyao of Ningbo City, and then published in a special issue in the General Office of Zhejiang Provincial People’s Government, and reported to the State Council. Media such as Ningbo Daily, Ningbo News and Zhejiang Daily have reported advanced practices many times.

First, innovate and continue to deepen the reform of the administrative examination and approval system

1 to promote the reform of administrative examination and approval functions. Since 2008, the Audit Office of Ninghai County has carried out the reform of administrative examination and approval functions with the main goal of "two centralization and two in place", that is, the examination and approval functions of functional departments are centralized in one department, and the administrative examination and approval department is centralized in the examination and approval service hall, and the examination and approval projects of functional departments are centralized in the administrative service center window, and the approval authorization of functional departments to the person in charge of the window is in place. All departments have set up or listed administrative examination and approval departments, and entered the window of the administrative service hall in an organizational system. All the section chiefs and deputy section chiefs have arrived at their posts, and the authorization is in place, which has achieved the purpose of one leader in charge, one pen signing and approving, one window opening to the outside world and one-stop service, and completely solved the problems of accepting at both ends and the masses running at both ends. At present, there are 34 departmental windows in Ninghai County Administrative Service Center, 20 independent windows, 11 comprehensive windows and 3 sub-centers.

2. Promote the construction of Ninghai platform of government service network. In March, 2014, according to the unified deployment of Zhejiang provincial government, the construction of "four clean sheets and one net" was launched in an all-round way (list of government power, negative list of enterprise investment, list of financial special funds management, list of government responsibilities, Ninghai platform of Zhejiang government service network), and Ninghai County Audit Management Office was responsible for sorting out the "three and a half items" of audit power list (administrative license, administrative confirmation, audit report and annual inspection, filing and other approval rights in other administrative powers). At present, a total of 1016 items of "three and a half" examination and approval power have been determined in the county. Except for 16 items that meet the requirements and are not allowed to enter the administrative service hall, all 1000 items have entered the window, with a occupancy rate of 100%. Of the 1,000 "three-and-a-half" examination and approval power items stationed, except for 13 authorizations, 987 authorizations were in place, and the on-site handling rate reached 98.7%. Dynamically manage the speed-up of administrative examination and approval in each window, and "force" each window to improve service efficiency and speed up examination and approval. At present, the total promised processing advance rate of the administrative service hall is 87.47%, and the actual processing advance rate remains above 98%.

3. Promote the reform of "one-window acceptance and integrated service". Since 2017, the Audit Office of Ninghai County has actively played the role of the main channel of the administrative service center, actively promoted the reform of "running at most once" and "accepting and integrating services in one window", rearranged the existing windows of the administrative service center according to the principles of "doing one thing in one window" and "relatively separating the right to accept and the right to review and decide", implemented the comprehensive acceptance staff, and implemented "one person with multiple posts and multiple functions in one post". Integrate the original layout with a single department as the window into six categories of comprehensive service processing areas, including capital construction projects, commercial registration, real estate registration, public security services, public security exit-entry management, and social and people’s livelihood affairs. Enterprises can handle multi-departmental matters without running errands to and from multiple department windows. For example, real estate registration originally needed to run errands in the three departments of housing management, finance and taxation, and real estate. Now, you only need to run a window of ownership registration to complete the examination and approval at one time, which will boost the reform goal of "running at most once".

4. Promote postal express service in the window. The introduction of postal courier companies into the window of the administrative service center, for matters that cannot be declared online, on the basis of voluntary principle, entrusts postal courier companies to carry out the express delivery service of licenses. Applicants only need to sign a delivery agreement and fill out a delivery application, and the postal courier companies can deliver the licenses to the door, "turning the masses into express delivery". At the same time, the qualified departments are encouraged to subsidize the reduction or preferential treatment of license express delivery fees in the form of "government pays the bill". Up to now, 15,157 pieces of accounting qualification certificates and entry and exit certificates have been sent by postal courier company. At the same time, we will actively create five special services, such as "no holiday" service, "nanny-style" agency, "zero distance" site, "through-train" express service and "no lunch break" work.

Two, self revolution, strictly regulate the administrative examination and approval service process.

1. Standardize the industry joint examination and approval standards. We will fully implement the joint examination and approval standards for 16 industries, including bathing, maintenance and management of Class I motor vehicles, transportation, hotels, small and medium-sized restaurants, culture and entertainment, overseas satellite TV, large supermarkets, film screening, swimming pools, automobile beauty, agriculture (fishing) music, hotels, hairdressers, cafes and foot baths, with the lead window taking the lead according to the mode of "one window for acceptance, internal circulation and one window for delivery". For example, in the homestay industry, it used to be necessary to run five departmental windows, such as fire protection, public security, environmental protection, health and family planning, and market supervision. Now, you only need to run one departmental window of public security to get all the documents, which effectively realizes the reform goal of "running at most once".

2. Standardize regional joint examination and approval standards. Innovative implementation of cross-project, cross-departmental and cross-plot linkage approval mode, the "Implementation Measures for Regional Joint Approval of Investment Projects in Ninghai County (Trial)" was introduced, and the province took the lead in piloting regional joint approval of investment projects. All the investment projects in the industrial base of "Two Zones and Eight Parks" will be regarded as one project, and the pre-approval procedures such as planning environmental impact assessment, soil and water conservation plan and industrial planning of the whole region will be worked out in a "packaged" way in advance. For the designated projects settled in the region, the procedures for filing will be implemented first, which will simplify the approval procedures for individual projects. Taking the industrial park as a unit, the planning indicators such as greening rate, floor area ratio, building density, parking spaces and civil air defense facilities are planned as a whole, and the "single check" is changed into "regional overall check", which breaks through the limitation of land use, improves the yield per mu and achieves overall coordination and balance. Effectively reduce the examination and approval links and reduce the number of runs.

3. Standardize the preconditions for administrative examination and approval. In order to solve the problem of "difficult and troublesome work", in 2015, Ninghai County Audit and Management Office carried out a special clean-up work on certification materials in the field of people’s livelihood, and found out 86 certificates required, and urged all departments to cancel 23 illegal and unreasonable certificates and temporarily keep 63 items. In the special supervision activity of finding out "difficult matters for grassroots people to handle affairs", it was affirmed by Mao Linsheng, party secretary and deputy director of the Standing Committee of Zhejiang Provincial People’s Congress. In 2016, Ninghai County Audit Office cleaned up the pre-condition materials of 1016 examination and approval power matters in the county, and cancelled 29 pre-intermediary services of 158 administrative examination and approval, accounting for 18.35%; 159 pre-condition materials such as certificates and seals, 77 items were cancelled, accounting for 48.43%; 55 Pre-condition material cover clauses, 32 items were cancelled, accounting for 58.18%. Reduce the phenomenon of repeated provision and repeated provision of materials, effectively solve the strange phenomenon of "approval for approval", reduce the burden on enterprises and reduce the number of errands.

4. Standardize the operation mechanism of administrative examination and approval. Give full play to the gathering function of the administrative service center, innovate the examination and approval operation mechanism, implement the examination and approval mode of "one acceptance, copying and reporting, joint examination and completion within a time limit", establish and improve the joint examination and approval mechanism of investment projects, and establish the "6+1" consultation, "8+X" joint examination and hierarchical coordination mechanism. In the process of investment project examination and approval service, straighten out the business circulation relationship, and complete the project examination and approval in a "one-time" and "one-stop" way through joint meetings, joint reconnaissance, joint map examination and departmental linkage, so as to improve the examination and approval efficiency.

Third, follow the trend and boldly use "Internet+government services"

1 to promote the construction of a unified administrative power operation system. In March 2014, the construction of Ninghai platform of Zhejiang government service network was started. On June 25 of the same year, the platform was displayed to the public and became a collection platform carrying four lists and public service lists. In June 2015, the unified administrative power operation system of Ninghai platform was officially put into operation online, and all the "three and a half" administrative examination and approval power items were accepted online. In 2016, the extension of Ninghai Platform to townships (streets) and villages (communities) was completed, and 118 items of power in townships (streets) and 49 items in villages (communities) were pushed. A three-level linkage network approval platform connecting 18 township (street) convenience service centers, 363 village-level convenience service centers and 28 community service centers will be built, and a cross-level background approval circulation mechanism will be established, so that enterprises can realize "running at most once" at their doorstep.

2. Promote the superposition effect of "internet plus" approval. Since 2017, 864 items of "running at most once" in 33 administrative examination and approval functional departments in the county have been sorted out, accounting for 85.04% of the total, and the goal of reaching 80% by the end of the year proposed by the provincial government has been completed ahead of schedule. There are five ways to achieve "running at most once", namely: 151 items to be done immediately, accounting for 17.48%; Window declaration, 346 items of express delivery, accounting for 40.05%; Online declaration, pre-trial, window verification and picking up 354 items, accounting for 40.97%; The whole process of online bidding, express delivery of 6 items, accounting for 0.69%; The whole process of online bidding, online pick-up items 7, accounting for 0.81%. According to local conditions, the pilot will be carried out first, and 12 towns and villages, such as central village, island village, Gaoshan village and satellite city, will be selected to build demonstration sites, and terminals will be added to build a "full coverage" government service system combining online and offline. Combined with "online intermediary supermarket", online joint examination of construction drawings, mobile phone approval, etc., give full play to the multiple effect of administrative examination and approval. Do your best to let the masses run less and run more information.

3. Promote the construction of online approval and supervision platform for investment projects. Relying on Ninghai platform of Zhejiang government service network, a unified framework, norms and standards, vertical and horizontal linkage investment project approval and supervision platform was developed, which was officially put into use on August 22, 2016. All matters that need the signature and seal of government departments in the whole process of investment projects from registration and coding to completion acceptance were included in the platform operation, so as to realize the smooth operation of the whole network of the platform. When an investment project is approved, it is uniformly coded by the window of the development and reform department as the unique identity of the whole project construction cycle. All investment projects are uniformly approved on the online approval and supervision platform of investment projects, and subsequent approval departments identify relevant approval information by project codes, effectively breaking the departmental information barrier and avoiding the phenomenon that project owners repeatedly provide and repeatedly provide pre-approval results.

4. Promote the construction of video workstations in virtual halls. Upgrade WeChat WeChat official account, purchase a video terminal, and create the first video workstation for consultation and consultation in the virtual hall in the province. For the popular matters of investment projects, industrial and commercial registration and other enterprises, by clicking on the matters to be handled in the virtual hall, the video will automatically connect to the approval window, and the window staff will provide remote guidance to solve problems, so as to build a service system in which the project owner and the approver can seamlessly connect, and reduce the number of errands for investment projects. At the same time, the WeChat pre-approval service is implemented. The enterprise masses download the form on WeChat WeChat official account and upload the approval materials through WeChat. The window staff pre-examine the materials provided by the applicant, and complete the approval if the materials meet the requirements. The enterprise masses can lead the relevant licenses on the spot as long as they run the window once to check the original.

Four, the courage to fight, explore the development path of administrative examination and approval services.

1. Reengineering the investment project approval process. In order to solve the problems of many preconditions, many examination links, many examination departments, long examination and approval time, and "difficult and troublesome examination and approval". The Implementation Measures for Optimizing the Examination and Approval Process of Investment Projects in Ninghai County was promulgated, and the examination and approval services within the jurisdiction of investment projects were reduced from 42 to 24, and the cumulative time for examination and approval was reduced to 40 days. In view of the phenomenon that small and micro projects in rural areas have less investment but the same number of approval links, it is decided to change the village-level projects that do not involve government funds from the approval system to the filing system, that is, from the original three links of proposal approval, feasibility study report approval and preliminary design approval to the filing one link for approval.

2. Simulated examination and approval of innovative investment projects. The Implementation Opinions on Simulated Examination and Approval of Investment Projects in Ninghai County was issued. On the basis of consultation and demonstration on the feasibility construction of investment projects, simulated examination and approval were carried out for investment projects with mature conditions in the early stage, and the land was deemed to have been obtained. After the planning scheme was determined, the examination and approval methods such as pre-examination, pre-examination and pre-intervention were implemented to speed up the examination and approval. In the same examination and approval process, pre-examination and pre-investigation shall be carried out to separate the technical elements from the procedural elements. If the technical elements basically meet the examination and approval requirements, a simulated examination and approval opinion shall be issued; In different examination and approval links, advance examination and approval shall be implemented, disrupting the pre-approval methods in the inherent examination and approval procedures, and some pre-approval shall not be regarded as the necessary conditions for post-approval; In the whole examination and approval process, we should intervene in advance, and after completing the pre-examination, budget review, planning review and other related links, we should intervene in advance in bidding to realize the early implementation of one or several monomers.

3. Implement efficient examination and approval of industrial projects. From the preparation of planning conditions before land listing, the preparation of land transfer scheme to the handling of construction permit, the methods of "early intervention" and "parallel approval" are adopted for enterprises’ investment intention projects, and the project-related simulation approval and land bidding, auction and hanging are carried out simultaneously, and all approval processes are completed in 94 working days, including 29 working days for administrative approval and 65 working days for intermediary service, creating a full flow chart of 100-day efficient approval for industrial social investment projects.

4. Promote joint measurement and joint completion acceptance of industrial investment projects. The "Notice on Implementing Joint Surveying and Mapping for Construction Project Completion" was issued, and the "Three Surveying in One" system was implemented for investment projects. The Implementation Plan for Joint Acceptance of Industrial Social Investment Projects in Ninghai County (Trial) was issued, and the operation method of combining pre-test with joint acceptance was implemented.

5. Innovate the linkage mechanism of intermediary services. Establish "pre-intermediary service area involving investment project approval" and "online service supermarket involving pre-intermediary approval", and publish intermediary service catalogue. Research and develop intermediary service monitoring system, and integrate intermediary service into electronic monitoring system to implement "dynamic management". Strengthen the communication and contact between examination and approval departments, intermediaries and project owners, form a seamless connection between examination and approval departments, intermediaries and owners, and form a tripartite linkage mechanism. The advanced practices have been affirmed by Vice Governor Zhu Congjiu.

6. Carry out agency services for investment projects. Establish a county agency service center for the whole process of investment projects, set up an agency studio, implement full-time agents, establish a county, township (street) two-level agency service system, formulate the "Detailed Rules for the Implementation of Agency Service for the Whole Process of Investment Project Approval in Ninghai County", refine the agency and assistance mechanism, determine a special person to be responsible for tracking the progress of project approval, hold regular work meetings, supervise the progress of approval every month, and seamlessly connect investment projects by means of departmental linkage and on-site centralized service. Ensure that "information is submitted in time, approval is approved in time, and approval is not divorced", provide "shop assistant" service for administrative approval of investment projects, and speed up the construction of investment projects.

Fifth, help each other in the same boat and get through the "last mile" of serving the masses of enterprises

1. Introduce OSM site management standardization. The OSM site management system of Hong Kong Site Management Institute was introduced, and the management standards of personnel, space, articles, equipment, information and waste were formulated, and standardized management was implemented, so that the overall image of the window was obviously improved and the working environment of the masses was obviously improved.

2. Implement the third-party telephone return visit system. Entrust the third party of telecom to pay a return visit to the examination and approval service results, publish them in the monthly inspection report in time, and give feedback and suggestions. At the same time, we will increase the assessment of the satisfaction of the masses, and include the assessment of the satisfaction of the masses in the monthly and annual assessment of the window. At present, the satisfaction rate of telephone return visits is over 99.6%.

3. Strengthen window management inspection inspectors. Through daily supervision, weekly inspection, monthly assessment and annual assessment, the management assessment of staff and department windows is scientifically set up and implemented. Take the initiative to listen to the opinions and suggestions of all parties through issuing service object evaluation forms, in-depth investigation of enterprises and grassroots units. By hiring supervisors of morals, consulting opinions regularly, and widely accepting social supervision. Through the whole process supervision of electronic monitoring system, problems can be found and corrected in time, and the management of administrative service center can be strengthened from all channels, in an all-round and three-dimensional way.

4. Strengthen the evaluation of window departments. A series of institutional measures, such as the Implementation Measures for the Service Assessment of Ninghai County Administrative Service Center, the Interim Measures for Investigating the Fault Responsibility of Window Staff, and the Service Star Appraisal Measures, were issued, and the administrative examination and approval service of window departments was included in the work target management assessment, with an assessment score of 3 points, which effectively strengthened the window management.

　　　　　　 CCTV News:The Ministry of Transport recently issued the "Guidelines for the Prevention and Control of COVID-19 Epidemic in Passenger Stations and Means of Transportation in Spring Festival travel rush in 2021", focusing on seven areas such as road passenger transport, urban public buses and trams, urban rail transit and waterway passenger transport, and formulating detailed epidemic prevention and control measures from five aspects such as disinfection, ventilation, transportation organization, personnel protection and publicity.

　　　　　　 In view of the characteristics of increased personnel flow and increased risk of epidemic spread during the period of Spring Festival travel rush, the Spring Festival travel rush Guide improved the prevention and control standards, made prevention and control by districts and levels, and comprehensively improved and strengthened prevention and control measures. During the period of Spring Festival travel rush, the disinfection frequency of passenger stations and means of transport should be appropriately increased. Strengthen the registration of passenger information, and fully implement the registration of real-name tickets for passengers on Class I and Class II passenger lines and inter-provincial and inter-city chartered passengers. Check the health code of passengers entering the road and waterway passenger station comprehensively, and provide services such as checking the health code on behalf of the elderly, children and other passengers who can’t use or don’t have smart phones, and assisting in filling in information. Temporary observation areas should be set up for 10 or more inter-provincial passenger vehicles and passenger ships, and the passenger load factors in high, medium and low-risk areas should not exceed 50%, 70% and 90% respectively. At the same time, strengthen the health monitoring and protection of employees, guide passengers to travel in the wrong peak, and take protective measures such as wearing masks, hand hygiene and "one-meter line" during various public transport.

CCTV News:This year is the Year of the Rabbit, and the fate of "Rabbit" and China in exploring space is really not shallow. Speaking of China’s lunar exploration, in the Chang ‘e project, the Yutu lunar rover brought us too many surprises.

On the occasion of the Lunar Year of the Rabbit, China’s lunar exploration space rabbit released its official Chinese and English names, namely "Rabbit Star" in Chinese and "To star" in English. "Rabbit Star" means "Jade Rabbit patrols the moon and sails the Milky Way". The lunar rover No.3 and No.4 in China is named "Jade Rabbit", and the name of "Rabbit Star" expresses its space characteristics and initial mission.

　　　　　　 The English name "To star" means that our journey is a sea of stars. The design of "Rabbit Star" itself embodies the integration of traditional culture and space science and technology, entrusts the Chinese nation’s dream of exploring the moon for thousands of years, and expresses the lofty vision of China’s space flight to the deep space of the universe in the new era.

On the occasion of the Spring Festival in the Year of the Rabbit, the Yutu-2 lunar rover in China’s lunar exploration project sent back the latest photographic works from the moon 380,000 kilometers away and sent a New Year greeting.

CCTV reporter Li Ning:During the Chinese New Year, there will still be many people sticking to their jobs, including the Yutu-2 lunar rover, which is conducting (scientific) exploration on the back of the moon 380,000 kilometers away. I am now in the operation control and scientific operation center of the ground application system of the National Astronomical Observatory, and this image from the moon seen in the picture is the latest return of Yutu II lunar rover. Above, we can see that the topography of the moon is bumpy. This is the rut mark that Yutu-2 has traveled. It climbed a hill in this area, and then it began to enter a relatively gentle road, and you can see very clear rut marks.

CCTV reporter Li Ning:The rut mark is next to an impact crater. How does it avoid it in this process? How to design a route for it?

Li Chunlai, deputy chief designer of the third phase of the lunar exploration project:The walking route of Yutu-2 is to get the position in front with its own navigation camera, and we have to restore and analyze a terrain before we can decide where it goes. It has a climbing ability of 20 to 30 degrees, but we find that the soil on the moon is loose, so we won’t walk in this extreme condition, and we also hope that its loss will be smaller and safer.

At present, Yutu-2 is located in the north-west direction of the landing site, with a linear distance of about 800 meters. The state of the lunar rover and the scientific load on it is all normal. During the Spring Festival of the Year of the Rabbit, researchers from the National Astronomical Observatory will work overtime with Yutu II to continue the lunar exploration.

Li Chunlai, deputy chief designer of the third phase of the lunar exploration project:We will also spend the New Year with Yutu II, and wish Yutu II great success in the new year.

Ouyang Ziyuan, Academician of Chinese Academy of Sciences, First Chief Scientist of Lunar Exploration Project;I wish you all good luck in the Year of the Rabbit and all the best. The Jade Rabbit in the Moon Palace will make greater achievements and make contributions to our lunar explorers.

Ground application system team of lunar exploration project:Jade Rabbit will accompany you in the Year of the Rabbit, and I wish you all the best.

Produce/browse the business

Author/Xue Xiang

Recently, two real-time retail data have attracted the attention of a glance at business.

One is that in a recent sharing, Xu Lingna, general manager of over the rainbow Lingzhi Mathematics Department, revealed that online sales in over the rainbow have soared in the past three years, accounting for nearly 30% of the total, while 20% of online sales in over the rainbow actually came from the time when stores closed from 10 pm to 9 am the next day. That is to say, the online instant retail in over the rainbow not only transferred the offline sales to online, but also obtained additional orders.

On the other hand, according to the data of China Chain Store & Franchise Association, in the past year, 67.2% of convenience store visitors decreased compared with last year, but in the case of declining passenger flow, the overall sales of convenience stores changed in the opposite direction. In 2022, the total sales of 64.1% convenience store enterprises still increased year-on-year, one of the main reasons was that they did instant retailing.

Actually,Both over the rainbow and convenience stores are the first batch of instant retail players, and they are pathfinders who have made achievements. Nowadays, more and more platforms and businesses begin to enter this track, and the industry has more and more different views on it.

dispute

Everything is divided into two parts, and the growth of any new thing is accompanied by controversy, and instant retailing is no exception.

After communicating with a number of retail industry practitioners, a glance at the business found that merchants’ worries about instant retailing are mainly reflected in the impact of mature retailers on husband and wife department stores after entering the network, as well as the order distribution of ordinary stores and pre-warehouses. The first batch of instant retail stores have made profits, so it is time to clarify the causes of the dispute and seek solutions.

Online retailing is the true mapping of offline commerce, and the competition between Shangchao convenience store and couples grocery store will certainly exist for a long time.

Consumers are used to online consumption, and this habit is irreversible. As the data at the beginning of the article shows, in the past year, the passenger flow of offline physical stores has been affected, and couples department stores are no exception. When supermarkets, convenience stores and other mature formats, relying on their own capital, technology and traffic advantages, transform to online in advance, the pressure on mom-and-pop stores is even greater.

Indeed, in front of offline mature retailers such as supermarkets, convenience stores, collection stores and discount stores, mom-and-pop stores will naturally be considered weak. At the same time, take-away food has a wider range of radiation, and stores in different blocks are likely to be placed on the same plane for competition. Therefore, it is easy to think that the online increase of supermarkets and convenience stores is obtained by seizing the market share of mom-and-pop stores.

This view has some truth, but obviously underestimates the vitality of the mom-and-pop shop.

First, instant retailing, no matter how to expand its business scope, will not let small stores compete with national brands, which is a local format after all. As long as it belongs to local retail, there will always be a place for couples’ shops, and no one knows the local ecology better than them.

Second, mature retailers often come into contact with new models more quickly, and competition will return to the same starting line after couples’ department stores join instant retailing. With the help of various online business tools, community stores can gain insight into demand faster and stock up flexibly.

Regarding the competition between ordinary stores and front warehouses, we believe that the two formats are dislocation competition and can coexist completely.

Whether it is an "amphibious" store or an online store, it is formed under the impetus of the outbreak of demand and the prosperity of supply. The core of instant retailing is local supply, and consumers will feel convenient only if the coverage rate of businesses in a certain area reaches a certain standard. Taking Meituan as an example, before the launch of new supply projects, some merchants started the pre-warehouse business spontaneously.

Besides,In a glance at the business, this kind of "pre-warehouse" and offline-oriented community stores, although there is competition, are more of a misplaced competitive relationship.

For these small shops, the front warehouse does not have the offline sales function, and many online orders of small shops are the increment brought by expanding the business radius, which does not affect the offline business. Consumers who used to visit small stores may also increase their shopping frequency because of the "home delivery" service. For community stores, the setting of online "starting price" will also increase the unit price of customers.

No matter in terms of product selection, service mode or customer acquisition method, the husband and wife shop can well adapt to the local people’s life and consumption habits, and can also be connected to the community group purchase to become a "group leader", flexibly expanding more convenient services, including making breakfast, receiving express delivery, printing faxes, weighing, and even walking dogs instead of surrounding residents.

value

The above problems mostly point to the possible competition between instant retailers. A glance at the business believes that online and offline integration is an inevitable trend. Instead of worrying about competition and opposition, businesses should study how to adapt to changes and give full play to their comparative advantages.

At present, instant retailing originates from the elimination of instant consumer demand. Thanks to the development of physical retailing in China, both the supply and demand sides are in the stage of increasing and expanding. As the report of the Ministry of Commerce recently predicted, instant retailing will cover more application scenarios.

First of all, the epidemic, e-commerce, pre-warehouse, and community group buying have made consumers more lazy. Changes in consumption habits have forced physical retail to enter the network, making home delivery a retail standard.

Secondly,The theme of retail has always been to reduce costs, improve efficiency and make consumers get more convenient services. The essence of the Internet platform is connectivity, which can match transactions by reducing the information gap. This is the case with the most prosperous online e-commerce in the past two decades. The traditional e-commerce supported by social logistics has become the Red Sea, and instant retailing is a new opportunity for physical stores, the main body that failed to profit from e-commerce in the past.

Finally, the first wave of merchants who have joined instant retailing have begun to get dividends, and the speed of merchants accessing the network will be faster and faster. Taking convenience stores as an example, the take-out ratio of the head stores of Henan Yuelai Yuexi can reach about 30%, which probably brings about a 50% increase. Instant retail orders for fresh food in Wuhan Today convenience store increased by 90%. At first, online orders were only 2,000+a month, and now there are more than 10,000 orders a month.

Wu Teng, vice president of Hebei 36524 convenience store, told a typical example. There are seven stores similar to them on a street in Shijiazhuang, and the latest order they took over was placed 30 meters across the road, and the delivery distance was no more than 100 meters. They bought iced drinks and snacks. If they don’t provide instant retail, this order will definitely miss them.

Under such circumstances, only doing a single channel has become a disadvantage. Even for large-scale chain retail enterprises, the outlets are dense enough, but it is inconvenient for consumers to come out or even want to come out, so they can only watch the orders fly away.

Therefore, a glance at the business believes that,For businesses that have set foot on instant retail ships, we should continue to adhere to and operate for a long time. For businesses that have not started to do instant retail online, we should shelve the debate and actively transform with reference to the operating experience of the first wave of online businesses.Moreover, from the commercial point of view, joining at this time also has advantages that the first wave of mature retailers do not have.

On the one hand, after years of development, the instant retail platform has developed a perfect digital system, which can enable small-scale community stores and small supermarkets to quickly access the network at low cost, saving a lot of technical investment;

On the other hand, the change of consumer habits means that the early stage of consumer education has ended. At this time, going online can not only expand the coverage of small stores, but also reduce the marginal cost of rent by adding new orders.

In addition, local supply is the foundation of real-time retail, and the key for physical stores to do real-time retail is to keep up with the real-time needs of local consumers. This is also a huge advantage for the mom-and-pop shop, which is already in the community and familiar with the surrounding environment.

Finally, let’s look at a set of news:

This year’s No.1 Document of the Central Committee mentioned instant retailing for the first time, pointing out that "the construction of county commercial system should be comprehensively promoted. Accelerate the improvement of county and rural e-commerce and express logistics distribution systems, build county-level collection and distribution centers, promote the integration of rural passenger and postal services, and vigorously develop new models such as joint distribution and instant retail. "

According to the estimation of China Chain Store & Franchise Association, from 2020 to 2021, the annual growth rate of instant retail will basically remain at 80% to 100%.

Obviously, the development of instant retailing is the general trend. Although there is some controversy, everyone is more worried about the possible uncertainty.

Throughout the history of human development, there are many uncertainties, but in the history of instant retailing, at least the achievements of the first wave of merchants such as supermarkets and convenience stores are certain, and the operation mode is also certain, so is the widening of the operating radius of mom-and-pop stores.

A glance at the business believes that the essence of instant retail is retail, so it is still a long-running business, and we can’t just look at short-term disputes. As long as merchants are good at tapping the unmet needs of offline and traditional e-commerce, as long as they turn traffic thinking into cost thinking, serve residents well in a limited radius and ponder over details, they can see more certainty in the instant retail field.

I drive a Camry (parameter picture) twin engine, and there are three shortcomings that are unacceptable, and it is really expensive to change the battery. I advise people who want to buy a hybrid car to think twice, otherwise it will be too late to regret it!

The automobile industry is experiencing a great change that has never happened in a hundred years, and it has become an inevitable trend to develop new energy vehicles.

Plug-in hybrid vehicles and pure electric vehicles are the main models in the future, while hybrid electric vehicles will be eliminated in the future!

This is the real reason why Corolla twin-engine, Camry twin-engine, CR-V and other hybrid vehicles can’t be on the "green card"!

However, at present, Toyota and Honda-based hybrid electric vehicles have achieved high sales, and many consumers are waiting to see and want to buy a hybrid electric vehicle.

So is the current hybrid car worth buying? What are the shortcomings?

Next, I will analyze the advantages and disadvantages of the hybrid car and how much it costs to replace the battery, hoping to give some valuable information to readers who want to buy a hybrid car.

What’s the difference between Toyota THS, Honda i-MMD and BYD DM-i? Did DM-i learn from Honda i-MMD?

We want to know whether the hybrid car is worth buying. First, we need to understand the working principle of the hybrid car, so as to understand the advantages and disadvantages of the hybrid car!

At present, Toyota THS and Honda i-MMD hybrid systems are the main hybrid vehicles. Although both of them are hybrid systems, their working principles are obviously different.

The working principles of Honda i-MMD and BYD DM-i are more similar, so Honda CR-V has two hybrid models, one is a hybrid electric vehicle, and the other is a plug-in hybrid vehicle.

Honda’s i-MMD oil-electric hybrid uses clutches to realize three driving modes.

The first pure electric modeWhen the engine does not work, the clutch of the power separation device is disconnected, the vehicle is directly driven by the motor, and the power battery provides the power source. At this time, the working principle is the same as that of a pure electric vehicle.

The second hybrid modeThe vehicle is still directly driven by the driving motor, and the engine works normally. At this time, the power clutch is disconnected, and the engine is only responsible for driving the motor to generate electricity, and does not directly participate in the driving.

At this time, the working mode is more like an extended-range electric vehicle, and the driving principle is the same as that of an extended-range electric vehicle in Li ONE, so the engine always runs at the highest efficiency and the fuel economy is very high.

The third engine direct drive modeThe engine is working, the power clutch is closed, and the driver controls the power output of the engine through the throttle. At this time, the working mode is the same as that of the fuel vehicle.

When the vehicle needs to overtake and speed up, the motor intervenes to drive, and the auxiliary engine drives the vehicle together. At this time, the vehicle has the strongest power.

The above three driving modes are basically consistent with the working principle of BYD DM-i. Some people think that DM-I borrowed the working principle of i-MMD, but as early as 2008, BYD introduced F3DM, which is the world’s first mass-produced dual-mode vehicle.

The working principle of BYD F3DM is not the same as that of the familiar Tang DM, but the same as that of the Song Plus DM-I. As for why it was not accepted by the market at that time, the main reason was that the engine carried by the F3DM was too poor.

The DM engine is equipped with a 1.0L three-cylinder engine, and its power output is not strong. In the hybrid mode, the power output is insufficient, which makes it impossible to play the advantages of the hybrid mode, so it was eliminated by the market.

In 2012, Honda released the i-MMD hybrid technology, and in 2013, it officially launched the production model, so it was not DM-i that borrowed from i-MMD.

Toyota THS has developed into THS II, which is much better than the previous generation and can be divided into two driving modes.

The first pure electric modeThe engine does not participate in the work and will not start, and the vehicle is driven entirely by the motor, which is the first difference from Honda i-MMD.

However, the pure electric mode of Toyota THS II has a disadvantage, taking Camry twin engines as an example.

Because the battery is only 1.3kwh, it can only be turned on when the power is sufficient, and the pure electric mode can only travel about 2KM, and the speed cannot exceed 50km/h, otherwise it will directly exit the pure electric mode.

It can be said that the pure electric mode of Camry dual-engine is relatively small, but the application scenarios are still relatively rich. For example, the pure electric mode can be enabled when moving cars in short distances, congested roads and queuing, which can avoid the engine idling for a long time.

On the one hand, it can avoid carbon deposition caused by long idle speed of the engine, on the other hand, the engine stops working to achieve the purpose of saving fuel.

The second hybrid mode, due to the working principle of Toyota THS II, is divided into two working states in hybrid mode.

The first working stateDuring normal driving, when the Toyota THS II exits the pure electric mode, the vehicle directly enters the hybrid mode, and the engine and motor drive the vehicle at the same time.

When the power output by the engine is greater than the driving force required by the vehicle, the engine will drive the generator to charge the battery.

The second working stateWhen speeding up overtaking, long-distance climbing and high-speed driving, the engine and motor will still drive the vehicle together, but the engine will use all the power to drive the vehicle and the generator will stop charging the battery.

The power battery also uses all the electricity for motor-driven vehicles, at which time the vehicle has the strongest power. Because Toyota THS II has no engine direct drive mode, this is the second difference from Honda i-MMD.

The first disadvantage, the characteristics of the hybrid working mode of oil and electricity, can’t be green, can’t be exempted from purchase tax, and the price is expensive, saving fuel but not saving money.

Whether Toyota’s THS II or Honda’s i-MMD, the energy for driving vehicles in pure electric mode still comes from fuel.

The cruising range of pure electricity is too short, and the motor is only an auxiliary function. The main driving mode is the engine.

Therefore, hybrid electric vehicles are not new energy vehicles, so they can’t get a green license, and they can’t enjoy the same exemption from purchase tax as plug-in hybrid vehicles.

Take Camry twin engines as an example. The starting price is 219,800 yuan, 40,000 yuan more than the fuel version of the entry-level Camry, and 20,000 yuan more than the fuel version of the Camry with the same configuration.

Imagine that the hybrid of oil and electricity does save fuel, but can it save fuel and money?

I’ll work out an account for you.

With the same configuration, the fuel consumption of the fuel version Camry is 5.7L； per 100 kilometers; The average fuel consumption of Camry twin engines is 4.1L per 100 kilometers.

• The dual-engine version saves 1.6L fuel consumption per 100 kilometers compared with the fuel version.
• No.95 gasoline is 7.51 yuan per liter.

Camry dual engine saves 12.016 yuan in fuel per 100 kilometers compared with the fuel version of Camry. Driving 100 kilometers can save fuel in 12 yuan. Is it worth buying a hybrid car?

If the extra 20,000 yuan for purchasing the dual-engine version is used as fuel money,

20 thousand yuan can buy 95 # gasoline 150200L L.

The dual-engine version saves 1.6L fuel consumption per 100 kilometers compared with the fuel version.

Then Camry twin engines need to travel 93,875 kilometers to save the extra 20,000 yuan.

However, more than 90,000 kilometers, in addition to operating vehicles, basically few car owners can save fuel and money.

If a private car travels 10,000 kilometers a year, it will take at least 9 years to save money on fuel return, so it is said that hybrid electric vehicles save fuel but not money.

Moreover, it is not the same as plug-in hybrid cars. Although plug-in hybrid cars are also fuel-efficient and do not save money, they can get a green card without purchase tax, which is suitable for car owners.

Therefore, the first unacceptable disadvantage of the hybrid electric vehicle is that it saves fuel and does not save money. With the working principle similar to that of the plug-in hybrid vehicle, it can’t be a green card!

The second disadvantage is that the engine is noisy.

The engine noise of hybrid electric vehicle is very loud, which I felt on Camry twin engines, but it is not disturbing all the time, mainly in two cases, the engine noise will be very obvious.

In the first case, the cold car starts.

When the battery is fed, the cold car starts again. At this time, the engine noise of Camry dual-engine will be very loud, and the engine noise can be felt in the whole underground garage. Sometimes it will be caused by traffic jams for a long time, which may be because the engine water temperature is low.

When the car is cold, the engine can’t reach the best state, but it needs to drive the motor to charge the battery, which leads to the noise of the engine increasing under the combination of these two States.

In the second case, when driving at high speed, the battery is strongly charged.

When the Camry twin engines are driving on the highway, the engine cannot directly drive the vehicle due to the hybrid characteristics of Toyota THS II, so the battery must be charged.

Because the vehicle runs at high speed, it requires high power. At this time, it is necessary to drive both the vehicle and the motor to charge the battery, which leads to insufficient engine power.

In order to complete these two working conditions at the same time, the engine can only increase the speed, because the self-priming engine can only obtain the best power output at high speed.

Therefore, when driving at high speed and the battery is strongly charged, the noise of the engine will become very large. If it is sensitive to noise, it will affect the driving experience.

The third disadvantage is that the battery capacity is too small, and the power connection will shake.

As mentioned earlier, the battery capacity of the Camry twin-engine is only 1.3kwh, so it can only travel at a low speed of about 2km, which means that the Camry twin-engine basically travels in hybrid mode.

However, when switching from pure electricity to hybrid mode, sometimes there will be jitter, sometimes very small, sometimes very large, and sometimes not at all.

This is related to the small battery capacity. When the battery feed is switched to the hybrid mode, the engine needs to drive the vehicle and the engine to generate electricity at the same time, so the engine power is insufficient, and the power connection jitter appears.

If the power is switched when the battery is fully charged, and the engine and the battery drive the vehicle at the same time, there will be no jitter.

Therefore, the jitter caused by too small a battery may be unavoidable. This shortcoming is actually good, but it is somewhat unacceptable for car owners who pursue perfection.

Replacing the battery is expensive, so drive carefully.

Toyota and Honda’s hybrid electric system can be said to be very mature, and they all adopt "shallow charging and shallow discharging" to extend the battery life.

As long as the battery capacity of Toyota THS system is lower than 60%, it will stop discharging directly, while that of Honda is 55%.

This has both advantages and disadvantages. The advantage is that the battery can always be kept at more than 50%, which can increase the number of battery cycles and prolong the battery life.

The disadvantage is that the battery capacity of the hybrid electric vehicle is very small, and it is lightly charged and discharged every time, which makes it impossible to switch the power output mode for a long distance, which may cause the body to shake.

Due to the protection methods adopted by Toyota and Honda for the power battery, under normal use, the battery will basically not decay to the point where it cannot be used normally or be damaged.

Moreover, Toyota guarantees the battery for 8 years or 200,000 kilometers, and Honda guarantees the battery for 10 years or 200,000 kilometers, so the owner does not have to worry about battery damage, and it is expensive to replace the battery.

However, if the battery is damaged by the owner, it is not cheap to replace a battery.

Theoretically, taking the Camry dual engine as an example, the battery capacity is only 1.3kwh. At present, the power battery is 1,300 yuan /kwh, and it is 1,300 yuan to change a battery, plus the working hours are up to 3,000 yuan.

In fact, according to the maintenance cost of replacing the power battery exposed by the owner, it is obvious that it cost 23,848 yuan to replace the battery.

Therefore, it is not cheap to replace the battery in a hybrid electric vehicle, but as long as you drive normally, you basically don’t have to worry about the cost of replacing the battery.

Advantages of hybrid gasoline-electric vehicle

Although I mentioned the disadvantages of hybrid electric vehicles, its advantages cannot be ignored.

1. Whether driving at high speed or in traffic jam, the fuel consumption is relatively stable, and the fuel consumption per 100 kilometers is basically about 5L, which is very suitable for car owners who often run long distances.

2. A tank of oil can run more than 1000 kilometers, so you don’t have to worry about mileage anxiety, and you don’t have to refuel frequently. In today’s fast pace of life, the time saved is money.

3. No matter under any working conditions, the power of the hybrid electric vehicle can come at any time, the power output is better than that of the fuel vehicle, and the power ride comfort and driving experience are incomparable to that of the fuel vehicle.

The extra cost of buying a hybrid electric car may not be able to save fuel and money, but the driving experience is great!

Write it at the end

Hybrid cars are worth buying, but not for everyone.

If you don’t use cars frequently, don’t run at high speed, and just commute to work, then a fuel car is enough.

If there are requirements for power, endurance and long-distance driving, then a hybrid electric vehicle is worth buying.

If you buy a hybrid electric car just to save money, then I advise you to think twice. Actually, it doesn’t save money. If you buy it rashly, it’s too late to regret it!

　　China Weather Network News "Others laugh at me for wearing thick clothes, and I laugh at others for being frozen." After a cold wave at the beginning of November, the cold air was uninterrupted, and many places in China experienced a night of winter. Today (November 10th), a new strong cold air has been delivered, with a sharp drop in temperature and a wide range of influence. It will go all the way south to northern South China, and 30 provincial-level cities will hit a new low in the second half of this year. Coincides with the "Double Eleven" period, it may not only be a shopping cart, but also a bone-chilling cold. China Weather Network launched a national early warning map of down jackets to see where it will experience bone-chilling cold, and it is necessary to wrap a long and thick down jacket.

　　National down jacket warning map released, two-thirds of the country needs down jacket protection.

　　At the beginning of November, affected by the cold wave, many places experienced a big reversal of cold and warm, taking off cool summer clothes and turning out warm equipment such as long pants and coats. However, the cooling is far from over, and a new cold air has been delivered. From now until the beginning of next week, a large-scale temperature bottoming contest will be held in the central and eastern regions of China, and 30 provincial-level cities will set a new low in the second half of this year.

　　According to Zhang Juan, a meteorologist of China Weather Network, this strong cold air process will boost the winter process in North China, Huanghuai and other places, and the impact will also go deep into the south, bringing about a big temperature dive, and two-thirds of the country needs down jackets to protect itself.

　　According to the national early warning map of down jackets launched by China Weather Network, three days from now, Northeast China, Inner Mongolia and other places will experience the freezing cold, and the areas that need to wear down jackets will go south with the main body of cold air and reach the northern part of South China.

　　On November 10th, the main body of cold air mainly affects friends in the north, Qinghai, most of Tibet, the northeast and the central and eastern Inner Mongolia. The lowest temperature can be reduced to -20℃ to -15℃, and it will be frozen in minutes when going out, and the temperature is below freezing point during the day. It is necessary to wrap a long thick down jacket in cold weather all day. Most of Xinjiang, North China, Huanghuai, Shaanxi-Gansu-Ningxia and other places will also experience the cold below freezing point in the morning and evening. For example, the lowest temperature in Beijing dropped to -3℃ on the morning of the 11th, which will set a new low in the second half of this year, and it is also necessary to keep warm and wind-resistant down jackets.

　　On November 11th, with the cold air heading south, the highest temperature in most parts of the south of the Yangtze River will drop to around 15℃. Although it is not as chilly as the north, the temperature will also hit a new low in the second half of this year. Coupled with the rain, the wet and cold feeling is obvious, and it is not enough to wear a coat. You can apply for a down vest.

　　On November 12, cold air continued to penetrate south, and the area where down jackets were needed was extended to the south of the Yangtze River. Like Changsha, the highest temperature on the 12th will drop to 9℃, so it’s time to put on a down vest. As the temperature drops in eastern Inner Mongolia, northwestern Shanxi, northwestern Shaanxi and some places in Xinjiang, it will be frozen all day, so it is necessary to wrap a long thick down jacket when going out.

　　After the cold wave crosses Nanling Mountain, its influence will be obviously weakened, and its influence on most parts of South China is a spent force. The cooling range is limited, and the maximum temperature will drop from 30℃ to about 20℃. The body feels slightly cool, long sleeves and coats are enough, and down jackets will continue to press the bottom of the box.

　　How to choose down jackets these three misunderstandings need to be avoided.

　　The footsteps of winter continue to press south, and the weather is getting colder and colder. Down jacket is essential as the ultimate warm artifact. China Weather Network has identified three misunderstandings in the selection of down jackets. Have you been recruited?

　　The quality of down jacket can be identified from the aspects of filler, bulkiness, softness and fabric, which can refer to the four-step method. At first glance, the filler can be identified. Check the label to find out the type and content of the filler. A down jacket with less than 50% cashmere can’t be called. Press twice to test the bulkiness. By pressing down the down jacket to test the bulkiness, the down jacket with high bulkiness has enough air layer to strengthen the warmth. Three touches, experience softness. Feel the softness of the down jacket by touching it. The down jacket with high softness has lower down stalk content and higher down feather content. Four beats, beat the down jacket to test whether the fabric is hairy.

　　The strong cold air process coincides with the "Double Eleven", and many small partners’ goods have already flown on the road, and the rain and snow weather brought by cold air may affect the progress of logistics and distribution. Snowfall will occur in Xinjiang, Qinghai and other places, and logistics may be blocked; There will also be a large-scale precipitation and logistics slowdown in the south. Vehicles are easy to slip in snowfall weather, which increases the hidden danger of traffic accidents and thus affects the timeliness of logistics distribution. Express logistics enterprises need to pay special attention to weather forecast and early warning and other relevant information, make emergency plans for sudden weather changes, strengthen after-sales service links such as logistics distribution and cargo transshipment, and minimize the impact of disastrous weather on logistics and transportation.

　　China Weather Network reminds us that this year’s "Double Eleven" express is under great pressure, and the delivery task of the courier brother is even more arduous due to the cold weather and inconvenient transportation caused by rainy and snowy days. If there is a short delay in delivery, everyone can give more tolerance and understanding. Finally, I wish everyone’s packages can arrive in time without being affected by the weather.

　　Pupils perform programming operations under the guidance of teachers. Photo by Zheng Jiawei

　　BEIJING, Beijing, December 22 (Zheng Jiawei) "Programming education is not to cultivate code farmers, but to cultivate students’ programming ability, and the most important thing is the process, which trains the way of thinking in the process of presenting logical thinking and finally solves practical problems in life." Dr. Yu Xiaoya, a professor at Beijing Institute of Education, said.

　　On the 21st, an observation activity and seminar on innovative classroom teaching of programming education in primary and secondary schools was held in Beijing. On the day of the meeting, teachers from all over the country gathered in the No.1 Primary School of Exhibition Road, Xicheng District, Beijing to observe the programming demonstration class provided by the No.1 Primary School of Exhibition Road, and discuss how to further cultivate students’ innovative thinking and practical ability after the course.

　　In the demonstration class, under the guidance of the teacher, the students in Grade 5 of the primary school used the programming cat tool to complete the animation production and the programming of the voice-activated lighting system, respectively. Many students said that they liked the hands-on operation in class very much and wanted to continue to play programming when they got home.

　　Guan Jiying, one of the two teachers who participated in the demonstration class, was responsible for teaching the programming of acoustic control lighting system. After the students finished the basic programming of acoustic control system, she further inspired the students to think about the practical application of acoustic control system, and finally guided the students to program the noise indicator system. When the surrounding voices were normal, the green light turned on, but when the voice was too loud, it turned red.

　　On July 8th, this year, the State Council issued the Development Plan of the New Generation of Artificial Intelligence, specifically proposing to implement the national intelligence education project, set artificial intelligence related courses in primary and secondary schools, gradually promote programming education, and encourage social forces to participate in the development and promotion of educational programming teaching software and games.

　　Zhu Hui, a researcher in Xicheng District, Beijing, said in an interview with Zhongxin.com that although the State Council issued a notice to add programming to the classrooms of primary and secondary schools, schools still need to choose appropriate programming tools in the actual operation process to make this requirement a reality.

　　According to Zhu Hui, programming education in Xicheng District has always been in the forefront of Beijing. From the first computer elective course in 1982 to the graphical programming language education with "programming cats", it has always focused on cultivating students’ procedural thinking and solving problems in real life.

On June 6th, the National Development and Reform Commission, the Ministry of Ecology and Environment, and the Ministry of Commerce once again pushed the development of new energy vehicles-"Implementation Plan for Promoting the Updating and Upgrading of Key Consumer Goods and Smooth Resource Recycling (2019-2020)" was released. The importance of this document can basically be understood as the main theme of the post-new energy vehicle era. That night, we took a look at the dynamics in the circle, which is roughly like this:

From a fundamental point of view, this is a promotion document for digesting production capacity nationwide, which is good for all companies in all industries, large and small. On the other hand, the switching of fuel vehicles in China is the icing on the cake. However, this Dragon Boat Festival, the vast majority of car companies and pile companies have spent a uneasy festival. To sum up, people who have no long-term worries will have near worries.

From the point of view of energy supplement, there are several points worthy of attention in this document: how to go in the future in the process of changing tracks from policy-driven to market-driven in China’s new energy automobile industry.

Judging from the logic of the new energy automobile industry in the full text of the policy, it mainly guides the industry from two aspects: encouraging the upstream and downstream of the new energy automobile industry to continue research and development, promoting cost reduction and efficiency improvement, perfecting the energy supplement system and improving the market application of new energy vehicles. The document specifically mentions that it is necessary to learn from the power exchange mode and application experience in the field of public services, and encourage enterprises to develop new energy vehicle products with the combination of charging and power exchange, flexible battery configuration and long driving range. Therefore, we feel it is necessary to show past lives, the power exchange mode, to everyone.

01 Sadness Xia Jiaxi and His Better Place

In 2007, Shay Xia Jiaxi put forward the power exchange technology, and then founded a power exchange company called Better Place in Israel. After the financing of $850 million was changed in 2013, Xia Jiaxi and his dream of Better Place collapsed. Even though the valuation reached an unprecedented $2.25 billion at that time, the hopeless power exchange model was ruthlessly abandoned by capital.

Xia Jiaxi’s Ambition and the Legacy of Better place

In the early days of its establishment, Xia Jiaxi foresaw that the power battery, a key component that directly affects consumers’ desire to buy, would not improve by leaps and bounds in the short term. The most direct way to solve the mileage anxiety is to form the same energy supply efficiency as fuel supply for fuel vehicles. The energy supplement market bred by the emerging industry of electric vehicles will directly subvert the existing energy structure and consumption mode. Under such a market positioning setting, Xia Jiaxi boldly left SAP.

One year after the establishment of Better place, Israel’s first "power exchange station" was established. First, it signed a cooperation agreement with Renault to provide 100,000 Fluence ZE electric vehicles (but the actual order was less than 1%). Better Place started with 750 drivers in Israel, and the charge for electricity exchange service includes battery rent and electricity exchange fee. Although the hardware cost, battery maintenance cost and education cost of consumers and enterprises were incomprehensible at that time, Xia Jiaxi did not hesitate to continue to burn money in Denmark and the United States, but at that time, car companies still had great doubts about the development of new energy vehicles, and the convenience and use cost of customer-side power exchange mode were not particularly different from those of traditional fuel vehicles. Better Place only launched thousands of vehicles around the world until it was closed.

The end of the road for Better Place seems to be ill-timed now. After all, the overall environment of the new energy automobile industry is far from the same. However, Better Place has left a complete chassis power exchange technology for future generations, and the value generated by the experience in the operation process is immeasurable.

02 Phased tasks of State Grid

863 Program-the Beginning of Power Exchange Technology

In 2006, the domestic electric vehicle industry was still in its infancy. The State Grid responded to the call of the country to start the electric vehicle project, and Zhejiang Power Grid is the top priority to implement the project. At that time, the first project leader of Zhejiang Power Grid participated in the project was Mr. Nie Liang (the first person in the domestic market application field of power exchange mode). In 2010, his team developed and completed the first licensed pure electric vehicle in China, and completed the reserve of basic power exchange technology. In the same year, Nie Liang was responsible for building the Zhejiang project of intelligent charging and replacing power service network. Different from Better Place, a pioneer in power exchange, State Grid developed a set of standard box power exchange technology after understanding the chassis power exchange technology. In Hangzhou, 500 power exchange taxis were piloted with Langyue and Prima models and high box standard boxes, and the business model of "separation of vehicles and electricity and mileage charging" was put forward and verified for the first time in this project.

Power exchange stations and standard boxes piloted by State Grid in Hangzhou

It can be said that the power exchange technology was basically a system at that time, and the pilot effect was quite satisfactory. Later, the Beijing-Shanghai trip organized by State Grid set a fire for the development of power exchange. What’s more interesting is that. In August 2010, State Grid joined the "China Enterprise Electric Vehicle Industry Alliance" and served as the chairman of the charging and service professional committee. At that time, State Grid determined the basic idea of its own intelligent charging and replacing operation mode, that is, mainly replacing electricity, supplemented by plug-in, centralized charging and unified distribution. In other words, the development direction of state grid is to change power stations, not. In line with the above development ideas, State Grid also reserves advanced technologies such as battery balancing, battery automatic replacement equipment and battery cascade utilization. These forward-looking explorations and pre-research have laid a solid theoretical foundation for the budding electric vehicle industry, pointed out the general direction of technical development, and established the development path and ideological system of the whole industry. Today, these technologies have been widely used, especially the chassis replacement mode and standard battery box technology, which have become the mainstream of domestic electric vehicles. However, during 2013 -2014, State Grid did suspend the project of replacing new energy vehicles with electricity due to the change of the main task direction of enterprises. We inquired about the relevant historical information and found that apart from the change of the main tasks of enterprises, the irreconcilable contradiction with car companies is also one of the development factors that hinder their power exchange mode. After all, no car company is willing to become a subsidiary of State Grid. At that time, a director of the National Development and Reform Commission once said: "State Grid should put its position right and cooperate with car companies to develop electric vehicles with a more open attitude."However, State Grid’s insistence on the power exchange mode is not only not conducive to its stable position in the electric vehicle infrastructure market, but also more likely to restrict the development of electric vehicles. In other words, the failure to get through the industrial chain has become the biggest factor for the grounding of the State Grid’s power exchange model. On the other hand, the national policies at that time, such as subsidies and the environment of new energy vehicles, were still relatively weak. Therefore, although the State Grid ran through the business model of power exchange, it was unable to open up the industrial chain to form a business ecology due to institutional factors, and it was inevitable to suspend the power exchange project.

03-The sharing mode has no future.

After the State Grid froze the power exchange mode, Tesla, an American star company, demonstrated its 90-second quick exchange technology in 2013, once again detonating the problem of changing the phone all over the world, but soon Tesla will develop specifically for supercharger 3. From a technical point of view, Tesla still follows the chassis power exchange idea of Better place, but it is further improved in speed. But when "Iron Man" saw the fatal defect of chassis-type power exchange-abnormal batteries can not be shared across car models, and the compatibility of power exchange stations is low, so low compatibility can not improve operational efficiency. It is even more unrealistic to integrate the resources of car companies and form a common standard. In such a complicated power changing environment, Tesla silently quit to change the power stage.

Schematic diagram of Tesla power exchange technology

The rise of 04 module box-splitting power exchange technology

In 2014, Nie Liang left the State Grid after seeing the possibility of opening up the industrial chain of the power exchange system and constructing the power exchange ecology. In the same year, Hangzhou Botan was established, and based on the power exchange of State Grid, the low-box standard box battery was further developed. Compared with the standard box of State Grid in 2010, the low-box standard box battery can be directly placed in the vehicle chassis (the original high-box standard box battery of State Grid needs to be placed under the back seat of the vehicle or in the trunk of the vehicle), and the stability and safety of the vehicle are greatly improved. On the other hand, at that time, the large-scale travel business began to exert its strength, and the market segment paid unprecedented attention to the operation economy of fuel and new energy vehicles. The split-box power exchange mode combined with the large-scale travel business perfectly solved the problems of operating costs and energy replenishment efficiency, and the module split-box power exchange ushered in its historical opportunity.

Standard charging cabinet and standard box batteries for module box-changing.

So, what is the principle of module splitting? First of all, the main dimensions of the TEU are completely the same, but according to the iteration of power battery technology, the energy density can be continuously improved. At present, the single TEU is mainly 15KWH (see the figure below). According to the requirements of vehicle models, different numbers of TEU power batteries are arranged on the vehicle chassis (2/4 for passenger cars and 6 or even 8 for logistics vehicles). Because the box size is the same at the initial stage of design, the power exchange station can exchange power for all vehicles using TEU, no matter which main engine factory they are made, thus completing the development of three limited power exchange modes: compatibility of power exchange equipment and vehicle models, compatibility of charging equipment with TEU, and recycling of circulating batteries.

05 Inventory of Power Exchange in China at the Present Stage

In 2016, the chassis replacement technology that sank for a period of time reappeared in the field of vision. This time, Cai Dongqing created Shanghai Aodong New Energy Automobile Technology Co., Ltd., and made continuous efforts in the power replacement business, and then quickly followed up. Sort out the development path of domestic power exchange technology, which is roughly as follows:

Mainstream power exchange technology: module splitting and chassis power exchange, as shown below:

It is worth noting that at present, the two modes of automatic route for power exchange are slightly different. Six-axis robots are mainly used for power exchange in modules, and RGV is mainly used for chassis change, which is roughly as follows.

Market application: Beiqi Weilai Xinchufeng is used for chassis power exchange, Dongfeng, Zotye, Universiade are used for module power exchange, and the number of vehicles put in and the actual mileage of operation are slightly superior.

How to compare the above two power exchange technologies?

We believe that it is not objective enough to compare the above two power exchange technologies only from the actual promotion layout level (such as infrastructure investment, power exchange capacity, site requirements and construction speed, etc.). The reason for this is the following：

Equipment level: manual, semi-automatic or full-automatic power exchange mode can also be selected for box-by-box power exchange, and the investment intensity can be selected according to the actual situation, while chassis power exchange can only be fully automatic, so it has higher capital requirements and limited investment flexibility in practical promotion. However, according to the fully automatic standard, the cost difference between RGV and six-axis robot equipment is not big.

Site expansion level: the chassis can be quickly laid out in containers for power exchange, and the landing speed is slightly faster, but some cities are not allowed to work in containers (such as Guangzhou). Therefore, in terms of policy compliance, the requirements for the construction of sub-box power exchange and chassis power exchange are basically the same.

On the aspect of power exchange capacity: in the fully automatic state, the average daily power exchange capacity can reach about 250 times with little difference. However, there is a point of concern in this respect. According to the public data, although there are more charging compartments in the power exchange stations with the same power exchange capacity, the number of vehicles that can be exchanged for electricity is only slightly more or equal to that of the chassis (we think that the future evaluation of power exchange capacity can not only rely on the single angle of power exchange speed, because the power exchange capacity depends on the number of charging compartments in the station energy supply, From this point of view, the general modular sub-box power station has 120 cells at the same level, while the chassis power station has 28 cells. However, one car in the modular sub-box power station consumes 4 cells on average, so the power exchange capacity of 120 cells, that is, 30 cars at a time, is not much different from that of the whole pad chassis power station with 28 cells. Therefore, there is little or no difference between the two modes from the above three aspects, so there is no way to compare them only from these three points.

With the issuance of the document "Implementation Plan for Promoting the Updating and Upgrading of Key Consumer Goods and Smooth Resource Recycling (2019-2020)", on the basis of encouraging the development of power exchange mode, requirements are put forward for battery modularization and step utilization of batteries. Therefore, which mode can be compatible with more types of vehicles, better connect the front and rear ends of battery step utilization and better adapt to the future modular development of automobile manufacturing is the more important focus.

From the perspective of vehicle compatibility, the power exchange mode should not be a limited energy supplement scene in the end, but an open source energy supplement mode, because the most basic and basic construction purpose of the power exchange station is to be used as a public infrastructure to facilitate public travel, otherwise why do you enjoy subsidies? At present, Beiqi, Weilai and other car companies are leading the chassis power exchange, because the batteries of their respective car companies are opposite-sex batteries compared with other OEMs, the power exchange sites or batteries cannot be universal. However, Dongfeng, Universiade, Zotye and other enterprises adopt the idea of modular box-splitting power exchange based on standard box batteries, which makes the power exchange station shared among different car models, and the battery can be shared, which greatly improves the utilization ratio of the site and the battery. Therefore, from this perspective, it is obvious that modular box-splitting power exchange is more suitable for the current concept of "sharing economy" and is also an intensive use of social resources.

From the point of view of power battery recycling, the mainstream design ideas in the industry at present are as follows

Direct view of step utilization of power battery

From the point of view of echelon utilization, we must first reduce the transformation cost in the process of each degradation, otherwise it will be difficult to land. From the top-level design point of view, the standard of battery should be unified first, and then the battery with smaller relative weight and volume (because it can’t be directly used in section B and section C if it still stays in the direction of the overall special-shaped battery of most models at this stage). Only under these two preconditions can the whole life cycle development of battery be maximized, and the average use cost of power battery at the user’s end will be lower.

Therefore, from the perspective of battery recycling, it is obvious that the case-by-case power exchange built by the standard box system is more in line with the policy and national conditions. However, from the perspective of automobile enterprises, the whole chassis-type power exchange has less changes to the chassis of the whole vehicle body, and the technical level is relatively easier to realize; However, the modular box-changing technology requires higher requirements for body chassis modification and design cycle. However, it is very interesting that the number of car companies that accept the standard box-splitting power exchange system is far more than that of the chassis-type power exchange model (the total number of cars that are actually put in the box-splitting power exchange system is also more than that of the chassis-type power exchange system). It can be said that many car manufacturers are doing power exchange, and obviously many car companies do not want to play with tickets at this level, but stand higher and look farther.

07 written at the end

On June 5, 2016, China Tower established an energy company with a capital of 5 billion yuan to take the lead in entering the terminal market of power battery ladder utilization, which made it possible for standard box batteries used by modular box-changing electric vehicles and power-changing technology companies to be used in large-scale terminals (compared with special-shaped batteries). The integrity of power battery ladder utilization has been further improved, while the extension of battery ladder utilization industrial chain has further reduced the average use cost of power batteries, which will indirectly reduce the consumption cost of new energy vehicles. From the perspective of industrial chain, does it mean modularity?

We gave time to this problem, but for enterprises that insisted on changing electricity in the early stage, in June 2019, the wind started.

Cctv newsOn April 19th, "News Network" reported that the agricultural and rural economy made a steady start in the first quarter, the foreign trade made a steady start in the first quarter, and emerging markets remained dynamic … … With the intensive release of positive signals, China’s high-quality economic development has a long way to go.

　　The agriculture and rural economy started steadily in the first quarter.

　　The State Council Press Office held a press conference on April 19th. The relevant person in charge of the Ministry of Agriculture and Rural Affairs said that since the beginning of this year, China’s agricultural and rural economy has maintained a good momentum of development.

　　This year, the intended planting area of grain reached more than 1.78 billion mu, an increase over the previous year. Effectively deal with the freezing rain and snow and cold wave weather last winter and this spring, and strengthen technical guidance services. Winter wheat grows better than last year and all the year round, and the foundation for a bumper harvest of grain and oil production in summer is gradually laid down, and spring ploughing production is vigorously and orderly promoted. The supply of "vegetable basket" products is abundant, the production capacity of pigs is adjusted and optimized, the production of meat, eggs and milk is increased in an all-round way, and the supply of vegetables and fruits is stable.

　　Rural industries have a good momentum of development. In the first quarter, the added value of agricultural and sideline food processing industries above designated size increased by 3.3% year-on-year. Rural leisure tourism continues to heat up, and e-commerce of agricultural products grows rapidly. The per capita disposable income of rural residents reached 6,596 yuan, 2.4 percentage points higher than that of urban residents.

　　Rural construction and governance have been solidly promoted. By the end of March, the county-level rural construction project library had accumulated 614,000 projects and implemented project funds of 250.74 billion yuan.

　　Multi-measures to promote sustained recovery of consumption and promote high-level opening up.

　　At the press conference held by the State Council Information Office on April 19th, the relevant person in charge of the Ministry of Commerce said that in the first quarter, foreign trade made a steady start, emerging markets maintained vitality, and developed markets recovered. A survey of key foreign trade enterprises by the Ministry of Commerce shows that enterprises reflecting employment growth accounted for 1-mdash in March; In February, it rose by 1.7 percentage points to 88.8%, and the confidence expectation of enterprises was further enhanced.

　　Foreign investment maintained steady development. In the first quarter, non-financial foreign direct investment was 242.92 billion yuan, up by 12.5%, among which investment in ASEAN and EU grew rapidly, with growth rates of 36.7% and 34.5% respectively.

　　In the next step, the Ministry of Commerce will focus on promoting the continuous expansion of consumption, launch a series of activities around the theme of "Enjoy the benefits of the whole people throughout the year", focus on the cultivation and construction of international consumption center cities and the construction of modern business circulation system, and continue to introduce relevant policies and measures to continuously release consumption potential.

　　Link the world! The cumulative number of overseas buyers attending the Canton Fair has exceeded 120,000.

　　April 19th is the last day of the first phase of the 135th Canton Fair. During the five-day exhibition period, we felt the "attraction" of the Canton Fair, as well as the "centripetal force" of linking the world with new products and technologies.

　　As of April 18, the cumulative number of overseas buyers attending the meeting offline has exceeded 120,000, an increase of 22.7% over the same period of last year. They come from 212 countries and regions around the world. Not only the number of people has increased, but also the sources are all over the world. The top countries include India, the United States, Nigeria, Indonesia and Malaysia.

The quantity of spring ploughing agricultural materials is generally sufficient and the quality is guaranteed.

On April 19, the relevant person in charge of the Ministry of Agriculture and Rural Affairs said that the consumption of spring ploughing fertilizers, pesticides and seeds accounted for about half of the annual consumption. Judging from the current situation, the number of seeds, pesticides and fertilizers ploughed in spring this year is generally sufficient.

At present, the rate of fertilizer in place at the provincial and county levels has reached 95% and 90% respectively. The quality of agricultural materials is guaranteed and the prices are relatively stable. The prices of most varieties have declined, but they are still at a historical high level. Generally speaking, the supply of agricultural materials is timely, which can meet the needs of spring ploughing production.

　　Water supply will be completed in 2026! The progress of this major water conservancy project benefiting 14 million people is updated.

　　On April 19th, the largest single project of the second phase of the project of diverting water from Han to Wei — — The pylon of Weihe River Pipe Bridge is about to be completely capped, laying a foundation for ensuring that the second phase of the project of diverting water from Han to Wei River will be completed in 2026.

　　The project of diverting water from Han River to Wei River connects the two major water systems of Han River and Wei River, which is one of the 172 major water conservancy projects planned by the country in the 13th Five-Year Plan.

　　The second phase water transmission and distribution project of diverting water from Han to Wei is an important part of the project, which consists of Huangchigou water distribution hub, south trunk line project and north trunk line project, with a total length of 190 kilometers. It undertakes the key task of transporting Hanjiang River water to 21 targets in four key cities, including Xi ‘an, Xianyang, Weinan and Yangling, 11 county-level cities, 1 industrial park and 5 new cities in Xixian New Area on both sides of Weihe River, which is very important for bringing into play the overall benefits of the project.

　　After the completion of the second phase of the project, 1.5 billion cubic meters of water can be transferred from the Han River every year, and a "north-south allocation" water channel has been added to the main skeleton center of the national water network, which plays an important role in realizing the spatial balance of water resources allocation in China and ensuring the high-quality development of economy and society.

In addition, the second phase of the project of diverting water from Han to Wei covers more than 14 million people, which ensures the water supply safety in Xi ‘an, Xianyang, Yangling and Weinan in Guanzhong Plain of Shaanxi Province, and will also greatly solve the contradiction of more water resources in the south and less water resources in the north and provide support for high-quality economic and social development.
