Jing Zheng Ban Fa [2009] No.105

The people’s governments of the districts and counties, the commissions, offices and bureaus of the municipal government, and the municipal institutions:

　　Since October, the number of reported cases of influenza A (H1N1) and the number of clustered epidemics in this city have risen sharply, showing a sustained and high incidence trend, and severe cases and deaths have appeared one after another. The State Council and the municipal government attached great importance to it and held a series of meetings to study and deploy the prevention and control of influenza A (H1N1) in autumn and winter. On October 31st, Premier Wen Jiabao went to Beijing Children’s Hospital to learn about the prevention and control work and made important instructions. On November 2nd, Comrade Liu Qi and Comrade Guo Jinlong went to the Municipal Health Bureau to inspect and guide the prevention and control of influenza A (H1N1). On the basis of fully affirming that the prevention and control work in this city has achieved a major victory in stages, the prevention and control work of influenza A (H1N1) in autumn and winter was redeployed in view of the grim situation facing the current epidemic situation. In order to conscientiously implement the spirit of the relevant meeting of the State Council and the municipal government, further improve the prevention and control of influenza A (H1N1) in the city, and effectively cope with the larger epidemic peak, with the consent of the municipal government, the relevant matters are hereby notified as follows:

　　First, strengthen organizational leadership and strengthen the implementation of various measures.

　　All regions, departments and units should continue to strengthen leadership, adhere to the working principle of "according to law, scientific, standardized and orderly", adhere to and improve the effective prevention and control measures in the previous stage, adhere to territorial management, strengthen the "four-party responsibility", strengthen supervision and inspection, implement accountability, make good preparations for emergency plans under the most difficult conditions, carefully organize and take effective measures to strictly prevent and control large-scale spread and cluster outbreaks of the epidemic, and reduce

　　Two, highlight the school prevention and control, timely adjustment of prevention and control measures.

　　(a) continue to adhere to the school as the focus of prevention and control work. Education, health departments and schools at all levels should work together and fulfill their duties, strictly implement the provisions and requirements of school prevention and control work, effectively monitor and report the epidemic situation, further strengthen health education and health management for students and faculty, and minimize large-scale gathering activities. Education, disease prevention and control and health supervision departments at all levels should strengthen inspection and supervision, and schools that violate the relevant provisions of the Ministry of Health and the Ministry of Education and whose prevention and control measures are not in place should be seriously investigated for responsibility.

　　(2) Appropriate adjustment and improvement of school prevention and control measures. With the coming of winter, the school no longer carries out outdoor body temperature monitoring at the school gate, but instead measures the body temperature at home for primary school students, and at the same time strengthens the afternoon examination for middle school students. Appropriately adjust the school suspension standard, and change it to take suspension measures when the number of concentrated fever in the same class exceeds 20%; The Municipal Education Commission should be responsible for checking and registering social remedial classes, stop unnecessary weekend cram schools and remedial classes in accordance with the principle of "no need to hold them", further reduce the risk of infection among students, and take the lead in formulating the adjustment standards for school temperature monitoring, suspension of classes and resumption of classes for students in conjunction with the Municipal Health Bureau.

　　(three) timely diagnosis and investigation of school cases. Students who have flu-like symptoms at school or at home should go to the hospital at the first time, or the district and county disease control departments should go to the door for investigation. After being identified as influenza A (H1N1) or seasonal influenza, measures such as hospital treatment or home isolation should be implemented according to the condition. Health supervision departments should closely supervise and inspect the implementation of school prevention and control work.

　　Third, do a good job in medical treatment to reduce serious deaths.

　　(a) to do a good job in early diagnosis and medical treatment of critically ill patients. Adhere to the principle of concentrating patients, experts, resources and treatment, and integrate superior resources to minimize severe cases and deaths. It is necessary to give full play to the role of traditional Chinese medicine in the prevention and treatment of influenza A (H1N1), accelerate the transformation of research results of traditional Chinese medicine in this city, and do a good job in scientific research and countermeasures for severe cases. The medical treatment of patients with influenza A (H1N1) shall be charged in accordance with the relevant provisions of the Notice of the General Office of the Ministry of Health and other four departments on the medical treatment expenses of influenza A (No.137 [2009] of the Health Office).

　　(two) to further strengthen the epidemic monitoring work. All relevant medical and health institutions should closely follow the changes of the epidemic situation, scientifically judge the development trend of the epidemic situation, and constantly improve the response plan and work plan. The Municipal Health Bureau shall organize and formulate relevant measures for key monitoring of influenza A (H1N1) virus, and strengthen the ability of disease surveillance.

　　(3) Strengthen hospital management and guide reasonable and orderly medical treatment. Medical institutions should strengthen the investigation and treatment of fever and flu-like symptoms in outpatient and emergency departments, and guide patients to seek medical treatment in a reasonable and orderly manner. All districts and counties should take corresponding measures to encourage citizens to go to community health service institutions and secondary hospitals to reduce the pressure of treatment in tertiary hospitals. Patients and medical staff must wear masks, and mask distribution points should be set at the entrance of the hospital to prevent cross-infection in the hospital.

　　(four) to strengthen the reserve and market security capabilities of relevant emergency materials and rescue drugs. It is necessary to focus on the mask reserve and the distribution and replacement of municipal reserve Chinese medicine to various medical institutions at all levels to ensure the orderly development of medical treatment.

　　Fourth, accelerate vaccination and establish an immune barrier for the whole society.

　　We should conscientiously implement the spirit of Comrade Liu Qi’s instruction that prevention and control of influenza A (H1N1) should be based on "playing the first move and fighting the initiative", adhere to the combination of social mobilization and citizens’ voluntary participation, and actively and orderly speed up the second phase of influenza A (H1N1) vaccination. In accordance with the principle of "informed consent, voluntariness and free of charge", priority should be given to ensuring the vaccination of key populations and opening up the vaccination of citizens. Adhere to territorial management, and all regions should do a good job in organizing and managing vaccination; Health departments at all levels should strengthen supervision and management and implement the daily reporting system.

　　It is necessary to carefully organize and scientifically arrange, speed up the progress of influenza A (H1N1) vaccination for key groups such as students, the elderly and social public service personnel, coordinate the central units and military hospitals to assist in vaccination, complete vaccination for primary and secondary school students in mid-November, and complete vaccination for other members of society in mid-December, and accelerate the establishment of the whole society’s immune barrier. At the same time, we should pay close attention to, closely monitor, report in time and effectively deal with all kinds of adverse reactions and coupling events during vaccination.　

　 　 　 　Five, strengthen publicity and education, and correctly guide public opinion.

　　Led by the Propaganda Department of the Municipal Party Committee and coordinated by relevant departments, a publicity column on the prevention and control of influenza A (H1N1) was opened in major municipal media and websites to further popularize the knowledge of influenza prevention and control to the public, publicize the effectiveness and safety of the vaccine, and enhance the conscious awareness and ability of the whole society. Experts in the field of public health should be invited to publicize and cultivate good personal hygiene habits, such as wearing masks for medical treatment and washing hands frequently, emphasizing that it is not only an effective means of protection, but also a manifestation of personal responsibility and civilized quality. It is necessary to publish epidemic information in a timely, open and transparent manner, clarify false reports, guide the public to respond to the epidemic scientifically and rationally, maintain the normal production and living order of society, and ensure social stability. It is necessary to timely convey the prevention and control work of the municipal party Committee and the municipal government, the measures to facilitate the people and the information on work adjustment to the general public.

　　Six, encourage citizens to do personal prevention, reduce the risk of infection.

　　Adhere to prevention first, actively encourage citizens to do personal prevention, develop good personal hygiene habits, and promote the improvement of the health quality of the whole people. In order to reduce the risk of infection and transmission, the public is encouraged to take the following personal protective measures:　

　　(1) Wash your hands frequently. Wash your hands frequently according to the correct hand washing method. When coughing and sneezing, use paper towels to protect and cover your nose and mouth. Keep the air fresh and ventilated indoors, and develop good hygiene habits.

　　(2) Wear a mask. When citizens feel unwell or go to the hospital, I and the accompanying staff should wear masks. All hospitals should have enough masks at the entrance of the hospital to meet the needs of the doctors.

　　(3) Scientific home observation. When influenza-like cases occur in the family, indoor ventilation should be strengthened. Patients should live in single rooms and try to avoid contact with other family members.

　　(4) Improve your own immunity. Individuals should keep enough sleep, strengthen exercise, pay attention to increasing or decreasing clothes and pay attention to reasonable diet.

　　On May 5, 2017, people with big plane dreams came to a small slope outside the fourth runway of Shanghai Pudong International Airport early, waiting for the exciting moment. On this day, it was the first flight day of C919, a large jet passenger plane independently developed by China, and the small earth slope outside the runway was affectionately called "Wangjiupo".

　　With the roar of the engine, the first C919 large passenger plane, piloted by captain Cai Jun and co-pilot Wu Xin, took off from the fourth runway of Pudong International Airport at 14: 00, rushed into the sky, and landed successfully 79 minutes later. After nine years of scientific research, numerous tests and technical debugging, there is once again the shadow of domestic large aircraft in the blue sky, which indicates that China has entered the ranks of a few countries with the ability to develop large passenger aircraft.

　　Now, more than two years have passed. What’s the progress of airworthiness certification of C919 passenger plane? When can Chinese get on a large domestic plane? Recently, the reporter came to China Commercial Aircraft Co., Ltd. for a field visit.

　　Yun -10: Leaving an innovative gene is an attempt to commercialize domestic aircraft.

　　Arriving at the Pudong base of China Comac Shanghai Aircraft Manufacturing Co., Ltd., I saw a large plane with a white fuselage and several blue and white stripes sleeping peacefully on the lawn of the industrial park, with a bright red flag on its tail. This unique large passenger plane in the world soared in the blue sky of China more than 30 years ago, and its name was Yun -10.

　　Boarding the Yun -10 plane, the reporter was shocked by the industrial level at that time. The throttle lever, pedals, various instrument panels and indicator lights in the cockpit are reasonably arranged and fully functional. In addition to the seats for the main driver, the co-pilot and the pilot, there is also a seat for the mechanic. When the aircraft breaks down in flight, the mechanic can go down to the inside of the aircraft from the passage next to the seat for maintenance. When you come to the cockpit, the passenger seat is no different from the common big plane now, except that the distance between the front and back of the seat is larger, the ride experience is more comfortable, and there is an ashtray on the armrest.

　　In August 1970, with the approval of Comrade Zhou Enlai, the state agreed that the report on trial production of transport aircraft in Shanghai should be centralized by the Ministry of Aviation Industry. The mission name is "Project 708" and the aircraft code is "Yun -10". According to statistics, at that time, more than 300 factories, research institutes and universities in 21 provinces, autonomous regions and municipalities participated in the development of Yun -10 aircraft.

　　On September 26th, 1980, Yun -10 successfully made its first flight in Shanghai. Subsequently, Yun 10 flew all over the country, reaching 10 cities, including Beijing, Harbin, Urumqi, Guangzhou, Kunming, Chengdu, Hefei and Zhengzhou. The longest time for a single flight was 4 hours and 39 minutes, and it completed a scientific test flight that flew over 3,600 kilometers in 3 hours and 42 minutes. Its performance and use characteristics fully met the design requirements. Yun -10 also flew over the Himalayas to Tibet seven times, transporting more than 40 tons of urgently needed materials for Xizang Autonomous Region.

　　Although the Yun -10 aircraft project was not officially put into commercial use for various reasons, the Yun-10 spirit of "independence, strong cooperation, selfless dedication and continuous innovation" has been passed down from generation to generation by large aircraft people.

　　Next to the lawn where Yun -10 plane docked, there stands a sculpture engraved with the four characters "Never give up", which is a solemn promise from the heart of the big plane people and the earnest expectation of hundreds of millions of people for the early commercialization of domestic big planes.

　　Time has entered the new century. In February 2000, the state decided to support the production of domestic civil aircraft and accelerate the development of regional air transport. In June, 2002, the State Development Planning Commission issued a document officially approving the establishment of the new regional aircraft project. The result is a new turbofan regional plane that has soared in the blue sky of China today — — Arj21 (advanced regional jet for 21st century) means advanced jet regional aircraft in the 21st century. ARJ21-700 is its basic model, and it is the first time that China has developed and produced regional aircraft in strict accordance with the internationally accepted regulations on aviation airworthiness management.

　　ARJ21: Delivered the 21st aircraft, accumulating valuable experience for the civil aircraft industry.

　　Not long ago, on November 29th, Comac China delivered the 21st ARJ21-700 aircraft to its customers. Talking about the differences between civil airliners and other aircraft, Ye Chao, deputy director of ARJ21 Division of China Comac Shanghai Aircraft Manufacturing Co., Ltd., has a lot to say: "The independent development of a jet regional aircraft needs to go through the processes of design, trial production, test flight, evidence collection, production, etc. This is not all. To make the aircraft truly commercialized, it must be tested by the market. If the requirements of airlines cannot be met, the cost performance ratio is low, and the experience of drivers, flight attendants and passengers is poor, the mission of the aircraft will not be truly completed. "

　　In the process of design and development, the ARJ21-700 aircraft has fully considered the number of seats, comfort and the needs of the aviation market in western China. Compared with similar aircraft, the cabin of ARJ21-700 aircraft has a higher and wider cabin, the cabin height is more than 2 meters, reaching the same cabin comfort as that of narrow-body aircraft, and the cabin height is close to 1 meter, which can provide more luggage space for passengers. The economy of the aircraft is also more prominent, and the engine fuel consumption is low. In order to adapt to the complex geographical environment in the west of China, the ARJ21-700 aircraft pays attention to take-off and climb performance in design, and can take off and land in a short distance, which has a strong advantage in the adaptability of western routes and western airports.

　　Although customers’ needs were fully considered in the design and manufacture, when facing the customer representatives seriously, Comac found that there were many details to be perfected. Because, from "product" to "commodity", the difference is not just one word, but also thousands of times of self-improvement and continuous collision with customers.

　　In Ye Chao’s view, there were three "self-revolutions" on the sales road of ARJ21-700. "When we sold the plane to Chengdu Airlines for the first time, it was the first time that we delivered the plane to our customers. During the continuous running-in, we found that some problems that we had never thought of were exactly the concerns of our customers. The second time ‘ Self-revolution ’ When the plane was delivered to Tianjiao Airlines. We have changed from serving one customer to serving two customers, which requires us to be more refined in technology and operation specifications. Now we are facing the third time ‘ Self-revolution ’ New customers such as Air China, China Eastern Airlines and China Southern Airlines will put forward more new requirements for our products. In the future, we should look at production from the perspective of creating handicrafts. "

　　Since the commercial operation of the ARJ21-700 in June 2016, the optimization and improvement of the aircraft production process has been carried out almost every day. "For example, the pilot’s operation has been greatly modified to reduce the pilot’s workload; In order to reduce the noise in the engine room, the conventional sound insulation cotton material is replaced by metal damping layer and rubber sound insulation material; In order to reduce the airflow noise at the air outlet of the air conditioner, silencers are installed, and there are various optimizations for flight attendants and aircraft maintenance personnel. " Ye Chao said.

　　With more and more orders, the mass production capacity of ARJ21 has gradually improved. In 2017, it will produce 4 aircraft, in 2018, 11 aircraft, and strive to produce more than 20 aircraft in 2019. Behind the digital beat is the continuous improvement of the overall efficiency of the workstation and the efficiency of skilled workers. Comac China has continuously promoted the innovation of production management in terms of process technology, on-site management, production operation control and so on. From January to September this year, the batch production rate of ARJ21 aircraft increased by 76.9% compared with the same period in 2018.

　　The development of ARJ21 regional jet has accumulated valuable experience for the development of China civil aircraft industry. After the whole process of jet regional aircraft design, trial production, test flight, evidence collection, production, delivery and operation, China has the development capability and airworthiness certification capability of jet regional aircraft, and people have more confidence in the future of large passenger aircraft projects.

　　C919: All tests are carried out in parallel, and the test will be prepared for "evidence collection".

　　In the avionics system comprehensive laboratory of Comac Shanghai Aircraft Design and Research Institute, researchers are busy, and the indicator lights are flashing on the rows of computers. On the monitors one by one, the program codes pass by in turn, and the C919 aircraft is being tested and verified here.

　　Walking into the iron bird test-bed of C919 aircraft, the test-bed in front of us looks like an "iron bird", except that it can’t fly, and its shape and internal structure are basically the same as the real C919 aircraft, so it can be called a simulation aircraft. The integration tests of flight control, landing gear, hydraulic system, etc. are all completed here. After the command is issued from the console, Iron Bird completes the relevant specified actions, confirms and verifies that the system design meets the requirements of product development, and ensures flight safety. The international mainstream aircraft manufacturers have completed the technical verification and technical improvement of related models through the Iron Bird test bed. "In addition, it has another function: when the flight test of the C919 aircraft fails, we can simulate it through the iron bird test bed and find a solution to the failure." Li Tao, director of the construction of the State Key Laboratory of Civil Aircraft Simulation Flight of Shanghai Aircraft Design and Research Institute, said, "At present, we are intensively carrying out the airworthiness verification test of the laboratory."

　　Isn’t the C919 plane already empty? What are the researchers still busy with?

　　"We are working on the airworthiness certification of the C919 passenger plane, that is, ‘ Textual research ’ . At present, laboratory tests are being carried out here, in addition to on-board ground tests, flight tests, simulator tests and supplier product identification tests. After the success of the R&D test flight of the C919 passenger plane in 2017, it still needs several stages of test flight and airworthiness evidence collection before it can be delivered to the airlines. " Li Tao said.

　　In order to ensure the efficient ground test and flight test on board, "in October this year, 105 aircraft completed the first test flight, and the number of aircraft used for flight test will reach 6 in the future, and related flight test work is being carried out in parallel." Nan Guopeng, captain of 105 aircraft of C919, introduced.

　　Simulator tests are also being carried out in an orderly manner in Shanghai Aircraft Design and Research Institute. Boarding the C919 passenger aircraft engineering simulator, this equipment looks like a big ball, and its interior is almost the same as the real aircraft cab. Li Tao introduced: "The simulator can undertake the test tasks such as aircraft control law evaluation, cockpit evaluation and safety evaluation. At the same time, it can also undertake the training and training of test flight crews to help pilots understand aircraft performance as soon as possible. "

　　It is understood that before the C919 large aircraft is delivered for use, it is necessary to obtain three certificates, namely: type certificate (TC), indicating that the aircraft design is safe and seaworthy; Production license (PC), which indicates that the aircraft manufacturing system meets the requirements and can be produced on a large scale; Single Airworthiness Certificate (AC) proves that a single aircraft is in a safe and available state, which is equivalent to the "driving license" of a car. These work plans will take two to three years to complete. If they go well, Chinese will be able to take a large domestic plane designed and manufactured by himself in the near future.

　　In addition to the joy and pride of flying in a large domestic plane, the development of C919 has a long-term strategic significance. It is not a simple product, nor is it an ordinary commodity. The manufacture of large passenger aircraft is known as the "crown of modern industry", which plays a very significant role in driving the civil aviation industry and modern industry.

　　From the perspective of aviation industry, with Shanghai as the leader, more than 200 enterprises and nearly 200,000 people from 22 provinces and cities including Shaanxi, Sichuan, Jiangxi, Liaoning and Jiangsu participated in the development and production of large passenger aircraft projects. The China civil aviation industrial chain, value chain and innovation chain driven by the C919 large passenger aircraft have great energy, and at the same time, it has promoted the establishment of 16 joint ventures in airborne systems such as avionics, flight control, power supply, fuel and landing gear, which has promoted the civil aircraft industry in China.

　　From the perspective of upgrading the modern industrial level, a commercial aircraft consists of 3 million to 5 million parts. These parts need to be produced by thousands of suppliers, which can promote the group breakthrough of key technologies in the fields of new materials, modern manufacturing, advanced power, electronic information, automatic control, computer and many other basic disciplines. "There are many domestic suppliers involved in the parts of the C919 passenger plane, and the fuel tanks, valves and landing gear equipment of the hydraulic system are all produced in China. Through the C919 project, we have grown together with our suppliers. " Li Tao said.

　　At dusk, when leaving Shanghai Aircraft Design and Research Institute, the research building was still brightly lit. In order for the C919 to be delivered as soon as possible and soar in the sky, another night for technicians began … …

　　Interview notes

　　It takes only 4 hours and 18 minutes to get from Beijing to Shanghai by high-speed train, but it is not necessarily faster than the high-speed train, not counting the waiting time for the flight to take off and queue up. However, this reporter still chose to fly because he had a question in his heart — — When can we get on the big plane made by Chinese himself?

　　Not long ago, I was chatting with a friend. When he heard that all the large passenger planes we are taking now are foreign products, his face showed a very surprised look: "What? However, our fighter plane, the National Day military parade is so beautiful, and manned space flight has already sent astronauts out of the earth. How can we buy a foreign plane? " The reporter told him: "It won’t take long. I will definitely bring you back the latest progress when I go to Comac for an interview this time. "

　　The plane rushed into the sky and entered the stratosphere. The reporter took out the "Safety Tips" from the front seat pocket and saw that the plane on flight CA1855 was Boeing 787. Thinking of a news I just saw recently, the order for C919 large aircraft has exceeded 1,000. Maybe a few years later, the reporter will watch Safety Tips again, and the models on it will be different.

　　With countless questions, I came to Pudong base of Shanghai Aircraft Manufacturing Co., Ltd. and Shanghai Aircraft Design and Research Institute. The reporter finally knew why civil aircraft manufacturing was so difficult. What is carried on it is not goods, nor one or two people, but dozens and hundreds of lives, and there is no room for any safety problems. In addition, the performance requirements of civil aviation aircraft are also very high. During the service period, an aircraft generally has to go through 60,000 flight cycles (take-off and landing) and 90,000 flight hours, with a service life of 30 years or more. Even some seemingly unremarkable parts on the plane must be used stably and safely for decades. In order to compete with the world aviation market, the large aircraft we build must be safer, more comfortable, more environmentally friendly and more economical than others, so as to have a broad market.

　　The big plane people are working hard for all this.

　　In an interview, the reporter really felt their busyness and dedication. The interview was interrupted several times by phone calls, and the interviewee repeatedly pressed the phone for fear of influencing reporters to ask questions. When a reporter asked a researcher at Shanghai Academy of Aeronautics and Astronautics, "Are there any touching stories in your work?" He smiled and said, "It’s nothing. Everyone usually completes the test task seriously." The colleague sitting on the side couldn’t help it. She grabbed the conversation and said to the reporter, "Our researchers are really selfless. Many technical backbones are in their thirties and forties, old and young. In order to complete the airworthiness forensics work as soon as possible, they basically work overtime every day. You will know when it gets dark." Hearing this, the former researcher who said there was no story was somewhat silent. He said, "Last Friday, I got home after 10 o’clock in the evening and found that my wife didn’t let the children sleep. When I thought about it, I went out early and returned late. The child has not talked to me for a week. " These little details permeate all aspects of the interview, which is moving.

　　When leaving the interview, the reporter remembered the 16 Chinese characters hanging on the wall of the C919 assembly workshop — — Long-term struggle, long-term research, long-term hardship and long-term dedication, after the delivery of more than 20 ARJ21, the C919 will also be delivered in the next two or three years, and the CR929 wide-body passenger aircraft jointly operated by China and Russia will also start construction in the next few years.

　　Let’s look forward to it. In the blue sky, there are more and more domestic passenger planes.

The evaluation criteria for technology are actually the most basic, and higher-level brand, culture, and cognitive construction are the high-level operating ideas.

Therefore, when we look at a car, we cannot simply analyze it from a technical perspective. Technology is just the fundamentals of building a product, but in this passenger car market, what people pursue when buying a car is not simply the product itself, but also the subsidiary value brought by the brand and design.

Looking back at what I’ve said, many companies have stumbled on these things.

The Volkswagen Phaeton produced by the same factory as Bentley is no less expensive, luxurious, and prestigious than the A8L, an executive-level sedan, but it has been beaten up in the market.

The fundamental reason is that brands are out of touch with market awareness, positioning, and pricing.

For example, the Lexus ES and Camry have similar platforms and power structures. The opinion of the Lexus ES "shell replacement" Camry has always been there, but it does not affect the sales of the Lexus ES at all.

On the basis of product technology, analyzing and considering the acceptance of user groups, brand culture construction, and product pricing differentiation, a car can be reasonably and rationally evaluated.

Using technology to market upwards is actually the most entry-level and lowest-level marketing strategy.

For example, Lynk & Co 09 is a very typical, primary, and entry-level "technical marketing" product. It is deeply similar to the Volvo XC90 in terms of marketing, and the two cars of the same platform and size are hard to move.

Indeed, from a platform perspective, Lynk & Co 09 is a platform subsidiary of the Volvo XC90, but it is not very closely related to the Volvo XC90.

On the one hand, the commonality of products can not be interpreted by pure technology, especially more than 200,000 high-end models, product support is no longer in cost, technology, but in the brand, product premium ability, design ability to pay.

On the other hand, there are not many technical similarities between the products themselves, and the modular vehicle manufacturing platform is very complete. It is impossible for enterprises to create an independent platform for each size of vehicle. The cost is too high and the cycle is too long. It is very necessary for the existing platform to produce models such as 369.

For example, Volkswagen’s MLB platform can produce both A4L and Urus. The platform is just one of the technologies that determine the product’s capabilities, but it is not the only one.

Basic materials: boron steel strength and ratio of body-in-white, sound insulation cotton materials, material selection, procurement cost of detailed configuration, excellent grade, core debugging aspects: data support for autonomous driving, debugging of power system, injection of control genes, control of quality control system, pros and cons of production line, and supplier requirements.

These are all invisible gaps.

Indeed, 300,000 Lynk & Co 09 has become the king in this level, but the results of the dead Volvo XC90 are not outstanding, the main reason is that users do not pay, 300,000 and 600,000 models have a huge sense of tearing.

On the one hand, the client base is completely different, on the other hand, Volvo’s competitiveness in the brand safety, brand culture construction direction, Lynk and Volvo have different directions, Lynk 09 client base and Volvo XC90 users also have a certain deviation.

Taking a step back, if the Lynk & Co 09 and Volvo XC90 that 300,000 can buy are products of the same level, then it means that 600,000 Volvo XC90 is not necessary for mass production.

So did Lynk & Co, the joint venture between Geely and Volvo, do it right, or did Geely’s Volvo do it wrong?

Upward must not be wrong, but from the current point of view, Lynk & Co 09 on many of its own highlights did not speak out, belonging to its label should not be closer to Volvo, but how to shape 300,000 client base better cognition and more accurate understanding.

From a technical perspective, the dismantling of the Lynk & Co 09 does use some Volvo technology, but it does not mean that it has much to do with the Volvo XC90.

From a production perspective, co-platform production is the ultimate direction of the enterprise. The fundamental purpose of producing the Lynk & Co 09 on the Volvo XC90 platform is to save costs, but the brand building, cultural cultivation, and consumer resonance, the Lynk & Co 09 and the age of consumers are far less than the Volvo XC90.

At present, the average monthly sales of Lynk & Co are around 1000-2000 units, and the sales of Volvo XC90 are also in this range, which can explain some problems.

　　Should the taxi concession system be broken?

　　– Implications from the development of the US taxi control system

　　Authors: Xu Kangming, Su Kui

　　In the early 1970s, an anti-government control ideology arose in the United States, which is very similar to some domestic ideological trends today. It believes that government control "rarely does the right thing" and relying on market mechanisms "rarely does the wrong thing". As a model of a free economy, the government restricts the freedom of access to certain industries and does not allow market competition mechanisms to determine prices. The core guiding ideology of deregulation holds that government pricing and industry access systems will inevitably lead to waste of resources and inefficient services, and even belong to administrative monopolies. At the same time, it restricts the choice of service types and price systems for transportation service recipients. Even though some scholars originally suggested that it was the late 19th and early 20th centuries that market failures gave rise to government access and price controls on the transportation service industry, under the strong impetus of this trend of thought, the United States began to partially or fully deregulate many transportation service industries, involving most transportation modes such as aviation, road passenger and freight, rail transportation, and intercity passenger transportation. The taxi deregulation movement experiment was also launched in this wave of free economy.

　　First, the North American taxi deregulation test failed to meet expectations

　　The confluence of political forces out of dissatisfaction with traditional taxi services and "theorists" out of their adherence to the fundamentals of market economy forcibly promoted this deregulation action. In the urban taxi industry, a cycle from regulation to deregulation and back to regulation was dramatically performed. American cities have imposed access and price controls on the taxi industry since the 1920s. Half a century later, more than 20 cities, most of which are in the so-called sunshine zone, that is, cities with rapid economic development, have completely or partially lifted such controls. However, due to the unsatisfactory effect of deregulation, almost all of these cities have resumed access and price controls for the taxi industry.

　　Opponents of taxi regulation argue that the free market allocates resources most efficiently and offers taxi passengers the best mix of prices and services. Therefore, encouraging competition and innovative services is the main purpose of liberalizing taxi market access. Proponents argue that free market access promotes higher service quality and lower prices, and facilitates innovative services. This view was crucial to deregulating the taxi industry. In 1965-1983, 18 cities in the United States and Canada scrapped taxi access mechanisms in order to encourage competition and encourage innovation.

　　At that time, some scholars and experts did not agree that the taxi industry could adopt the principle of free market, believing that the many advantages of the taxi industry brought by relying on market forces would fail in an imperfect market environment, and regulation was a necessary means to correct the market failure. The main views of these scholars are: (1) Taxi is not a general commodity, taxi is a supplement to public transportation, and it is an important public service, especially for some cities with underdeveloped public transportation, and for some special groups (such as the elderly, the disabled, and outsiders) It is an irreplaceable basic service. ( 2) Passenger transportation is an extremely sensitive industry to safety, and regulation is conducive to the implementation of many measures to provide safe travel for passengers; (3) Regulation is conducive to fair and legal competition, such as some urban taxi markets are controlled by evil forces; (4) Regulation is conducive to the implementation of the cross-subsidy mechanism, and taxis under the control mechanism implement the same rate in the entire region to form a cross-subsidy mechanism, that is, peak income subsidizes flat peak, and high-density area income subsidizes low-density areas. If there is no such regulation, the service level of flat peak and low-density areas will decrease significantly, or even not be effectively served; (5) Asymmetric information leads to market failure, and regulation is to solve the information asymmetry existing in the taxi industry, which causes consumers to be disadvantaged; (6) Taxi is a random consumption It is difficult to survive the fittest through market forces. Regulation can reduce vicious competition. Free access will attract a large number of operators and individual operators to enter the market, ultimately leading to excessive supply of transportation capacity and affecting service quality.

　　When the rental control system was relaxed, the number of taxis in these cities in the United States and Canada was oversupplied, and the revenue per driver was greatly reduced after the oversupply. Some cities were unable to maintain minimum income requirements and updated vehicle requirements. Those cities with a relatively large proportion of roadside tenancy quickly resumed the control system in the mid-to-late 1980s. Some cities had more roadside tenancy stations. Due to the oversupply of taxis, the waiting time for taxis was too long, which not only reduced their income, but also affected the efficiency of taxi turnover. Another layer of pressure on the taxi surplus is the price. Drivers constantly demand price increases, pick passengers, refuse to take short trips, "detour", and reduce the quality of taxis. All kinds of bad habits are even more and more serious.

　　Fourteen cities, including Boston, Baltimore, Toronto, Montreal, Vancouver, and Seattle, regained their taxi number control systems, which basically ended the original 18 cities’ attempts to abandon the taxi number control system. Facts and actions once again confirmed the necessity of reasonable taxi control. The remaining cities that persisted for a period of time also partially reapplied the taxi control idea. And even though Washington, D.C., the capital of the United States, which claims not to carry out quantity control, has suffered from excessive quantity, although many attempts to refer to New York’s management of operating rights have failed to control the quantity, Washington has in fact not issued new cards since 2010. In 2014, it was once again proposed to control the current number by 2016, so as to actually implement the management of the number of taxis, but it is a more flexible control mechanism than New York.

　　The problem with taxi services is that they are not well regulated

　　The taxi quantity control system is an important measure to ensure the stable development of taxis based on the characteristics of taxi services. However, if the establishment of a dynamic coordination mechanism for quantity, service quality, price, and driver income is ignored in the implementation process, the taxi market is also prone to various criticisms. The specific manifestations are: (1) quantity shortage, if the adjustment time interval in the quantity adjustment mechanism is too long, taxis are prone to form a shortage of supply and eventually form a regional or peak period taxi hailing difficulties; (2) hindering adjustment, if the market price of taxi operating licenses is too high, it is easy to form interest groups, and interest groups often try to prevent or delay the adjustment of quantity, or try to reduce the number of new taxis; (3) regional differences, quantity control can easily cause taxi services to be concentrated in areas with high demand for taxis, such as downtown commercial Areas with high demand for taxi travel, such as districts, cultural and entertainment areas, and hotels, will have insufficient taxi supply to low-income areas and suburban areas; (4) It is not easy to adjust prices, and the control mechanism often makes it difficult to adjust taxi prices. The taxi price adjustment mechanism requires a hearing to adjust prices. City governments often postpone taxi price adjustments as much as possible. Cities often do not adjust taxi prices for a long time until the price contradiction intensifies before starting to adjust prices. (5) Labor conflicts. Taxi control mechanisms can cause labor conflicts between some drivers without taxi operating licenses and the owners of operating licenses, because these drivers must pay the fee for using the license. When the overall economic situation or taxi market demand is not ideal, economic disputes are prone to occur.

　　The current concession system implemented by "cruise taxis" in China. In 2002, the Ministry of Construction’s "Opinions on Accelerating the Market Process of Municipal Public Utilities" defined the municipal public utilities concession system as "in the municipal public utilities industry, the government grants enterprises the right to operate a certain municipal public product or service within a certain period of time and scope, that is, the concession right." Under what circumstances can the government implement concessions to a municipal public utilities industry? The answer is simple. It must be conducive to the realization of public interests and prevent operators from obtaining the privilege of monopolizing profits. The characteristics of taxi services are that individual citizens and outsiders have very weak service quality monitoring and bargaining power, while taxis are necessary and encouraged to develop travel tools. At the same time, by setting prices, the characteristics of weak bargaining power of individual consumers can be avoided. Whether the service characteristics of taxis are corporate operations or individual carriers, in the end, each rental service demand needs to be completed independently by a practitioner, and the demand is 24/7, regardless of frost, rain, day and night, the demand will exist, and the income of taxi practitioners must be guaranteed before someone is willing to provide services around the clock. Under the premise of taxi price limitation, in order to ensure that taxi practitioners and taxi operators have reasonable income and profits, a reasonable total control must be implemented on the number of taxis in a designated service area.

　　As mentioned above, after the taxi market adopts concessions, if the lack of dynamic quantity control mechanism will cause the contradiction of taxi difficulty, if the lack of dynamic price control mechanism, it will cause the contradiction between taxi driver income and labor, if the lack of service quality control will cause the taxi service level is low. The current domestic taxi market has many problems and needs to be improved and improved, but it is undeniable that in the context of inflation in the past ten years, taxi prices have remained low for a long time (some cities have not even adjusted prices for 18 years), and many governments have hardly dared to get involved in taxi price adjustment. In recent years, due to factors such as oil prices, labor costs, traffic congestion, and labor conflicts, taxi prices have had to be adjusted in small strides. Taxi as a public service has basically maintained a stable, low-cost, and reliable transportation service. This is due to the hard work of employees and the government’s price control. Some current reports and commentaries demonize the taxi industry, arguing that it is unfair and rational to break the taxi concession system, and ignoring the valuable experience gained from international reform practices.

　　III. The Internet promotes the further improvement of taxi control

　　Finally, looking at the current regulatory status of taxi concessions in the United States, after the Internet companies Uber and Lyft launched Internet rental services and profitable ride-sharing platforms, has the United States called for and is breaking the taxi concession mechanism? The answer is no! Although all parts of the United States are setting various conditions through legislation to regulate Internet taxi-hailing software companies to engage in Internet rental services for cruise taxis and rental taxis, as well as gradually standardizing profitable ride-sharing platforms that are in conflict with traditional taxi operations, the United States has not called for breaking the taxi concession mechanism. Of course, many cities have also reviewed the impact of the Internet on traditional taxis when formulating Internet rental control regulations, and optimized the control system (such as requiring drivers to use taxi-hailing software compulsively, improving the price mechanism, reducing license fees, etc.). Uber Uber has expanded to more than 250 cities around the world under the impetus of capital forces, and these cities have not proposed to break the taxi concession mechanism. And some cities that were not regulated in the past are still joining the ranks of regulation.

　　At the moment when the characteristics of taxi services have not fundamentally changed, a taxi concession mechanism is necessary. In the Internet age, especially when taxi-hailing software companies have absolutely occupied the online leasing market under the impetus of capital power, whether a taxi concession mechanism is still necessary, the answer is necessary. This is the guarantee mechanism to maintain that citizens can continue to enjoy low-priced, stable and fair passenger transportation services. However, the right to operate a taxi under the concession mechanism should not become a hotbed of rights and capital rent-seeking, and the right to operate a taxi should not be alienated into an investment asset and usurp monopoly income. This needs to be reformed and improved. In addition, to alleviate the problems of difficulty in taxi hailing, poor service, and single form, it is necessary to improve the control mechanism, rationally locate the function of taxis, dynamically evaluate the number and price of taxis, increase the number of cruising taxis in a timely manner, and vigorously develop legal rental and ride-sharing. The impact on the Internet should also be continuously observed. Only changes in the service characteristics of taxis can determine the reform of the control method. The sticks of the media, experts, and misguided citizens are in the wrong place. (Xu Kangming, Su Kui)
