China’s self-developed shield machine for the world’s largest diameter high-speed rail-Chongtai Yangtze River Tunnel "Pilotage" completed the cutter head welding.

China Railway Shanghai Bureau Group Co., Ltd. introduced that recently, the shield machine "Pilotage" of Chongtai Yangtze River Tunnel, the world’s largest diameter high-speed rail shield machine independently developed by China, completed the cutter head welding and will be used for the construction of the new Shanghai-Nanjing-Hefei high-speed rail Chongtai Yangtze River Tunnel. The tunnel connects Chongming District of Shanghai and Taicang City of Jiangsu Province, with a total length of 14,250 meters and a design speed of 350 kilometers per hour. See ↓

The cutter head of "Pilotage" shield machine has a diameter of 15.4 meters and a total weight of 440 tons. After the cutter head is welded, the cutter head will be subjected to ultrasonic flaw detection, flatness, roundness and cutter head painting for all-round "physical examination" to ensure the smooth combination of the cutter head and the main engine.

Chongtai Yangtze River Tunnel is the control project of Shanghai-Nanjing-Hefei high-speed railway, and it is also the project with the longest contract period. The tunnel connects Chongming District of Shanghai and Taicang City of Jiangsu Province, with a total length of 14,250 meters and a design speed of 350 kilometers per hour. It is a single-hole and double-line design, and it is the world-class high-speed rail cross-river tunnel project with the highest construction standard, the longest driving distance and the largest scale. Chongtai Yangtze River Tunnel is constructed by cut and cover and shield method.

It is reported that the "Pilotage" shield machine will start from No.3 well in Chongming District, Shanghai, and tunnel 11,325.5 meters across the Yangtze River to No.2 shaft in Taicang City, Jiangsu Province. The shield construction has the characteristics of large section, high water pressure, complex geological conditions, long shield tunneling distance and sensitive environment.

Shanghai-Nanjing-Hefei high-speed railway is the eastern route of Shanghai-Chongqing-Chengdu high-speed railway and an important part of the national "eight vertical and eight horizontal" high-speed railway network along the Yangtze River, which undertakes the transportation of the main road network passenger flow along the Yangtze River and the coastal and Beijing-Shanghai passages directly to Shanghai. After the completion of the project, a fast new channel will be built between Shanghai metropolitan area, Nanjing metropolitan area and Hefei metropolitan area, which is of great significance for optimizing the layout of railway network along the Yangtze River, serving the coordinated development of the Yangtze River Economic Belt and promoting the high-quality integrated development of the Yangtze River Delta.

Baojun Yueye/Yueye Plus is listed for less than 100,000 yuan and has four seats.

Wuling and Baojun, two brothers, are very active in the pure tram market. Unlike many car companies that make compact cars and SUVs, their cars are particularly popular. The family recently went public, including the 2024 Baojun Yuehe.

Bao jun yue ye Plus

Among the Yueye family listed this time, Yueye Plus is obviously the one that attracts more attention. Because this is a brand-new model with four complete doors, it is more in line with the demand of our domestic consumers for new cars. Even a personalized car can’t escape the category of daily use.

Yueye Plus is still positioned as a small car, but its body size has increased significantly, with a length of a little less than 4 meters, specifically 3996mm and a wheelbase of 2560mm, which is 615mm and 450mm higher than that of Tiffany Ting. If the tailgate is counted, the number of cars will increase from three to five. It is easy to distinguish in appearance.

This has also brought about an obvious increase in the space inside the car. Four people can sit down seriously, and there is still room for luggage in the trunk. This is very practical for our traditional Chinese family.

There are two versions in the whole system, the flagship version and the Zhizun version, with a guide price of 9.38-103,800 yuan, which is already the price level of an ordinary household compact plug-in car. Of course, the corresponding configuration has also changed. The battery capacity has become higher, reaching 41.9kWh, which can achieve 401km battery life under CLTC standard. At this price, such endurance performance is reasonable.

On the configuration level, the low-profile flagship version is equipped with front and rear radar, cruise control, keyless entry, external discharge, automatic headlights, induction wiper, electric folding/heating of exterior rearview mirror, electric adjustment of main driver’s seat and automatic air lift.

Wisdom Edition adds L2 driver assistance, transparent chassis and driving recorder. Among them, the most important ones are intelligent driving, high-speed navigation system, automatic lane change, entering and leaving ramps, tracking and reversing, remote parking and so on. The difference of10,000 yuan is actually mostly in the smart driving.

2024 Baojun Yueye

The new Yueye, that is, the two versions that existed before, has been updated this time, mainly in some details, and has remained basically unchanged. The most intuitive change is the change of wheel shape. It’s hard to say which one looks good, the old one or the new one. In addition, the color of the car has also increased three models, namely, Yunhai White, Mountain Fog Grey and Xiaguang Blue, with more choices.

The front central armrest box has been added to the interior of the car, which should be praised, especially for long-distance driving. It can also increase storage space. However, the price has also increased in 1000 yuan, which is somewhat smaller.

Generally speaking, Bao Junyue has not changed much, but the highlights are still those, such as the only intelligent driving ability at the same level, 50kW motor, 303km battery life, intelligent car system and good functional configuration.

As far as the price range of 80,000-90,000 is concerned, it is a very reasonable price with such performance and personalized body. But after all, it is a play-oriented model, and the sales volume is not much higher.

Who are competing products?

To say that the competing products of Baojun Yueye are actually not easy to find, most of them are ordinary family cars at this price, such as,, geometric E fireflies. BYD’s is relatively close.

But because of this, Yueye’s personalization is the first choice for many users who don’t like traditional cars or SUV models. They are usually young-minded, maybe they just graduated from college, or they are the second car at home. I don’t care much about battery life, space and face. Conversely, if there is a need for a family car and you want to have a long battery life, then Yue will be excluded from the first step.

Yueye Plus fills this gap well and is suitable for young consumer groups who are not bound by traditional ideas, pursue individuality and have certain family travel needs. They prefer to have the ability to travel by 3-4 people occasionally, and the battery life should not be too long. There is a little more space and go on road trip is more convenient. The budget of around 100,000 yuan is not expensive compared with Tiffany Ting.

Judging from the price and body parameters, it is a pity that neither Yue nor Yue Plus can apply for Shanghai brand for free in Shanghai. At present, among Baojun’s new energy sources, only it meets Shanghai’s free Shanghai brand application standard. Of course, in most parts of the country, you can enjoy the green card preferential policy.

Then there is smart driving, which is a major direction of the current "volume" of new energy vehicles. Whether it is Bao Junyue or Bao Junyue Plus, it is almost the strongest existence of 100,000 levels. The price to pay for this is also very small, about 10 thousand yuan.

This time, the price of Baojun’s Yueye Plus is quite surprising, which is not much higher than that of Tiffany Ting. Not only is the car body lengthened, but the battery is also bigger, making it easier to use the car. Whether it is Bao Junyue or Bao Junyue Plus, they all have quite individual body design, and their performance and configuration are all ok. As said at the press conference, smart driving is their advantage. It is really rare to achieve high-speed NOA at this level.

All localities have stepped up efforts to support private investment and activate the "engine" of economic growth.

CCTV News:Private investment is the "engine" of economic growth. In the first half of this year, the growth rate and the proportion of private investment in the overall investment declined. In order to encourage and support private investment, in addition to the 17 policies and measures issued by the National Development and Reform Commission, various localities have also issued policies to increase support for private investment. Private investment in many fields has been increasing, and private investment confidence is gradually recovering.

Recently, various parts of China have issued relevant policies and measures to increase support for private investment, and all localities have actively explored new, practical and hard measures to promote the high-quality development of private investment. By creating a good business environment, broadening the track of high-quality investment and breaking down hidden investment barriers, private capital can be assured to invest well.

Shanghai has introduced 20 policies and measures to support private investment in major projects, reduce links, time and efficiency for private investment projects, reduce the cost of land for enterprises and implement preferential tax and fee policies.

Gu Jun, Deputy Secretary General of Shanghai Municipal Government and Director of Municipal Development and Reform Commission:Resolutely break down invisible barriers, further emphasize areas outside the negative list of national market access, support private enterprises to enter equally according to law, and carry out investment according to law. Encourage private capital to actively participate in 102 major projects planned by the state in the 14th Five-Year Plan and major projects planned by Shanghai in the 14th Five-Year Plan. Private enterprises participate in the design, construction, raw materials, facilities and equipment supply of major projects, and are treated equally in bidding.

In order to boost the confidence of private investment, Guangdong Province introduced four types of projects, including infrastructure, industry, scientific and technological innovation and social livelihood, with a total of 101 demonstration projects and 56 application scenarios, to attract private capital to participate.

Ye Zilin, Deputy General Manager of Guangzhou Daxin Cultural and Creative Development Co., Ltd.:With the government setting up a stage and enterprises singing opera, we can connect with the participating enterprises with relevant technologies on a higher platform, which can empower us more.

Since the beginning of this year, confidence in private investment has gradually recovered. 1— In May, the proportion of private investment in manufacturing investment reached 94.3%, and private investment in many fields continued to increase. In Wuhan, Hubei Province, the air-conditioning intelligent manufacturing base with a total investment of more than 3.4 billion yuan and an annual production capacity of 6 million sets was put into production at the end of March. The annual R&D investment of this enterprise for intelligent manufacturing accounts for nearly 5% of the total revenue.

Li Dongsheng, Chairman of TCL:Dare to invest in the future. In 2022, we added 68 billion yuan in investment, and this year we have planned another 36 billion yuan in investment.

Although the growth rate and the proportion of private investment in the overall investment have declined in the first half of this year, private investment has shown many bright spots in some areas. In the first half of this year, private investment except real estate development increased by 9.4% year-on-year, private investment in manufacturing increased by 8.4%, and private investment in infrastructure increased by 15.6%, showing strong investment confidence and investment motivation.

As the "engine" of China’s economic growth, private investment plays a key role in creating employment opportunities and enhancing economic vitality. With the implementation of national and local measures to support the development of private investment, the endogenous motivation of private investment will be effectively stimulated and private investment will achieve high-quality development.

Which is the best driving platform? Which is better, e-driving and Didi driving?

At present, the top ten driving companies are e-driving, Didi driving, hitchhiking, (| |) driving, Ai driving, micro driving, etc. Among them, e-driving and Didi driving are relatively well-known and are also among the best in the driving industry. Many friends who want to join the ranks of driving are hesitant and do not know which driving platform is better. Today we will discuss the situation of e-driving and Didi driving in detail, and give some guidance and suggestions.

Which platform is better?

E-driving status quo: At present, more than 100,000 drivers and 500,000 users have registered, and the business covers 200 cities. It is the first driver platform that has been deployed and entered the market. It has certain advantages in hardware, service system, word-of-mouth and brand. User experience is the hottest, coolest and most practical mobile client side.

Didi driving status quo: a one-stop travel platform including taxis, special cars, express trains, hitchhikers, chauffeurs, and buses. The diversity of services allows more users to choose Didi driving, and it also has many advantages such as driver resources and platform big data, which has won a certain reputation.

Love the status quo of chauffeur driving: China’s chauffeur driving industry is a fast, safe and reliable professional drunk driving service. Starting at 38 yuan is cheaper than a taxi, but it is not as popular as the first two.

Micro Driver Status: It is an application that solves various needs such as drunk driving, business driving, long-distance driving, renting a car, and driving test sparring.

In general, each major driving platform has its own advantages, e-driving and Didi driving have more advantages. Let’s analyze it in detail below.

Which is better, e-driving and Didi-driving?

1. As for how much money Didi and e-driving can earn a month, according to the driver’s report, most of the orders for part-time drivers at night are after ten o’clock in the evening, and one order is more than 100. You can earn about 150 yuan for two or three orders a night, and the driver can earn 2000-3000 yuan a month. No problem.

2. Didi driving and e-driving platforms are a problem. The driver also mentioned that if you drive 10% -20% for a single drive, Didi will have driver points. If the cancellation is greater than 20%, the corresponding points will be deducted (12 points a year), and the e-driving platform will even give the offending driver a ban.

3. Platform scheduling rules. Both platforms adopt the rules of customer self-service or system dispatch. The client side can display the information of the nearest driver. Select one of them or place an order with one click to call the driver for door-to-door service. But the system dispatch requires the customer to place an order on behalf of the driver and make an appointment according to the time of the customer’s appointment.

4. Platform charging standards. Since the charges vary slightly from place to place, in general, the charges for e-driving will be higher. If you want to drive part-time, you can choose e-driving. For details, please click (Didi driving charging standards) or (e driving charging standards) to view.

5. Liability for driving accidents. Didi driving platform liability protection of up to 3 million yuan per order brings greater protection to drivers and passengers when contemporary drivers have accidents. E driving platform liability insurance maximum compensation 2 million.

Wang Zhigang, Minister of Science and Technology: China deploys vaccine research and development according to five technical routes.

CCTV News:The State Council Information Office today (June 7) released the white paper "China Action against COVID-19 Epidemic" and held a press conference to introduce the white paper.

Wang Zhigang, Minister of Science and Technology, in response to a question from a reporter in Reuters, pointed out that since the outbreak of the epidemic, all countries have paid close attention to the vaccine problem. The white paper also includes the related contents of scientific and technological support against epidemic, such as how to combine scientific research such as drugs and vaccines with clinical first-line treatment practice, and how to use big data and artificial intelligence to support against epidemic. As far as the vaccine itself is concerned, judging from the understanding of human response to the epidemic in history, the vaccine is still the fundamental strategy for us to defeat COVID-19 virus at present. All countries put the development of vaccines in a very important position in the fight against COVID-19. But at the same time, we should also see that vaccine development is a very rigorous and complicated scientific activity, which is very difficult and has a long cycle. At the same time, because it is a scientific research, it also has great challenges and uncertainties. Some scientists compare the rigor of vaccine development to an accurately rehearsed dance, rather than an impromptu performance that can be displayed after the curtain is lifted. Therefore, safety, effectiveness and accessibility must be placed in a very important position in vaccine development. Vaccine development has played an important role in human history, but some vaccines have also gone through some detours.

疫苗成功的标志,最重要的是坚持安全、有效和可及。从科学研究上讲,疫苗研制一般要经过病毒分离、实验室疫苗构建、细胞试验、动物试验、临床研究,然后才是规模化生产,最后要经药监部门注册批准才能上市应用。我国按照五条技术路线部署疫苗研发,包括灭活疫苗、腺病毒载体疫苗、重组蛋白疫苗、减毒流感病毒载体疫苗以及核酸疫苗。在疫苗研制过程中和今后的临床试验应用,这两个方面都要加强国际合作。前期我们在整个疫苗研制过程中,都开展了很多国际合作,中国的科学家和其他国家的科学家,都是为了应对疫情,都希望在卫生健康方面为人类命运共同体作出贡献。下一步,中国疫苗如果完成了研制和临床试验后,可以达到应用的时候,我们会认真落实国家主席习近平在第73届WHO大会上的承诺,把它作为公共产品向全球提供。

It’s snowing, and the circle of friends of the ancients is like this.

  Yuan an lies in snow

  The Snow Lion Map (partial) Yu Ming

  "Painting Emperor Gaozong’s Imperial Pen after Jiawu Snow" Qing Dong Gao

  Fish Selling in Snow River (Partial) Li Dong in Southern Song Dynasty

  Every winter, we will see many different forms of snow, especially this year’s Winter Olympics, and various competitive competitions have opened up our "new world of ice and snow". As a modern person, the process of enjoying the snow is naturally to take photos, shoot videos and send friends, so what will the ancients with big brains do in snowy days? We might as well travel through the circle of friends into ancient paintings and books, and enjoy the snow that has fallen for thousands of years with the ancients.

  "Ice mound" and "snow melting" … … Not enough, properly pile up a zoo.

  As the mascots of the Winter Olympics, the ice pier and the snow rongrong burst into red overnight, becoming a veritable top stream of the Beijing Winter Olympics, especially the ice pier, which can be described as "one pier is hard to find" whether online or offline. Coincidentally, at this time, there was heavy snow in many cities in China, so netizens who couldn’t buy ice piers built ice piers with snow. Many netizens shouted "creative" in the comment area.

  In fact, it is not an innovation for modern people to use snow mounds and ice mounds. On the contrary, it is a trend of "retro", because in ancient snowy days, ancient people will also play this kind of game full of childlike interest. But instead of building a snowman, they are mainly animals, such as lions. According to "Dream of Tokyo", "In a rich family, if it meets snow, it will have a feast, make snow lions and install snow lanterns to celebrate the old days." Yes, you are right. The ancients played with snow in such a grandiose way. Simple snowmen don’t pile up. If you want to pile up, pile up a snow lion and come out of town.

  Not only rich people like to pile snow lions, but even the palace in the Song Dynasty is full of interest in snow lions. In the Southern Song Dynasty, Zhou Mi recorded in detail the basic process of enjoying snow lions in the palace at that time: "In the back garden, large and small snow lions were brought in, decorated with golden bells, and made snowflakes, snow lanterns, snow-capped mountains and the like." In the imperial palace of the Song Dynasty, snow lions, large and small, should not only be piled up, but also be adorned with jewelry, such as hanging golden bells around their necks and wearing colorful silk threads. In order to meet the occasion, in addition to snow lions, the ancients also piled snow mountains, snowflakes, snow lanterns and so on. Among them, the "snow lamp" is reminiscent of the "snow melting" of the Beijing Winter Olympics. It is a kind of lamp made of snow, which has the same effect as the image of a red lantern with snow hanging on it, and looks like it is moving and moving.

  But then again, why did the ancients love lions so much? Is the snow lion piled by the ancients the same species as the lion that we modern people see in the zoo?

  As early as the Han Dynasty, in order to establish diplomatic relations with the Great Han Dynasty, the interest country paid tribute to the lion and Fu Ba, and called them "Swiss beasts". Gradually, the image of the lion has also penetrated into the daily folk life of the ancients. The most typical one is that a large number of "stone lions" appeared in ancient times, because the ancients thought that stone lions were spiritual and could guard all directions. Yu Shinan, a scholar in the Tang Dynasty, wrote a poem "Ode to the Lion", in which he mentioned that the lion was a sacred animal. Later, Li Shizhen, a medical scientist, called the lion "the leader of many animals". It can be seen that the lion has always been a symbol of good luck, and it is also a manifestation of identity in the palace. As for the snow lions piled up by the ancients in snowy days, they are generally like stone lions: first, stone lions are more common, and the ancients don’t have to open too many brain holes; Second, the image of the stone lion is relatively stable, and it is not easy to collapse after stacking!

  After the Qing Dynasty, the ancients no longer focused on piling snow lions, but began to pile elephants and horses. In the Qing Dynasty, wu zhen Machinery recorded in Volume 14 of the Collection of Keeping Ji Zhai: "Every time it snows in winter, it piles up into lions and elephants in hall of mental cultivation’s court, and Chen Yong is often invited to sing. Ganlong Renshen, Yiyou, combined with snow lion and snow elephant. Jiaqing Wuyin, another pile of lying horses, is divided into east and west, and there are poems linked with the Imperial Palace Hanlin. " When the snow lion, the snow elephant and the snow horse are piled up, the emperor and the Hanlin scholar in the palace will also use this as the theme to recite poems and compose poems. In the Ci of Bianjing Palace written by Yan Jizhou during Guangxu period, there are poems describing the snow appreciation and entertainment in the palace, such as: "Ruixue is colorful in the sky, and lions are piled up in front of the stage."

  It can be seen that in snowy days, the ancients also loved mascots to the extreme.

  Snowy days are still inseparable from the word "eat and drink", even Bunny Bunny.

  It’s enjoyable to use the snowmobile mascot, but it’s a little cold after all, and when it’s cold, you will be hungry, so the ancients’ favorite thing after playing with snow is to have dinner. On a snowy day, the most classic is the a suggestion to my friend liu written by Bai Juyi in the Tang Dynasty: "there’s a gleam of green in an old bottle, there’s a stir of red in the quiet stove. There’s a feeling of snow in the dusk outside, what about a cup of wine inside?? " On a snowy evening, the newly brewed rice wine at home has not been filtered, and there is a layer of green bubbles on the wine surface, and the small stove made of red mud is ready, just waiting for a good friend to drink!

  Some people have an appointment for dinner, and naturally some people will come to eat rice. The ancients who paid attention to etiquette can’t come to eat rice empty-handed, right? Under normal circumstances, the ancients would bring some good wine or some snacks to eat, but Lin Hong’s cookbook "Shan Jia Qing Gong" in the Southern Song Dynasty recorded one thing, and the gift he brought to visit was really special: "When you visit Wuyishan Six Songs, you will get a rabbit in snowy days, and no one can control it. Shi Yun: Only a thin batch is used in the mountains, and the wine, sauce and pepper are abundant. Use the air furnace to cook Azakami, use less water than half a cup, and after the soup rings, use chopsticks for each, so that the soup can be cooked and cooked, so that it can be served with juice as appropriate. "

  Lin Hong visited his friends on a snowy day, but he actually caught a rabbit on the way, so this rabbit was the gift of his visit. But there was no cook in the mountains, so Lin Hong’s friend thought of a way. He said to Lin Hong, "Everything can go into hot pot! I’ll prepare some dip, and today we’ll rinse the rabbit hot pot! " Sure enough, in the eyes of foodies, rabbits are not pets, but food.

  In addition to washing meat, the ancients especially liked to eat fish in snowy days. In the Palace Museum and the Metropolitan Museum of Art in New York, there is a picture of a round fan, the former is called "Fish Selling in Snow River" and the latter is called "Fish Buying in Snow Bridge". In the snow landscape map, buying and selling live fish, which seems to be full of fireworks, brings interest to the picture. Although many scholars think it is used to reflect the ideal spiritual world of literati and fishermen, it also confirms the fact that the ancients like to eat live fish in snowy days. Not only the ancients in the Central Plains loved to eat live fish in snowy days, but also the nomadic people in the north. They would dig ice holes in the frozen rivers and lakes in winter to catch big fish. A kind of fish hook used by the Khitan people to hook fish was unearthed in Yemaotai Liao Tomb, Faku, Liaoning Province. It has a sharp hook tip, a long hook body and a wooden handle, which is an artifact used to "hook fish with ice".

  After eating meat and drinking wine, the ancients also drank some tea to scrape oil in snowy days. However, how can the ancients who have always had a big brain hole only cook tea so honestly? Yes, they’re up to something again. In the eyes of the ancients, normal mountain springs could no longer satisfy their pursuit of snow and elegance, so they targeted snow.

  In the Ming Dynasty, Gao Lian once said in "Sweeping Snow and brew tea Playing with Paintings": "Tea cooked with snow tastes clearer, and it is also a river for half a day. Free from dirt, it’s enough for you to sip it. " It seems that the ancients not only used snow brew tea in snowy days, but also took snow from plum blossoms, orchids and pines. It feels that as long as they drink this cup of snow-cooked tea, they can have the cleanliness of snow, the pride of plum blossoms, the elegance of orchids and the integrity of pines. This is clearly our modern popular "concept tea"!

  It is easy to get mad in snowy days. Zhang Dai collected wonderful jokes about snowy days.

  After playing with snow, eating rice and drinking tea, it is naturally necessary to "pretend". We modern people often get some gimmicks to make a circle of friends in the snowy days. Some people practice yoga in the snowy days, some people wear Hanfu to the Forbidden City, and some people lie in the snowy days and imitate idol films to take pictures … … The "artificial" in the snowy days of the ancients is naturally very special and can be called performance art.

  For example, in the Song Dynasty, there was a man named Wang Jiang who was wandering around Chen Zhou (now Huaiyang, Henan). Although he was a tramp, there were many fans at that time, and scholars like Su Dongpo and Su Zhe were his loyal fans. In addition to his bohemian love of freedom, this Wang Jiang has a special function, that is, in snowy days, he will bury himself with snow, and then melt it with a hot air. After the snow melted, Wang Jiang was fine and continued to wander while drinking. It is rumored that people who saw this scene at that time were greatly shocked.

  Perhaps this is not the most wonderful thing in a snowy day. In the snowy day, Zhang Dai, a scholar in the late Ming Dynasty, not only went to the pavilion in the middle of the lake to see the snow by himself, but also wrote a small composition. He also did a great thing, that is, in the first volume of the book "Sailing at Night", he opened a column called "Astronomy Department Snow Frost" to collect wonderful jokes about snowy days. Among them, we are familiar with "catkins due to the wind", "Xun Mei through the snow", "Reading in the snow" and "biting snow and swallowing blankets", which are quite normal. The rest of the jokes can only shock us modern people.

  For example, the joke "I want to go to the immortals" is said to be the yue people in Wang Mian. When it is snowy, they are not afraid of the cold and go barefoot to climb the furnace peak. After looking around, they shouted: "Heaven and earth are all made of white jade, which makes people feel clear and clear, so they want to go to the immortals!" Like Wang Mian, there is also a "fairy middleman" who likes to cultivate immortals. It is said in the article that Wang Gong of Jin once walked in the snow wearing a coat with crane hair. When Meng Xu saw it, he made a commercial compliment to him: "Oh! You are really a fairy! "

  There is also a road flyover named Tiejiao, who is neither afraid of cold nor diarrhea. On snowy days, he loves to walk barefoot in the snow. When he is happy, he will recite "South China Autumn Water" loudly, then pick some plum blossoms and put them in his mouth to chew. When he feels a little dry, he will get some snow to swallow together. In this regard, he explained: "I want to soak this cold fragrance into my heart!" In this way, I am as fragrant as plum blossoms and as clean as snow! "

  We don’t know whether these action art became immortals or not, but one action art got an offer on a snowy day. The name of this joke is very poetic, called "Lying Snow", and the protagonist is Yuan An, a famous minister in the Eastern Han Dynasty.

  It is said that it snowed heavily in Luoyang one year, and everyone else went out to beg for food, except for the snow in front of Yuan ‘an. When Luoyang made a door-to-door inspection, he thought that Yuan An had died of cold and hunger, so he asked people to sweep away the snow in front of his door and then go into the house to have a look. After entering the door, Luoyang Ling and his entourage found Yuan An lying upright as if he were not dead, so he asked Yuan An, "Why don’t you go out?" Yuan An replied, "In this snowy day, everyone is hungry. We shouldn’t disturb others. I’ll lie down for a while … …” As soon as this is said, the pattern is there: it is not easy for people to keep moral integrity when they are hungry and cold! Luoyang made Yuan An a virtuous man, so he named him filial piety.

  Since then, Yuan An’s story of sleeping in snow has actually become a Millennium super IP (intellectual property, which is extended to be a general term for famous cultural creation). Not only do poems like to use this story, but scholars also like to add this element to their snow landscape paintings. Perhaps Yuan An himself didn’t think that a heavy snow actually changed his life.

  After brushing the circle of friends of the ancients in the snowy days, I must give the ancients a compliment. They are really good at playing! However, for all kinds of "playing" of the ancients, we modern people should remain sober and rational, only taste the ancient meaning, and can’t blindly imitate it. After all, we don’t have super energy like the ice pier!

Which cities have robbed 1.08 million new energy automobile enterprises?

There are more and more green cars on the road.

Take Shanghai as an example. In 2023, the number of new energy vehicles in the city reached 1.288 million, ranking first in the world. In 2016, this number just exceeded 100,000, an increase of nearly 12 times in seven years.

Counting the history, it has been ten years since the first round of explosive growth of new energy vehicles in 2014.

In 2014, stimulated by the intensive subsidy policies of the central government and local governments, the demand for new energy vehicles was greatly released, which ushered in both production and sales. According to the statistics of China Automobile Association, in 2014, 78,499 new energy vehicles were produced and 74,763 vehicles were sold, up 3.5 times and 3.2 times respectively over the previous year.

The development of new energy vehicles has also brought economic benefits to their cities.In the past ten years, countless cities have come to an end. More than 10 cities, including Shanghai, Chongqing, Shenzhen and Xi ‘an, have set the goal of building a "new energy automobile capital", hoping to get this big cake first.

So in the past ten years, which cities have successfully embarked on their own development path of new energy vehicles? Based on corporate big data, we sketched out a ten-year urban competition record.

Ten Years of Enterprise Big Data: Counting Four Major Urban Industrial Clusters

To build a new energy automobile industry, one of the most important goals is to form industrial agglomeration, so as to achieve scale effect. We selected four major urban agglomerations with the largest concentration in China’s new energy vehicle industry, and further analyzed 62 cities in the Yangtze River Delta region, Pearl River Delta region, Beijing-Tianjin-Hebei region and Chengdu-Chongqing region.

According to the industrial database of CBN New First-tier City Research Institute, from the latest data of new enterprises such as "high-tech enterprises", "small and medium-sized scientific enterprises" and "specialized and special new enterprises",By 2022, there were 5,764 new enterprises related to new energy vehicles in the four industrial zones.

Based on the industry classification algorithm, the database matches enterprises to all segments of the new energy automobile industry chain, in which enterprises can be matched to three major industries according to the upstream, downstream and downstream: auto parts, vehicle manufacturing and service and application.

In order to better compare the different development directions of cities in the three major industries, we calculated the median of "total registered capital of new energy vehicle enterprises" in 62 cities in the three major industries, which were 947 million yuan, 297 million yuan and 735 million yuan respectively. When we calculate and compare the total registered capital of the three major industries in each city, we can see the industrial distribution characteristics of each city, thus calculating the main industries in the direction of new energy vehicles. For example, the total registered capital of new-type enterprises of "service and application" in Shanghai is 11.561 billion yuan, which is 16 times of the above median; However, the total registered capital of new enterprises related to "auto parts" and "vehicle manufacturing" in Shanghai is only 12 times and 13 times of the above median. Therefore, "service and application" can be considered as the main industry of new energy vehicles in Shanghai.

In order to compare cities better, we spread these data on the map. The main industries in each city are distinguished by different colors, and the total registered capital of emerging enterprises is represented by the size of a circle. It can be found that,The Yangtze River Delta urban agglomeration has more cities with new energy vehicles, and its geographical coverage is also wider.

In addition, among the 62 cities, 25 cities are mainly located in the downstream service and application industries, including Guangzhou, Shanghai, Shenzhen and Chengdu, with the largest number of cities. The main industries in 17 cities are the upstream auto parts industry, including Zhenjiang, Yangzhou and Taizhou. The main industries in 20 cities are the automobile manufacturing industry in the middle reaches, including Beijing, Tianjin and Changzhou.

Then if we add the time dimension, what about the changes of industrial clusters in four major cities from the span of ten years?

We calculated the annual growth rate of the number of new enterprises in industrial clusters in cities compared with 2013, and found that,"Automobile Manufacturing" and "Service and Application" located in the middle and lower reaches of the industrial chain have always been the development focus of the Yangtze River Delta region and Beijing-Tianjin-Hebei region in recent ten years. Comparatively speaking, the Pearl River Delta region has made greater efforts to develop the service and application industries, while Chengdu-Chongqing region has made greater efforts in the vehicle manufacturing industry.

The battle for "the capital of new energy vehicles": Who will end up? Who won?

In the battle for new energy automobile cities, cities have tried their best: some cities have made great efforts to develop with the help of their huge consumer market; Some cities actively promote industrial transformation and upgrading based on local industrial characteristics; Some cities tap the advantages of resources to attract investment.

So which cities won in this competition? Where did you win again? Judging from the available public data,Among the top cities of new energy vehicles, the top three are Xi ‘an, Changsha and Shenzhen, and the top three are Shenzhen, Liuzhou and Shanghai.

Capital never sleeps. In the face of new economic growth points full of infinite possibilities, in the past ten years, the new energy vehicle market has been surging, and many cities have also made efforts to compete for the "capital of new energy vehicles", and the industrial battle has continued to start. We look forward to the future new energy automobile industry, adhering to the concept of innovation and sustainability, and developing healthily and vigorously.
