The population flow has changed again!Recently, the population data of each province has almost come out, and there are new changes.An obvious change in the population trend is that the first-tier metropolitan areas with population growth have seen reductions one after another.The first is the Beijing-Tianjin-Hebei metropolitan area. Following the negative growth of 298,400 in 2021, the scale of population loss will expand to 423,000 in 2022.Among them, the population of Beijing decreased by 43,000, the population of Tianjin decreased by 100,000, and the population of Hebei Province decreased by 280,000.If this rate is reduced, the entire Beijing-Tianjin-Hebei region will have a net outflow of 3 to 4 million people in 10 years, or even more.There is also the Yangtze River Delta metropolitan area. Last year, the population increase of the entire Yangtze River Delta was only 470,000, which fell below 1 million for the first time in 10 years, setting a record low.The net increase in population in Jiangsu Province has also been reduced by half from 280,000 to 100,000.Zhejiang's net population increase from 720,000 to 370,000 was also halved.Shanghai has experienced direct negative growth. The permanent population has decreased from 24.89 million to 24.75 million, which is the largest population reduction in 10 years.As a highly economically active area, the Yangtze River Delta has always been attractive for its population. But even in a big city like Shanghai, the trend of population loss has begun to appear in recent years.What are the trends in population mobility?One is the internal migration of metropolitan areas.For example, in the Yangtze River Delta metropolitan area, the population flowing out of Shanghai came to Anhui. The net population increase in Anhui is increasing year by year, with a net increase of 140,000 last year.The second is the migration from first-tier to second-tier urban circles.Last year, the net increase of Chongqing's population increased by 77,000, the net inflow of population in Jiangxi Province was 94,000, and the net inflow of population in Inner Mongolia Autonomous Region was 65,000.The situation is similar in Chengdu, where the population will increase slightly from 828,000 in 2021 to 842,000.Data that votes with your feet is often the most powerful.The attractiveness of the metropolitan area is not as strong as before. With the reshuffle of population mobility, the second-tier provincial capital cities have risen.Why do many people want to go to second-tier cities?I think there are two reasons.1. The cost of living in first-tier cities is too high.Let alone buying a house, just raising a baby can drain people dry.If you want baby chickens and engage in various trainings, it is possible to spend hundreds of thousands a year.Previously, a child-rearing researcher had done statistics, and if a child was to be brought up to adulthood, the first-tier cities would start with a million. How many ordinary families can afford this cost?2. Driven by industrial migration.Except for a few such as Huawei who moved to Dongguan, and the surrounding urban agglomerations, except for the nearby transfer of low-end manufacturing, high-end industries will not choose the surrounding metropolitan area.Because these surrounding urban agglomerations have no other advantages other than the proximity of logistics, and they have not formed an industrial chain. Like Hebei and Tianjin, Beijing's industry has been transferred, but they can't take over.Looking back at the current second-tier cities, they are very friendly to landing companies. Whether it is policies or business environment, they are very similar to the early first-tier cities.First of all, many second-tier companies are very willing to invest in attracting investment, especially in high-end industries. The surrounding metropolitan areas do not have this advantage to compete with second-tier companies.You can see that BOE invested tens of billions in Hefei. At that time, the Hefei government took out its wealth to invest in BOE shares. In addition, there were huge land and tax incentives.There are also some strong second-tier cities that take the lead in developing emerging industries and directly compete with big cities for industries.For example, Hangzhou High-tech Zone introduced a group of top high-tech enterprises such as Geely Group and Hailiang Group through the investment promotion of the industrial chain in the early years, and is committed to the research and development of top core technologies such as artificial intelligence, cloud computing, big data, and the Internet of Things.It also took the lead in building a large health industry cluster. Today, half of the world's top ten pharmaceutical companies have invested in Hangzhou Economic and Technological Development Zone.What if there is no industrial chain in the second-tier cities? Then make one and vertically integrate the entire industrial chain.Weihai High-tech Zone, for example, customized a laser printer industrial park covering an area of 6,000 mu for the HP industry chain. At the same time, it customized supporting services such as production, R&D, testing, and certification for the development of the industry chain, and finally introduced the United States Hewlett-Packard Company.In addition, some strong second-tier cities, such as Wuhan, Chengdu, and Chongqing, generally have the advantages of higher education resources, and there is no shortage of talents. It is easy for companies to recruit people, and the cost of employing personnel is much lower than that of the first-tier companies.Especially for high-end industries, their research institutes need talents, not logistics, so when most companies invest, they will first choose regional central cities such as Hangzhou, Chengdu, Wuhan, Xi'an, and Hefei.These are not available in cities in other metropolitan areas, the most typical cities are Zhongshan and Huizhou.I saw fans leaving messages at the bottom of our articles asking, "Why is there so much land in Zhongshan, cheap house prices, good location, and a good environment, but the economy is not developed?"I think I don’t need to say the answer. Zhongshan is indeed like this fan said. Compared with many cities, the conditions are already very good, but Zhongshan does not have a large talent pool. The resources of colleges and universities are average, and companies cannot recruit them in the past man.Over the years, the infrastructure of second-tier cities has been improving. Medical care, education, transportation and subway...the first line and some second lines are gradually available. For details, please refer to our previous article: Capital retreat?In addition, housing prices in second-tier cities are not expensive, and now some young people, even those without family background, are unwilling to go to first-tier cities.The migration of industry and population actually represents the direction of buying a house.Now you have some money but you can’t afford the first-tier cities. I don’t recommend you to buy in the surrounding urban agglomerations.Think about it, you live in Shenzhen and bought it in Huizhou. Now there is no subway, and the transportation is inconvenient. It takes hours to commute back and forth. The education and medical conditions are not good. If you really want to see a doctor, you have to go to Shenzhen run.In places like Zhongshan, Huizhou, the industrial facilities are not as good as those of second-tier cities. It is better for the population to stay in Zhongshan and Huizhou and return directly to the second-tier provincial capitals.If you have money to invest, you don’t have to worry about house prices not going up when you buy a house in a second-tier city.In the past, the appreciation rate of the first-tier may be faster than that of the second-tier, but it may not be the case in the future, especially the first-tier non-core general housing, I guess it will not be able to outperform the houses in the second-tier core area.For example, cities that have developed better in recent years, such as Chengdu, Wuhan, Hangzhou, Nanjing, Xiamen, Hefei, Xi'an, and other second-tier cities, the growth rate is not weaker than that of Beijing, Shanghai, Guangzhou, Shenzhen.To be honest, it is impossible for first-tier cities to regain the momentum of crazy growth in the past. You must keep in mind the words whether to live in real estate or not to speculate. The more the city has a strong trend of real estate speculation, the tighter the supervision will be.Moreover, the first-line capital threshold is high. For example, if you only have a down payment budget of 1 million, you can only buy leftovers in Shenzhen.Instead, if you go to the second line, there are many choices for this budget.There is a young couple next to me. Although they are still working in Shenzhen, they have already bought a house in Wuhan. The area is large, it is close to the subway entrance, and the surrounding schools and hospitals are all in operation. I plan to work for a few more years before going back.Finally, do a small survey. If you can't afford a first-tier house, will you choose to go back to the second-tier house? Or three or four lines? Still insist on staying in the first-tier renting a house or buying a house in the surrounding metropolitan area. This year's trend seems to have completely changed. For example, in terms of employment or income, or even what everyone thinks, there are more and more phenomena that are different from before. Maybe people who are a little older may still recall the not-too-distant mid-1990s. Some people feel completely strange and strange.The biggest anomaly is actually very simple, that is, everyone is very realistic, students are more curvy, the elderly are more self-examination, young and middle-aged people, that is, try not to consume, get married, or have W. As far as the group is concerned, the feeling has changed. In rural areas, N tubes have appeared. In cities, the prices of necessities have risen and fallen, and inflation and deflation have gone hand in hand.From a microscopic point of view, stagflation has arrived. It is not easy for everyone to find jobs, and their income has also dropped greatly. Even if there is no drop, there will be no increase.Macroscopically speaking, that is all walks of life, the primary, secondary and tertiary industries are in a downturn, whether it is production and processing, light industry manufacturing, or ordinary commerce and trade, as well as import and export, and even small service industries on the street, such as catering, hotel accommodation , life services, tourism, etc., are all on the decline!You said that Zibo BBQ in Onion Province is on fire? After all, it is an isolated case. From the perspective of breadth, the cultural tourism of the southern slaves has not yet fully responded.Flexible employment has also begun to lose its popularity. In this year's wave of unemployment, more and more people join in, with higher education and lower unit prices. , more and more volume; and self-media short video live streaming, the bonus period has passed, and now it is a process of rectifying the source and cleaning up the sand. Ordinary people have no special ability to do this, and they can't make money.The same is true for young people. Graduates are under increasing pressure on Y. Everyone understands the value of the establishment, so they all go to the public examination to go to the shore. Even 985/211 and even the sea turtles go to the landing position in the small county. However, this has begun to eliminate the non-staffed ones. Although the regular ones have been partially expanded, the constraints cannot relieve the near thirst.I even said a few days ago that the current failure rate of 16-24 has reached 19.6, this number is so weird! And some industries, such as education and training, have been wiped out in the past few years. As for the pillar D industry, after a short period of heat this year, it has fallen into a downturn.As for other consumer industries, such as automobiles, commodities, and large-scale cultural tourism, they still haven't picked up. Everyone is short of money, except for Zhou Gongzi and Catfish Princess.These are unusual appearances and signs.When more and more companies quit, even those who survived mostly began to cut wages and employees, shrinking continuously, and the number of disabled people increased. Then there are new features.This is why a large number of failures did not appear in the mask for three years, but this year has become the most difficult year to achieve Y. Even in the southeastern coastal areas, such as the free shipping area and the Yangtze River Delta, which are the frontiers with the strongest economy, and some first- and second-tier areas, many people cannot find jobs.So this year there are ten new features!1. There are more and more food delivery, courier delivery and online car-hailing on the street. There are also many older, educated people, and even many female practitioners. However, the unit price income is getting lower and lower, and the volume is getting higher and higher. The more powerful it is (as the Y rate is insufficient, forced to work flexibly).2. There are more and more pharmacies, street stalls, and small restaurants, but the homogeneity is severe, there is no special competitiveness, and the survival period is even less than three months. , can only be forced to start a business, but the risk is getting higher and higher).3. There are more and more people doing live broadcasting to sell goods, and some data say that 90% of them are not making money, while 13% of practitioners are losing money, but everyone is still flocking to it (the publicity channel allows more people to enter, but The industry is already rectifying its roots, so it is getting more and more volume).4. Many companies in the tertiary industry in the city are no longer recruiting. Many companies have begun to lay off part of their employees. In many productive enterprises and factories, the number of recruits has dropped significantly, and piece-rate wages have also begun to decline. In this way, people over the age of 36 are no longer required.5. The number of people buying F is obviously much less than in previous years, and even second-hand F is priceless (the bulk is becoming more and more cautious, and the mainstay of D production is not hot).6. Nowadays, people are becoming more and more cautious when spending money. They definitely don’t spend what is unnecessary, but they don’t paint when they don’t need to spend. If they must be spent, they should be tight-fitting. Shop around; after all, you can’t earn much. Three years of savings in masks is almost exhausted. The wife and children at home need to eat, the parents need to take medicine for the elderly, water, electricity and heating network, fried rice, oil, salt and tea, weddings and weddings, weddings and weddings.7. Prices are erratic. Some of the necessities of life are rising in price and others are falling in price. The overall consumption is deflationary, but it also manifests as stagflation. stagnation and slow L-curve continuation).8. Many leased office buildings in commercial districts are vacant. The previous tenants’ companies went bankrupt or quit their leases. There are even many shops in the vegetable market that are empty.9. Foreign M orders are falling off a cliff after the beginning of the year, and the number of employees is also reducing on a large scale (import and export are also starting to increase).10. More and more people are forced to lie down and not go to work, or they can only work as freelancers, or rely on their parents to eat and wait for death. More people control their pockets, cut down their expenses, and dare not spend as much money as before. . And more and more young people don't fall in love and don't get married, and if they get married, they don't want a baby. Even if they already want a baby, they won't want two or three just because they let go.Think about it, everyone?Now the version was changed at the end of last year and the end of the year. Now it seems that the big market is recovering, but in fact, all walks of life are basically undergoing a major reshuffle.For individuals, the age of 35 becomes more prominent. Those who are 35 years old can only graduate, and even those who go ashore are not good. They couldn’t go ashore before, and they could still hang out on the shore as a non-staff. Now they have begun to clear the non-staff. The general environment continues to be L-shaped, consumption is sluggish, and the Y is pulling. The income is unstable, and it is difficult to see through this year's market.What's next? No one knows for sure.It is precisely because the current events are so different from everyone's expectations that everyone is confused.Still those few words, here are some suggestions:Don't start a business, don't invest in Z, don't make troubles, save more money: the situation is not good, even if there is no business, life will be difficult, so you must ensure cash flow and a certain amount of savings for emergencies. And venture capital Teng, either burns savings or burns D funds, don't do it like this. Ordinary people have no resources, no connections, and no poor information. In this era of Chengdu dogs, that is to give away people's heads, so don't bother. Low-key, low-key.The body is the capital of that, and ensuring health: health is the first element of survival, and only good health is the cost of going on. Although the times are gloomy, we must ensure our health, stay up late, reduce smoking and drinking, eat a reasonable diet, exercise properly, and ensure rest. In this era, you have to survive, resist, and others fall, and you can become the ultimate victor.Don’t waste time, keep your job: Looking at 2023, it’s good to have a job. Now that you have a job, you can pay your salary on time. If you are not an ordinary person who is not short of jobs, don’t change jobs now. Survival is the first theorem, don't toss, don't be frightened, don't waver, just hang on.Give it a go, become a motorcycle by being single, and roll to death: If you are single and the whole family is not hungry, then it doesn’t matter, but many social CHUs have wives and children, and old people to support, so there is no choice but to roll , then spend more time and energy than others, and you can still gain a little bit if you are involved in death. If you earn more than others, you will have more confidence. There is no way, Chuan Jianguo said it well, life is like this, and all sentient beings suffer.Keep learning, part-time high-point sideline: If you have spare time, you can learn some skills and do a part-time job. Although it is tiring, you can earn more and improve your life. Dubbing, editing, collaboration, planning, self-media, e-commerce, You can live broadcast or anything, just earn more.Lay flat, what do you like: This is suitable for single young people. If you are sure that you will not get H or W in the future, it will be simple. Parents usually have old insurance, so you can lie flat. We don’t make cakes anymore. Don't expect points, although the quality of life may not be very good, but it is much easier.Those who are capable, China Resources Vanguard: Don’t pretend, it’s a showdown, who told us to vote for such a difficult South slave with poor TAi skills, if you are capable, learn more skills, whether it is basic such as electric welding, excavator, It is still advanced, such as biotechnology, computer, programming, etc., if you study foreign languages hard, you can get out. Although the outside area has been declining in recent years, it is still stronger than the southern slave as a whole. Northern European Luoba, Western European Luoba, Damei, Kangaroo, Maple Leaf, etc., are all fine, and they can still enjoy dividends for decades. After all, even the depression over there is still a ceiling compared to the southern slave.In April this year, Lloyd, a member of the management committee of Freudenberg Group, just completed his long-awaited trip to China. He not only visited many companies under the group and upstream and downstream industries, but also the Shanghai Technology Innovation Department just established last year. Excited.The reporter noticed that in recent years, multinational companies investing in China are no longer limited to building new factories and production lines, but also "moving" their R&D centers and business headquarters to Shanghai. Some companies' innovation parks have even been expanded three times in ten years to better cultivate local talents. human resources and serve the global market. For this reason, the agglomeration effect of Shanghai's global R&D center has been significantly enhanced, and the energy level of the headquarters economy has been continuously improved.Strengthen the layout in ChinaNot long ago, the Freudenberg Group announced its annual report for the 2022 fiscal year, and its performance in China has become one of the highlights of the annual report. According to Lloyd, the Freudenberg Group achieved sales of over 11.7 billion euros last year, a year-on-year increase of 17%, of which the sales in Greater China were 10.22 billion yuan, accounting for about 11% of the total sales."Last year was the first time for Freudenberg to participate in the CIIE. The CIIE provides an excellent platform for foreign companies to introduce advanced technologies and products to China, and also creates a window for two-way communication with Chinese partners." Ke Debao Xu Beidi, representative of Bao Group in Asia, told reporters that as a "new friend" of the CIIE, Freudenberg established contact with many potential customers during the short five-day exhibition. For example, Freudenberg Power Systems Group used the CIIE The meeting completed its first show in China, and the Chinese team of Freudenberg Power Systems has reached cooperation intentions with a number of commercial vehicle and shipbuilding companies. Due to the fruitful harvest last year, Freudenberg will continue to participate in the CIIE this year. "The CIIE is open and diverse, and Freudenberg is full of expectations for this year's CIIE." Xu Beidi said.At present, China has gradually grown into Freudenberg's third largest market, and Freudenberg, which is of German origin, also pays more attention to localization. For China's new energy vehicle market, Freudenberg's different business groups have launched products and solutions to better meet the needs of domestic consumers. "For example, our shock absorption products can improve the comfort of drivers and passengers, non-woven products can isolate noise, filters can ensure clean air, sealing and special chemical products can ensure battery operation, and gas diffusion layers in fuel cells, etc." Luo said. Ed said.Focus on localization and innovationDuring the interview, the reporter noticed that the new technological innovation department located in Shanghai was often mentioned. In May last year, Freudenberg Group's technological innovation department was established in Shanghai, which mainly conducts forward-looking research in the fields of electric transportation, new energy, sustainable development and intelligent manufacturing."This innovation department focuses on the long-term dimension, such as studying the technological trends in 2050, so as to judge which product materials or solutions may be the growth points of Freudenberg's future business." Lloyd explained that in the future Oriented open innovation requires the discovery of emerging technologies in China and the cooperation with Chinese universities, research institutions and start-up companies. Xu Beidi also said: "Shanghai has gathered the headquarters and R&D centers of many world-leading companies, and has abundant universities and scientific research resources. Shanghai's innovation and technology platform can easily attract well-educated talents. It is very important for Bao Group.”At present, the department is focusing on exploring emerging technologies in the fields of sustainable development such as raw material recycling and bio-based materials from relevant domestic universities, research institutions and start-up companies. In addition, emerging industries such as carbon dioxide capture and utilization, power battery recycling, renewable energy electrolysis of water to green hydrogen, high-temperature fuel cells, and machine vision are also the focus of attention.Since the beginning of this year, strengthening China's local research and development capabilities has become one of Freudenberg's core strategies. Many companies under the group have decided to increase investment in research and development, especially in the Yangtze River Delta region. Xu Beidi said frankly: "The Freudenberg Group's Asian regional headquarters is located in Pudong, Shanghai. Many of our investments in China are concentrated in Shanghai as the core, including the Yangtze River Delta region of Jiangsu and Zhejiang. Setting the regional headquarters in Pudong, Shanghai gives us a We bring a lot of convenience."As early as 2014, its subsidiary Klüber Lubricant started to build its Shanghai R&D center. After nearly ten years of development, the Shanghai R&D center has become Klüber's second largest R&D center in the world. Shu Mingde, Kluber's global chief technology officer, said that because China has a mature industrial chain and broad market opportunities, Kluber will continue to make efforts in traditional industries, and will also continue to make efforts in emerging industries such as smart manufacturing, new energy vehicles, and renewable energy. The field takes the lead in layout. This year also plans to increase investment in its Shanghai R&D center, and will continue to invest millions of euros in capacity expansion between 2026 and 2029 according to actual conditions.Scientific research centers become investment rookiesFreudenberg is just a microcosm of global technology multinational companies increasing investment in scientific research in China. In recent years, many chemical material industry giants have chosen to establish or expand R&D centers in Shanghai to serve the Chinese market by cultivating localized talents.Recently, Brudermüller, chairman of the executive board of BASF, said at the annual general meeting of shareholders that about half of the sales of global industries are in the Chinese market, while BASF’s sales in China account for less than 15% of the company’s total sales. Therefore, BASF is continuing to invest to continue Achieve business growth in China. He believes that the opportunities for investment and development in China far outweigh the risks, which will help make up for the slow development of the European market. To this end, BASF promises that by 2030 nearly half of its chemical manufacturing will be in China.Lou Jianfeng, chairman and president of BASF Greater China, revealed a set of data that can explain the problem better: BASF China has more than 10,000 employees, of which about 10% are engaged in innovation and R&D. Shanghai Innovation Park is the R&D center of BASF Asia Pacific. The hub is also one of BASF's global R&D centers. Since it was put into use in 2012, the expansion has been completed twice. At present, the construction of the third phase of the Shanghai Innovation Park has been basically completed and will be completed in June this year. By then, BASF's total investment in the Shanghai Innovation Park will reach approximately 280 million euros.As early as 2001, Covestro established a polymer R&D center in Shanghai and gradually developed into an innovation center in the Asia-Pacific region. Today, it has provided R&D service support to customers around the world. As the largest comprehensive production base of Covestro in the world, the Shanghai Integrated Base launched three projects last year, among which the elastomer factory is expected to be put into operation this year, and the water-based polyurethane dispersion (PUD) and its supporting production lines will also be completed next year. . Chen Yun, the general manager of the base, said that the Shanghai Integrated Base has entered its third decade and will focus on strengthening and supplementing the chain, completing the entire industrial chain and achieving zero carbon at the same time."In China for the world" has become a trendMultinational chemical companies have increased their investment in scientific research in China, which has made up for the R&D shortcomings of the domestic chemical industry to a certain extent. Statistics show that in 2020, the R&D investment of the domestic chemical industry will account for 0.9% of the total revenue, while the R&D investment of the European Union, the United States, Japan and South Korea will account for 1.9%, 1.8%, 5.6% and 3.0% of the total revenue respectively. For this reason, the "Guiding Opinions on Promoting High-quality Development of the Petrochemical and Chemical Industry during the 14th Five-Year Plan" proposes that by 2025, the R&D investment of enterprises above designated size in the petrochemical and chemical industry will account for more than 1.5% of the main business income."In the past, multinational chemical companies were accustomed to the convenience and benefits brought by globalization, and slowed down the pace of basic research and development with high investment and high risk. However, under the background of energy transformation, multinational chemical companies will restart R&D and innovation." China Chemical Industry Information According to the analysis of the center, scientific and technological innovation is and will continue to become the core competitiveness of global chemical companies. In the next three years, the development opportunities of China's chemical industry will focus on technological change, double carbon and stable economic growth.A research report by the Shanghai Development and Reform Research Institute also pointed out that the status of foreign-invested R&D institutions in Shanghai in their parent companies and in the world is constantly improving, and they are gradually developing R&D activities that are of great strategic significance for long-term development in China and the world . At present, a large number of foreign-funded R&D institutions in Shanghai have the ability to develop new products for Asia and the world, and the innovation model of "in China for the world" has become an important development trend of foreign-funded R&D institutions in China.In recent years, Shanghai has continuously increased its efforts to attract foreign investment, and the agglomeration effect of R&D centers has been significantly enhanced. In December 2020 and November 2022, Shanghai successively issued revised policies on foreign-funded R&D centers and regional headquarters of multinational corporations, adding "global R&D centers" and "division headquarters of multinational corporations" to continuously improve the economic level of headquarters. Last year, Shanghai added 60 regional headquarters of multinational companies and 25 foreign-funded R&D centers. Over the past 20 years, a total of 891 regional headquarters of multinational companies and 531 foreign-funded R&D centers have been established, continuing to play the role of resource gathering and radiation of the headquarters.最近各个省份的人口数据都差不多出来了,又有新变化。人口走势有一个很明显的变化是,之前那些人口增量一线都市圈,纷纷出现了调减的情况。 先是京津冀都市圈,继2021年负增长29.84万人后,2022年人口流失规模扩大至42.3万人。其中,北京市人口减少了4.3万人,天津市人口减少了10万人,河北省的人口减少了28万人。如果按照这个速度减下去,10年整个京津冀地区将会净流出人口高达300-400万人,甚至会更多。还有长三角都市圈。去年整个长三角的人口增量只有47万人,10年来首次跌破100万,创下了历史最低。江苏省的净增人口数量也从28万人减少到10万人,减少了一半。浙江从净增人口72万人减少到37万人,也是减半。上海市更是出现了直接负增长的情况,常住人口从2489万人减少到2475万人,是10年内人口减少最多的一次。长三角作为经济高度活跃的地区,一直都有人口吸引力。但即便是像上海这样的大城市,这几年人口流失的趋势也开始显现出来了。那人口流动走向都有哪些趋势呢?一是都市圈的内部迁移。比如长三角都市圈,从上海流出的人口,来到了安徽。安徽的净增人口在逐年增加,去年已经净增14万。二是从一线到二线城市圈的迁移。去年重庆的人口增量净增了7.7万,江西省净流入人口9.4万人,内蒙古自治区净流入人口6.5万人。成都的情况也类似,人口从2021年的82.8万人略微增加至84.2万人。用脚投票的数据往往才是最有力的。大都市圈的吸引力,已经不如之前那么强劲。随着人口流动大洗牌,二线省会城市已经崛起了。为什么很多人都想往二线城市跑了?我认为有两点原因。1、一线城市的生活成本太高了。先不说买房,光是养娃这一项,就能把人给榨干。如果你要鸡娃,搞各种培训,一年几十万都有可能。之前有育娃研究员做过统计,要把一个孩子培养到成年,一线城市随随便便就是百万起步。试问有多少普通家庭可以付得起这个成本?2、产业迁移驱动。除了华为这种少数转移到东莞的,还有周边城市群除了低端制造业就近转移外,高端产业都不会选择周边都市圈。因为这些周边城市群,除了物流近之外没有其他优势,也没有形成产业链。像河北和天津一样,北京的产业是转移过来了,但他们承接不住啊。反观现在的二线城市,对落地的企业非常友好,无论是政策还是营商环境,像极了早期的一线城市。首先,很多二线在招商引资上,特别是高端产业上是很舍得投入的,周边都市圈没有这个优势去跟二线去抢。你看像京东方去合肥投资几百亿,当时合肥政府拿出了家底投资京东方股份,另外土地、税收都有巨大优惠。还有一些强二线城市,率先发展起新兴产业,直接和大城市抢产业。比如杭州高新区早年通过产业链招商,引进了一批像吉利集团、海亮集团的顶尖高新企业,致力于人工智能、云计算、大数据、物联网等顶尖核心技术的研发。还率先打造了大健康产业集群,如今全球前十大药企中,已有一半在杭州经济技术开发区投资。二线城市没有产业链怎么办?那就制造一条出来,把整个产业链给垂直整合了。像威海高新区,为了惠普产业链量身定制了占地6000亩的激光打印机产业园,同时针对产业链发展所需定制配套了生产、研发、检测、认证等服务,最终引进了美国惠普公司。另外,一些强二线,比如武汉、成都、重庆普遍都有高校教育资源优势,不缺人才,企业想招人很容易,用人成本也比一线低很多。特别是高端产业,他们的研究院需要的是人才,不需要物流,所以大部分企业去投资的时候,都会首选杭州成都武汉西安合肥这样的区域中心城市。这些是其他都市圈的城市所不具备的,最典型的就是中山、惠州这些城市。之前就看到粉丝在我们文章底下留言问“为什么中山地多,房价便宜,位置不错,环境又好,经济却不发达呢?”我想这个答案已经不用我说了,中山确实如这个粉丝说的这样,相比于很多城市,条件已经很好了,但是中山没有大量的人才储备啊,高校资源一般,企业过去了招不到人啊。这些年来,二线城市的基础配套一直都在完善。医疗、教育、交通地铁......一线有的二线也慢慢都有了。详细可以看我们之前这篇文章:资本大撤退?再加上二线城市房价还不贵,现在有些年轻人,没有家庭背景的也不愿意去一线卷了。产业、人口的迁移,其实也代表着买房的方向。现在手里有点钱但是买不起一线城市的,我不建议你往周边城市群买。你想想你住在深圳,买在惠州,现在没有地铁,交通也不方便,光是通勤时间来回就要花上好几个小时,教育医疗条件也都不好,真要看病,还得往深圳跑。像惠州中山这种地方,产业配套都不如二线城市,人口留在中山惠州还不如直接回流二线省会城市。那手里有钱要投资的,买二线城市的房子,你也不用担心房价不涨。过去也许一线升值速度跑得比二线快,但未来不见得,尤其是一线非核心的普宅,我估计会跑不赢二线核心区的房子。比如这几年发展得好一些的城市,成都、武汉、杭州、南京、厦门、合肥、西安等二线城市的涨幅,其实不比北上广深弱。说实在的,要想让一线城市重现以前疯狂涨幅的势头,那是不可能的。房住不炒这几个字要牢牢记住,越是炒房风气重的城市,上头盯得越紧。而且一线的资金门槛高啊,比如说你只有一百万的首付预算,在深圳你只能买到边角料。反而去二线,这个预算的选择就很多了。我身边就有一对小夫妻,人虽然还在深圳上班,但已经在武汉买了房子。面积大、离地铁口近、周边学校医院全齐活了,打算再打几年工就回去了。最后做个小调查,如果你买不起一线的房子,会选择回二线吗?还是三四线?还是坚持留在一线租房或者去周边都市圈买房。
