Why are most of the 10 cities with the largest net inflow of population in the south at present?

With the rapid development of China's social economy, the advancement of urbanization and the reform of the household registration system, the population flow between various regions has become increasingly active, and the scale of floating population has expanded rapidly. Most of the 10 cities with the largest net inflow of population are in the south. This has led people to wonder why most of them are southern cities

And the population of the once glamorous northern cities continues to flow out. There are several reasons for this.

First of all, the south has been relatively economically developed in recent years, and people like to go to economically developed areas. The floating population tends to be counties and cities with higher wage levels, larger non-agricultural employment scales, and higher administrative management levels, the floating population is more inclined to counties and cities with higher administrative levels and salary levels, because the counties and cities in the northern region have a lower level of economic and social development, and the differences between counties and cities are large. Cities are important, and most of the cities in counties with higher wage levels are provincial capitals or prefecture-level cities with higher administrative levels, so the floating population in the northern regions is concentrated in the south.

The floating population in the western region is similar to that in the northern region, and is more inclined to counties and cities with higher non-agricultural employment scale and total urban wages, while the floating population in the northeast is more inclined to the southern provincial capitals with a larger scale of non-agricultural employment.

Secondly, climatic reasons. The climate in the south is warmer in winter. In most areas north of the Qinhuai River, rivers and lakes freeze over winter.

In winter, the north wind blows through and most of the trees lose their leaves. The leaves that do not fall are mostly coniferous and are called conifers. Due to the low annual precipitation in northern China, most of the precipitation is concentrated in summer, so the river volume is not large, and the water level varies greatly.

The flood season can only be formed in summer, which is relatively short, and the sediment concentration in the rivers is large. South of the Qinhuai River, however, the opposite is true. In winter, there is no ice, no fallen leaves and evergreen all year round.

The river has a large amount of water, the water level does not change much, the flood season is long, and the sediment content of the river bottom is small. The climate is suitable for human life.

Because the south is relatively economically developed, and the climate in the south is not as cold as in the north.

Behind the collective negative population growth of the four first-tier cities in Beijing, Shanghai, Guangzhou and Shenzhen, there are the following reasons:

1.Outflow: Due to the high pressure of urban burial and the high cost of living, some young people choose to leave the city in search of better job and life opportunities in other areas. At the same time, some elderly people choose to move out or return to their hometowns to retire, which will also lead to population loss.

2.Population restriction policies: Many first-tier cities** have introduced population restriction policies, such as raising the household registration threshold and canceling social security and provident funds for permanent residents, which may also lead to a certain amount of population loss.

3.Impact of the epidemic: After the outbreak of the epidemic, many businesses closed or reduced hiring, and some out-of-town personnel also chose to leave the city and move to other areas.

The emergence of this phenomenon has released some signals:

1.Urban development needs to be promoted and optimized: Urban development needs to focus more on humane and sustainable development models, and retain urban populations by improving the quality of life of citizens, strengthening social and public services, and creating better employment opportunities.

2.It is necessary to better solve the living problems of urban residents: the problems of high living costs and relatively simple cultural and entertainment atmosphere of urban residents need to be better solved.

Rental housing problems, education costs, health care and other aspects of the cost reduction policy need to be continuously introduced to improve the quality of daily life of urban residents.

3.Urban planning and management need to be strengthened: Urban planning needs to place more emphasis on the construction of urban space and human environment to avoid excessive concentration of urban population.

In short, the phenomenon of collective negative population growth in the four first-tier cities of Beijing, Shanghai, Guangzhou and Shenzhen provides us with many signals to think about the need to better balance the relationship between population and urban development, and promote the sustainable development of cities.

In 2019, Shanghai, Beijing, Shenzhen-Dongguan-Huizhou, Guangzhou-Foshan-Zhaozhou metropolitan areas ranked first in terms of development potential, followed by Suzhou, Xichang, Tianjin, Nanjing, Chengdu, Hangzhou, Chongqing, Wuhan, Changsha-Zhuzhou-Zhuzhou-Tan and other metropolitan areas. Shenzhen, Dongguan, Huizhou, Guangzhou, Foshan, and Zhaozhou have led the country in population growth in recent years, with an average annual increase of 10,000 permanent residents from 2015 to 2018, and metropolitan areas such as Hangzhou, Chongqing, Changzhutan, Shanghai, Zhengzhou, Xi'an, Wuhan, and Chengdu have also increased significantly, mainly contributed by central cities except for the Shanghai metropolitan area. The Yangtze River Delta, the Pearl River Delta region and the Beijing metropolitan area have the highest economic scale and leading industrial innovation strength.

The Shanghai metropolitan area is unbeatable with a trillion yuan of GDP; Shanghai, Beijing, and Shenzhen-Dongguan-Huizhou metropolitan areas occupy an absolute advantage in industrial innovation, and the total number of A+H share listed companies and the number of invention patents authorized account for % of the country.
