Urban Size Is Determined by Natural Endowment:China's Experiences and It's Enlightenment
In the process of the rapid urbanization and continuous adjustment of the urban system in China,it is of great theoretical and practical significance to clarify the determinants of the urban size.This paper proposes the idea that the urban size is determined by the natural endowment,and uses China's urban data during 1985-2020 to test it.It is found that the dummy variable of the eastern coast city is significantly positively correlated with the urban size and the urban growth,which is strengthened by the reforming and opening up.The climate amenity measured by the average minimum temperature in January is significantly correlated with the urban growth,and people tend to migrate to places with warm winter.There is a significant negative correlation between the relief degree of land surface and the urban size.The dummy variable of the resource-based city is significantly negatively correlated with the urban size and the urban growth.A higher administrative level or the supporting policy can strengthen the advantages of the natural endowment,but it is difficult to reverse the disadvantages of the natural endowment.Based on the research,we should respect the law of development,adapt measures to promote urban development in various regions in line with local conditions,optimize the functions of cities at deferent levels,and actively strengthen regional cooperation,promote common prosperity in all regions.
