The Impact Of Infrastructure And Its Equalization On Urban Sprawl

At present,high-quality urbanization plays an important role in China's economic development.With the continuous promotion of urbanization,the demand for urban land area is increasing,and the growth rate of urban land area has far exceeded the growth rate of urban population,which makes the urban sprawl disorderly.At the same time,the problem of urban sprawl is more obvious.As an important material support for urban spatial development,infrastructure has an important impact on urban sprawl.How to improve the level of infrastructure and realize its equalization is of great significance to curb urban sprawl and promote the coordinated development of urbanization space.This paper analyzes the influence mechanism of infrastructure and its equalization on urban sprawl,and takes 27 cities in Yangtze River Delta as the research object,constructs a comprehensive index system of infrastructure and its equalization,and measures it with the methods of comprehensive index and deviation degree respectively,tests the influence degree of infrastructure and its equalization on Urban sprawl,and further governs urban sprawl It provides a reference for the coordinated development of urban space.The results show that:(1)infrastructure and its equalization have a positive impact on urban sprawl.But the impact of infrastructure is greater than that of equalization.(2)When the equalization of infrastructure is realized,the impact of the improvement of infrastructure level on urban sprawl is reduced.Blindly increasing the infrastructure stock makes the urban land disorderly and inefficient expansion,which intensifies the urban sprawl,and the realization of infrastructure equalization has a certain inhibitory effect on the urban sprawl.The government should abandon the development mode that only pursues the increase of stock,pay more attention to the realization of the universality of infrastructure among urban residents,weaken the influence of urban sprawl,and improve the high-quality development of urban space.
