Whether suburbanization exacerbates or alleviates urban diseases: evidences from Shanghai, ChinaSep. 3,2019
Suburbanization is an inevitable trend in the development of metropolises. Taking Shanghai as an example, the combination of qualitative and quantitative analysis was adopted to analyze the impact of manufacturing suburbanization and residential suburbanization on urban development in Shanghai. The results are as follows. (1) Manufacturing suburbanization has generally improved the air quality of urban environment, but the impact on the downtown and suburb is opposite. (2) Residential suburbanization has aggravated the separation of occupations and residences in the downtown and suburbs and has worsened the traffic congestion around the downtown. (3) Manufacturing suburbanization and residential suburbanization have both resulted in excessive consumption of land resources to some extent. Therefore, with the deepening of suburbanization in Shanghai, it is necessary to control and reduce the emission concentration of NO2 and PM2.5, and to promote the integration of production and city. It is necessary to focus on the conservation and intensive use of suburban land and control of housing prices. We will pay more attention to the adjustment and optimization of population structure, industrial structure, land use structure and spatial structure in the outskirts, and strive to build Shanghai into a global city which is resource-saving, environment-friendly, socially harmonious and ecologically livable.
