Estimating the Impact of Urbanization on Air Quality in China Using Spatial Regression Models (23 page pdf, Chuanglin Fang, Haimeng Liu, Guangdong Li , Dongqi Sun and Zhuang Miao, Sustainability, Nov. 20, 2015)
Today we review research into the main characteristics of close to 300 Chinese cities that affect the degree of urban air pollution. Results indicate a close relationship between population density and private cars per unit of developed urban land and that this and the proportion of secondary industry has the greatest effect on the pollution of most cities, especially in the North (in Beijing, Tianjin, Hebei, Henan, and Shandong). The authors recommend that China strictly control the scale of their mega cities and actively develop small and medium sized cities to offset these trends.
