Exploring the Association between Urban Form and Air Quality in China

This article aims to evaluate the association between urban form and air quality in China through the use of empirical evidence. The relationship between a variety of urban form metrics and concentrations of air pollutants were analyzed through linear regressions using a data set of cross-sectional observations from 157 Chinese cities. After controlling for other explanatory variables, higher population density and lower urban continuity are commonly associated with better air quality, and urban form could play a modest but important role in improving air quality for Chinese cities
