Abstract: A few major cities in China recently have implemented driving restriction policy (DRP), mainly due to the air pollution and traffic jam issues. This paper investigates the effect of the driving restriction policy on the reduction in air pollution. Different from the commonly used approaches in previous studies, such as regression discontinuity regression and difference-in-differences, we construct the counterfactuals for the air pollution index (API) for these cities which have implemented DRP using the method proposed by Hsiao, Ching and Wan(2012). Other cities of the 35 major cities without the DRP are treated as the possible control cities. We analyze both the weekly API and the daily API to evaluate the effect of DRP, and the results show: that the DRP has a significant effect on decreasing the APIs of Beijing, Guiyang and Chengdu, while the effects on reducing the APIs in Nanchang, Changchun and Hangzhou are not statistically significant.
