Grid management and air quality of Xi’an city
Abstract
Xi’an was the first city which came up with grid management. Since the implementation of grid management, the air quality of Xi’an has improved quite obviously. But, factors influencing air quality are so many. Thus, we should further launch an empirical research to obtain the grid management impact on air quality. This paper explores it in the way setting policy dummy variable, and the research result manifests that grid management improves the air quality obviously, especially, in the aspect of NO2, SO2. In a nutshell, grid management can provide “Xi’an Model” in the perspective of Haze Management.
