Study on Trend of Air Quality and its Affecting Factors in Wuhan
This document analyses change of air quality of Wuhan basing on Urban Air Quality Daily Report (UAQDP) data during 2001-2010. The paper includes four parts: The first part focuses on changing trend of three air quality indicators (concentration of SO2, PM10, NOX). The second part analyses potential factors which affect air quality through grey correlation analysis method. I find that atmospheric temperature and economic growth are the most important factors among them. In the third part, I try to test if the relation of Wuhan’s air quality and economic growth verify Environmental Kuznets Curves (EKCs) hypothesis. The results show that SO2 increase first and decrease after GDP per capita increasing to 18000 Yuan, which form inverted U shape, while PM10 decrease and NOX increase continuously along with GDP growth. EKCs hypothesis is supported partly in Wuhan. The fourth part is a conclusion.
