Abstract:In recent years, the PM2.5 index rise has seriously affected the health and quality of people’s life and becomes the focus of the people. Based on world input-output tables developed by OECD and WTO, this paper compares the production of the every walk of life and ultimate product export between Chinese and EU member states’ PM2.5 source gas emissions coming from product, trade and emissions intensity and conducts SDA decomposition for the change of export emission amount. Analysis shows that during 1995- 2009, PM2.5 source gas emission increases 88% and 97% from Chinese production and ultimate product export while EU member countries except Denmark decrease, and that the PM2.5 sources gases emission intensity of China is highly bigger than that of EU member countries. The main cause for the rise is export’s rise of China, input-output structure change also causes the emission increase, and however, the emission intensity decrease effectively reduces the emission amount. Although EU main member countries’ export has different increase, their emission amount has negative growth because of their input-output structure optimization and lower emission intensity. China should further decrease emission intensity of the pollutants, optimize industrial structure and export product structure in order to effectively reduce PM2.5 sources gases emission amount.
