The Study of SO_2 Emissions Embodied in International Trade of China

摘要

Using input-output model, this paper calculates the emission coefficients of SO_2 of China's industry and emission of SO_2 embodied in international trade between 2005 and 2010. Furthermore, the paper analyzes the effects of technical factor, trade scale and trade structure. The emission of SO_2 embodied in export exceeds the SO2 embodied in import, and both SO_2 emission of export and import declined during 2005-2010. The effect of technical on the emission is greater than that of trade scale; and the effect of trade structure is smaller.
