The Influence Of Foreign Trade On China’s CO₂Emission And The Driving Factors

With the increase of focus on the carbon emission in the international society andmore importance of international trade in the Chinese economic development. This paper studiesthe influence of foreign trade on the CO₂emission by using MRI-O model and accounts for theinfluences by using Structure Decomposition Analysis and Divisia Index decomposition. Theresults show that foreign trade can reduce CO₂emission intensity （PTT） but will increase theCO₂emission （BEET）.The results of Structure Decomposition Analysis on the CO₂embodied inthe export indicates five factors can account for the increase of CO₂.Divisia IndexDecomposition into BEET from each sector show scale effect （trade surplus） is the main cause ofthe CO₂emission increase while technology effect can decrease it, and composition effect isuncertain. Also, this paper explores the driving factors of PTT by Divisia Index Decompositionto exclude the scale effect on CO₂emission. The result shows technology effect can reduce thePTT while composition scale is still uncertain, and adjusting the "cross" influence between themis effective to reduce the PTT.
