Abstract: By using the technical heterogeneity assumption and non-competitive input-output tables extracted from WIOD database, this article estimates the embodied carbon in China-Japan trade during 1995—2009,which is generated from energy consumption and industrial production process, with a multi-region input-output model. Furthermore,by employing the structure decomposition analysis(SDA)approach, this article analyzes the driving forces of embodied carbon in exports from China to Japan during 1995—2009. The result shows that, in trade with Japan, the embodied carbon in China's exports increased from 40.78Mt to 152.78Mt, the embodied carbon in China's imports increased from 12.25Mt to 66.87Mt, and the net embodied carbon exports increased from 28.53Mt to 85.91Mt. With SDA analysis, this article also finds that the scale effect had a large influence on the increase of carbon embodied in China's exports, and the technical effect is the primary cause in the decreasing of embodied carbon, while the influence of the structure effect is relatively small.
