Abstract: Carbon intensity in exports(CIE)was proposed to co-investigate the value added and carbon emissions in exports, and explore the influence of global value chain(GVC)participation on China's carbon intensity in exports. China's GVC participation and CIE evolution features are analyzed during 2002-2014. Econometric models were constructed to explore the influence of different GVC participation indexes on China's overall and industrial CIE, as well as the adjusting effects of economic scale, trade structure and technological progress. The results show that:China's overall industries mainly participate in GVC in a backward way, manufacture industry has a deeper GVC participation degree, while service industry has a higher position. China's overall CIE shows a rising and falling trend before and after 2005. CIE levels of different input intensive manufacture and service industries were significantly different. In addition to position index, GVC forward and backward participation degree, and forward production length and depth GVC index have positive effects on China's overall CIE, and the improvement of depth GVC index has the most significant effect on CIE. Compared with manufacture industry, the improvement of backward participation degree and forward production length of service industry weakens the promoting effect on CIE. Compared with labor-intensive industries, the improvement of position index of capital intensive industries will further reduce CIE, and the improvement of depth GVC of capital and knowledge intensive industries weakens the pulling effect on CIE. The adjusting effect of economic scale is not significant, trade structure and technological progress will reduce the positive impact of forward participation and depth GVC on CIE. Finally, policy implications are suggested to reduce CIE in China based on the conclusion of the research.
