Abstract: It is of great significance for adjusting the industrial structure to measure industry carbon emissions systematically and select the main influencing factors. This paper update Input-output table in 2010 using RAS, and adopt Polar decomposition average method to structural decompose four parts of industry carbon emissions in 2007-2010. The results show that industrial structure adjustment should be the effective way of reducing direct carbon emissions; indirect emissions account for about 80% of China's carbon emissions, impacted by carbon intensity changes largely; import and export structure adjustment will become important breakthrough to reduce import and export of products of carbon emissions. The research could provide methodological reference for the study of industry carbon emissions influencing factors, and the results have value for China's low carbon economy development.
