Carbon emissions reduction in the industrial sector is a key way for regional low-carbon transformation.Based on the input-output table of Hunan Province from 2007 to 2017,this study conducts a structural decomposition analysis of the carbon emission increment of Hunan's industrial sectors from the demand-side perspective.The results show that from 2007 to 2017,the carbon emissions of Hunan's industrial sectors increased from 195 million tons to 286 million tons,but the five-year average annual growth rate decreased from 6.33％to 1.52％.The carbon emissions growth of Hunan's industrial sectors is mainly affected by the investment expansion effect,followed by the consumption pulling effect and the outflow change effect.The impact of the resident consumption pulling effect increased rapidly after 2012.The main factors restraining carbon emissions are inflow substitution effect and energy intensity effect.At present,the energy structure effect still weakly promotes carbon growth,and the production structure effect has shifted from carbon reduction to carbon growth since 2012.From 2012 to 2017,the changes in carbon emissions of 10 out of 28 industrial sectors in Hunan exceeded 5 million tons,which are mainly affected by the"troika"of economic growth(investment,consumption and exports),while the effect of related factors of technological progress is relatively weak.The results provide certain theoretical references for the formulation of low-carbon transformation policies in Hunan Province.
