Decomposition Model and Empirical Study of Carbon Emissions for Jiangsu Province

Nowadays,carbon emissions mainly caused by energy consumption in China.These years with the population growing and economy expanding,the sharply rising consumption of energy and the severe coal-focused energy structure are very difficult to change in short-term,causes the carbon emissions of Jiangsu Province increase continued.A decomposition model of carbon emissions per capita for Jiangsu Province is set up by adopting Logarithmic Mean Weight Divisia(LMD) method based on the identity of carbon emissions.The model is adopted to analyze the influence of economic development,energy structure and energy efficiency to carbon emissions per capita in Jiangsu from 1996 to 2007.The results show that the contribution rate of economic development to carbon emissions per capita is exponential growth,however,the contribution rate of energy structure and energy efficiency restraining to carbon emissions per capita is still unapparent,which cannot offset the driving force of economic development to carbon emissions.The speed of carbon emission increasing has been decreased since 2005,which demonstrates that although the target of emission abatement has not been coming true,the efforts on energy conservation and pollution reduction in Jiangsu have achieved initial results.
