TAN Xian-dong,HU Zhao-guang,SHAN Bao-guo (State Grid Energy Research Institute,Beijing 100052,China)  
An uncompetitive input-output table with 43 sectors is compiled according to three basic input-output tables published in China.An uncompetitive input-output model for analyzing embodied electricity in exports of China is established.The amounts of embodied electricity in China′s exports of year 1997,2002,and years from 2007 to 2010 are calculated based on the proposed model.The sensitivity analysis of impacts of exports change rate and structure change on embodied electricity is performed.The results show that the embodied electricity in exports of China grew rapidly after entry into WTO.It reached about 1 010.2 TWh in year 2007.For years from 2008 to 2010,the growth of embodied electricity slowed down apparently because of global economic crisis.The amount of embodied electricity was around 1 058.2 TWh in 2010.A decline of one percent on exports leads to 0.8 percent of embodied electricity decrease and a decrease of 0.18 to 0.28 percent of total electricity consumption growth.
