摘　　要：首次将中间投入强度及投入结构引入到碳排放强度影响因素研究中,选用2000年、2002年、2005年、2007年及2010年的数据,运用LMDI因素分解方法将我国碳排放强度的影响因素分解为能源结构效应、能源投入替代率效应、投入结构效应和中间投入强度效应。结果表明,能源投入替代率加快碳排放强度的降低,中间投入强度和投入结构抑制碳排放强度的降低,能源结构对碳排放强度的降低作用不明显。从因素总效应来看,除了2002—2005年间各影响因素整体抑制了碳强度的降低外,其他各区段间因素效应之和加速碳强度的降低。因此,调整投入结构、提高能源效率成为碳减排的当务之急。The intermediate inputs intensity and input structure were first introduced into the carbon intensity factors study.Data from 2000,2002,2005,2007,2010,were selected as samples; impacts from energy structure energy input rate of substitution,put- into structure and intermediate inputs intensity structure were examined in detailed with LMDI method.The results showed that energy inputs replacement rate played an important part in decreasing China＇s carbon emission intensity,and intermediating inputs intensity structure; put- into structure had a negative contribution to the reduce of carbon intensity,while energy structure did little effect on carbon intensity. According to the analysis results,the total effect suppressed the reduce of carbon intensity from 2002 to 2005,while accelerated it in other sections. Therefore,adjusting the investment structure and improving energy efficiency were the urgent priority.
