摘要
采用改进的指数分解法LMDI对我国1994—2003年工业高耗能行业与中低耗能行业CO2排放影响因素的差异性进行比较研究,结论表明:工业经济增长效应和子行业结构效应对两类行业CO2排放分别起到加剧和减缓的作用;高耗能能源强度效应经历了从加剧CO2排放到抑制CO2排放的转变,而中低耗能行业相应值在整个样本期都起到减排的作用;子行业能源消耗结构效应对高耗能行业起较小的减排作用,对中低耗能行业起加剧的作用且有不断扩大的趋势;CO2排放系数效应对两者影响都较小。
The influencing elements of different consuming energy industries of CO2 emission are dif- ferent, we compare, by implying the improved index decomposition method LMDI, the differences of influencing factors of CO2 emission between energy - intensive and non energy-intensive industries from 1994 to 2003. Our findings are as follows. Firstly, the economic and structural effects separately increase and alleviate CO2 emission. Secondly, the energy intensity effect experiences a transition from increasing CO2 emission to restraining CO2 emission, while it shows the CO2 emission declining trend from non energy-intensive industries during the whole sampling times. Thirdly, the alleviating function of structural effect on CO2 emission is relatively low in non energy-intensive industries but is quite high and maintains a trend of consistent enlargement in non energy-intensive industries. Fourthly, the impact of coefficient effect of CO2 emission is not obvious on both energy intensive and non energy intensive industries.
