摘要
基于投入导向的超效率DEA模型,测算2000—2011年我国36个工业行业碳排放效率,通过绝对收敛和核密度分析其动态演进特征。结果表明,我国工业平均碳排放效率值为0.677,整体效率较低,其中轻工业效率值最高,其次为重工业、采矿业和供应业;绝对收敛显示,2000—2011年全行业、采矿业和重工业通过了收敛检验,存在对碳排放效率高的行业的追赶效应;核密度分析可知,全行业及四大类别碳排放效率都得到了不同程度的提升,但内部行业间变动趋势存在明显不同。
With the super- DEA model which is based on the input oriented,this paper estimates the emission efficiency in Chinese 36 industrial sectors during 2000- 2011,and then analyzes the dynamic depiction through absolute convergence and kernel density estimation. The results show that： the industrial average emission efficiency is 0. 677,which is relatively lower; In the measure of the emission efficiency,the efficiency of light industry is the highest,followed by heavy,mining and supply; Absolute convergence shows that the whole industry,mining and heavy industry pass the convergence test,having catch- up effect to industrial sectors of the high emission efficiency; through kernel density estimation,the emission efficiency of the whole industry and the four categories have made various improvement,but no obvious changes between internal industries.
