【摘要】：传统DEA方法研究碳减排潜力时以能源效率最优行业为参照标准,忽视了行业低碳发展存在阶段性特征的事实,测算的减排潜力值在短期内难以全部释放,不能作为我国工业部门制定碳减排目标的依据。而改进的广义DEA模型可自由选择参照集进行评价,因此,本文尝试采用比各行业低碳发展阶段高一级的行业组为低碳发展标准,并对比分析两种方式下的碳减排潜力。结果显示:(1)我国工业部门2011年低碳发展水平总体可以分为5个阶段,处于低碳发展一般阶段的行业比例最大,为36.8%;(2)阶段式减排下绝大多数行业比传统方式下要求的减排量减少,工业总体要求减排量降低8.1%;(3)我国工业部门推进碳减排工作的重点行业为非金属矿物制品业,化学原料及化学制品制造业,煤炭开采和洗选业,重点部门为采矿业。
[Abstract]:The traditional DEA method studies the potential of carbon emission reduction by taking the energy efficiency optimal industry as the reference standard, neglecting the fact that the industry has stage characteristics of low-carbon development, and the calculated emission reduction potential value is difficult to release completely in the short term. The improved generalized DEA model can freely select reference set for evaluation. Therefore, this paper tries to adopt the industry group which is higher than the low carbon development stage of each industry as the low carbon development standard. The results show that in 2011, the low carbon development level of China's industrial sector can be divided into five stages, and the proportion of industries in the general stage of low-carbon development is the largest. Under the stage of emission reduction, most industries will reduce the emission reduction required under the traditional mode, and the overall industry will require a reduction of 8.1%.) the key industries in China's industrial sector to promote the reduction of carbon emissions are the non-metallic mineral products industry. Chemical raw materials and chemical products manufacturing, coal mining and washing industry, key sectors for mining.
