超效率DEA 碳排放绩效 差异
超效率DEA 碳排放績效 差異
초효솔DEA 탄배방적효 차이
super-efficiency DEA ; carbon emissions performance ; difference
建立考虑资源禀赋限制的全要素指标体系,运用超效率DEA模型,对中国28个省(市、自治区)“十一五”期间碳排放绩效予以评价,在此基础上梳理各区域碳排放绩效演化特征.进而把握各区域内部及区域之间差异变化规律。研究发现:“十一五”期间,中国整体碳排放绩效保持较高水平,但提升速度相对较缓慢;三大地区中,东部地区绩效最高,西部地区提升速度最快;全国各省(市、自治区)间在2006-2009年差异较稳定,之后呈发散态势,东部地区与全国情况基本一致,中部地区发生a收敛,西部地区差异变动较大.三大地区间的差异变动较小.
建立攷慮資源稟賦限製的全要素指標體繫,運用超效率DEA模型,對中國28箇省(市、自治區)“十一五”期間碳排放績效予以評價,在此基礎上梳理各區域碳排放績效縯化特徵.進而把握各區域內部及區域之間差異變化規律。研究髮現:“十一五”期間,中國整體碳排放績效保持較高水平,但提升速度相對較緩慢;三大地區中,東部地區績效最高,西部地區提升速度最快;全國各省(市、自治區)間在2006-2009年差異較穩定,之後呈髮散態勢,東部地區與全國情況基本一緻,中部地區髮生a收斂,西部地區差異變動較大.三大地區間的差異變動較小.

Total factor index system which puts resource endowments limit into consider is established and super-efficiency DEA model is used to evaluate the carbon emission performance of China's 28 provinces and cities during the " Eleventh Five-Year" amt on this basis to combe the evolution characteristics of the regional carbon emissions performance, and then grasp the differences variation within the region and between regions. Studies found that during tile " Eleventh Five-Year", China's overall carbon emissions performance maintained a high level, but the lifting speed was relatively slow ; the eastern region had the highest performance of the three regions, and the western region enhanced the fastest; difference among provinces and cities was stable in 2006-2009, and then showed a divergent trend, the eastern region was consistent with the national situation, while the central region showed a convergence and the western region changed a lot, changes of the differences in the three regions was small.
