以资本、劳动和能源作为投入变量,以各省份GDP为期望产出变量,以二氧化碳排放量为非期望产出变量,在全要素生产理论框架下,基于DEA方法定义能源利用的经济效率和能源利用的环境绩效两类能源效率指数;运用非径向、非角度的SBM模型测算2000年至2010年中国各省份的能源经济效率和能源环境绩效及其分解指数,分析其演变规律与地区差异性;基于环境库兹涅茨曲线理论实证分析中国能源经济效率和能源环境绩效及其分解指数与区域经济增长之间的关系。研究结果表明,样本期内,中国能源经济效率和能源环境绩效整体水平均较低,地区差异明显,节能减排潜力巨大;能源经济效率和能源环境绩效及其分解指数与经济增长之间存在倒U形或U形曲线关系;产业结构、人口密度、能源结构和外资利用对能源经济效率和能源环境绩效均有显著影响,但是影响机制存在差异。

Taking capital, labor and energy consumption as input variables, the GDP of each province as expected output varia- bles, carbon dioxide emissions as unexpected output, this study defines two kinds of energy efficiency indexes, namely the energy economic efficiency （EEE） and the energy environmental performance （ EEP）, based on total factor production theory and DEA method. The research employ the non-radical and non-angled SBM model to calculate China＇s provincial EEE and EEP as well as decomposition indexes from 2000 to 2010, and then analyzes their evolution rules and regional differences. We empirically ana- lyze the relationships among the EEE, the EEP, decomposition indexes and the regional economic growth by environmental Kuznets Curve （EKC） theory. The results show that the EEE, the EEP and the decomposition index are in a low level in the sample period. The regional difference is significant and there is large potential of energy conservation and emissions reduction. There are inverted U-shaped and U-shaped curvilinear relationships between the EEE, the EEP, their decomposition indexes and China＇s regional economic growth. The industrial structure, the population density, the energy structure and the utilization of foreig investment exert remarkable impacts on the EEE and the EEP through differentiated influencing mechanism.
