【摘要】 运用2000-2007年中国省际面板数据,以二氧化碳、二氧化硫排放量作为能源利用形成的环境效应替代变量纳入全要素能效研究体系,选取基于投入导向的规模报酬不变CCR-DEA模型,测算了包含环境效应的中国省际全要素能源效率,并在此基础上计算得到中国各地区2000-2007年的节能减排潜力,采用Tobit模型检验了中国节能减排潜力的影响因素。实证分析结果表明:当前中国全要素能效整体水平偏低,各地区、三大区域的能效差异显著,节能减排潜力巨大;技术进步、经济结构和能源消费结构的优化对促进各地区节能减排有显著作用,而市场化水平、能源价格对节能减排的影响尚不明显。更多还原

【Abstract】 Using CO2 and SO2 emissions as environmental impact’s proxy variables of energy utilization and putting them into the study framework of total-factor energy efficiency,this paper measures China’s provincial total-factor energy efficiency including environmental impact by utilizing C2R-DEA model with the China’s provincial panel data from 2000 to 2007.On the basis of the measurement results,China’s provincial potentials of energy conservation and emissions reduction are calculated.Subsequently,Tobit model is used to test the determinants of energy conservation and emissions reduction in China.The empirical results show the lowlevel of China’s total-factor efficiency and relatively significant differences in energy utilization of all areas and three major regions.Hence,there are large potentials of energy conservation and emissions reduction in China.It is clear that optimizing economic structure and energy consumption structure,as well as technical progress would have remarkable positive influence on energy conservation and emissions reduction,but the influence of the price of energy and marketization is not remarkable.更多还原
