| 摘 要： | 本文采用综合径向与非径向DEA新技术的EBM模型,在环境质量约束下测度中国时序能源效率。在此基础上,本文通过经验分析EBM能源效率的影响因素与作用机制,发现工业化并不是影响能源效率的主导因素,能源效率与城市化水平呈现出U型变动特征,并且城市化率达到55.46%门限值将为工业企业的产业集聚创造条件,进而通过规模经济改进能源利用效率。此外,由于国际金融危机的外部冲击使得国家节能减排政策并未产生预期效果。

| Abstract: | This paper applies EBM model,the new DEA method,which combines radial and non-radial features to measure energy efficiency of China under the constraint of environmental quality.The dynamic information of EBM energy efficiency shows that energy efficiency of China has experienced twice long-term decline from 1952 to 2010.And then we empirical analysis the influencing factors and mechanisms of energy efficiency.The result indicates that industrialization has not been the dominant factor affecting energy efficiency.Urbanization shows U-shaped relationship with energy efficiency,moreover urbanization can improve energy efficiency by increasing return to scale when urbanization reaches 55.46% it will benefit the agglomeration of industrial enterprises.Furthermore the implementation of national energy saving policy did not realize the desire results due to the international finance crisis. |
