中文摘要：
将发展经济学家缪尔达尔开创的＂扩散—回流＂效应移植到能源经济学领域,运用全局DEA和SBM方向性距离函数测算了环境约束下的能源效率,从静态和动态视角出发,构造空间计量模型,实证检验了地区间能源效率的空间交互效应。研究显示,地区间能源效率存在着显著的空间交互效应,并且表现为空间扩散效应,即相邻地区的能源效率有利于促进本地区的能源效率。此外,一个有趣的发现是,2006年政府节能减排政策是助推能源效率空间扩散效应的有力抓手,带来＂额外红利＂。因此,要正视区域间能源效率发展差异的事实,能源效率较低的地区应充分利用扩散效应,突破区域间发展的非平衡性,使得能源效率走向＂新古典收敛＂成为可能。
英文摘要：
Starting from inherent properties of energy efficiency, this paper identifies the spatial interaction of energy efficiency through transplanting ＂spread effect-backwash effect＂pioneered by development economist Myrdal to the fields of energy economics. Firstly, this study estimates China＇s provincial energy efficiency with the application of global DEA and SBM directional distance function. To test the spatial interaction of energy efficiency, this paper then constructs spatial econometric models from both static and dynamic perspective.Empirical results indicate that there is significant spatial spread effect between provinces. That＇s to say, an increase in energy efficiency in one province is beneficial to the promotion of energy efficiency in its neighbors. An additional interesting finding is that the＂energy-saving and emission reduction＂policy implemented since 2006 powerfully has been driving spatial spread effect of energy efficiency and bringing＂extra bonus＂. In response, these energy inefficient provinces should face the difference in the development of energy efficiency and make full use of this spread effect to break the regional development imbalance, making the＂neoclassical convergence＂of energy efficiency possible.
