本文基于投入产出面板数据,运用SBM超效率模型,客观、合理地评价了我国29个省域1990-2013年的全要素电能效率。运用Tobit模型,探究了我国全要素电能效率的影响因素。实证结论显示:我国全要素电能效率具有显著的阶段性及地域性。实际电价水平、对外开放、外商直接投资、产业结构调整对于电能效率的提高有积极作用;经济发展、政府影响力、城市化对电能效率有抑制作用,同时,各影响因素对不同区域的电能效率作用机制存在一定的差异。
Based on the input-output panel data and the SBM super-efficiency model, this paper objectively and reasonably evaluated the total factor energy efficiency of 29 provinces in China in 1990-2013. Tobit model is used to explore the influencing factors of total factor energy efficiency in China. The empirical conclusion shows that the total factor energy efficiency in our country has significant stage and regionality. The actual electricity price level, opening to the outside world, foreign direct investment and industrial restructuring have a positive effect on the improvement of electric energy efficiency. Economic development, government influence and urbanization have an inhibitory effect on electric energy efficiency. At the same time, the impact of various influencing factors on the energy efficiency There are some differences in the mechanism of action.
