“+ 二五”时期中国能源全要素生产率研究.

This paper deals with regional energy efficiency and energy total-factor efficiency (TFE) indexes in China using weighted Russell directional distance function. We find the differences in inefficiency values among regions in China are significant. Then, we decompose the gross inefficiency term to energy inefficiency values and other indicators' inefficiency, and we find that the inefficiency values of energy are not big. This means that the main sources of inefficiency are not, energy inefficiency. Finally, we analyze the growth in energy total-factor efficiency index and find most of provinces were positive, which indicates that the growth of energy efficiency have positive effects on TFE in provincial economies.
