Evaluation and Influential Factor of Regional Total Factor Energy Efficiency in China

There are big gaps in total factor energy efficiency among all regions of China, high in the east to low in the west. The difference between the eastern part and the mid-western part is expanding, while the difference between the middle and western region decreases. In terms of different regions, the total factor energy efficiency in the eastern district greatly diverges, and it continues to shrink in the mid-western part. Technical level, openness and industrialization level of the region play a positive effect on improving the total factor energy efficiency, while the regional ownership structure negatively influences the development of the total factor energy efficiency
