Measurement and Spatial Evolution of Regional Energy Efficiency in China

Energy is an important factor of production to ensure sustainable development of country. There are obvious regional differences in energy efficiency in China at the present stage. In this context, this paper studies the provincial energy efficiency in China. Under the framework of total factor energy efficiency analysis, the total factor energy efficiency of 30 provinces (cities and autonomous regions) in China from 2007 to 2016 is measured by means of the global super-efficiency SBM-DEA model. Further, this article is based on the space perspective, with the aid of spatial econometric theory and methods, to the Chinese provincial total factor spatial correlation of the energy efficiency test, the results show that there are provincial total factor of energy efficiency in the space since the correlation of the regional difference of China's total factor energy efficiency analysis and put forward the corresponding countermeasures.
