Factor Analysis Method of Energy Consumption Intensity Variation Based on Super-Efficiency DEA and its Application

Abstract

Energy is an essential material basis for the development of industry and national economy. The problem of excessive energy consumption caused by the rapid growth of energy in my country has always been a concern of academic circles. Serious energy consumption, low utilization efficiency and the resulting environmental pollution problems make the contradiction between economic growth and energy shortage more and more prominent. So as to solve the increasingly severe environmental and economic development problems caused by excessive energy consumption(EC), it is imperative to reduce the intensity of EC. In this regard, this paper analyzes the factors that affect the change of EC intensity, and introduces the SE-CCR model and SE-BCC model of super-efficiency DEA. It is concluded that the EC intensity can be reduced from the perspectives of adjusting the energy structure(ES) and improving the level of energy research and development.
