Abstract

Energy consumption emits large amounts of greenhouse gas, which exacerbates the problem of global warming. In order to slow down the rate of global temperature rise, improve green energy efficiency and achieve high-quality economic development, it is necessary to measure green energy efficiency accurately. By means of the Super-SBM model, this paper calculates the total factor green energy efficiency of 30 Chinese provinces from 2010 to 2017(except Tibet, Hong Kong, Macao and Taiwan), and analyzes it from the perspective of industrial structure and region. The results show that the optimization and upgrading of the secondary industry contributes to the improvement of green energy efficiency. On the whole, the green energy efficiency is declining, with remarkable regional differences: The eastern region is higher than the western region, while the western region is higher than the central region. And excessive greenhouse gas emissions in the central region are the main cause of its low green energy efficiency.
