技术进步对中国电力行业环境效率提升影响的实证研究

TSBM super efficiency model and ML model are adopted to measure the environmental efficiency and its growth rate of China's power industry in 30 provinces from 2009 to 2018 from a static and dynamic perspective, the static efficiency and dynamic efficiency are splitted, and the impact of technological progress on them is analyzed; Using Tobit regression model, the impact of technological progress and other factors on the environmental efficiency and growth rate of power industry in China and six power grid regions is tested. The results show that the annual average environmental efficiency of China's power industry during the study period is 0.769, which still has a large room for improvement; The improvement of pure technical efficiency in Central China Power Grid and Northeast China Power Grid has a low contribution to the improvement of environmental efficiency; The regional pure technical efficiency of China Southern Power Grid has significantly promoted the improvement of environmental efficiency; The environmental efficiency of China's power industry has increased at an average annual rate of 5.6%, of which the average annual growth rate of technological progress is 3.7%. Technological progress has made a great contribution to the improvement of environmental efficiency of China's power industry. Since the 12th Five Year Plan, the technological progress of China's power industry has accelerated; Technological progress is a key factor affecting the environmental efficiency and growth rate of power industry, which has a significant positive impact on it. It is suggested to continue to increase scientific and technological investment and strengthen scientific and technological innovation, so as to continue to promote the improvement of environmental efficiency of China's power industry; All regions should be proactive and take effective measures according to local conditions, accelerate the development of clean electric energy such as nuclear power and optimize the power supply structure.
