Abstract

Coal-based thermal power generation has long been the main source of power generation in the mainland of China. The efficiency of power generation is an important factor that determines the energy conservation and emission reduction as well as the sustainable development of the power industry in China. By comparing the regional differences of 30 provinces in the mainland from 2013 to 2017, this study uses the Super-DDF model and the TFEE to comprehensively evaluate the energy efficiency of thermal power generation. Empirical results: Overall efficiency: eastern efficiency (1.181) is the highest, followed by western (0.956), central (0.951) and northeastern (0.926). Total factor energy efficiency: eastern efficiency (0.923) is the highest, followed by western (0.754), central (0.742) and northeastern (0.710). The government and power industry managers should fully consider the regional differences in the field of thermal power generation when formulating policies so as to improve the power efficiency and promote the green development of power industry in China. Based on the analysis results, although the coal-fired power industry is more mature than other alternative energy industries, the expansion of thermal power generation cannot be considered if CO2 emissions are to be reduced. Additionally, the market share and competitiveness of the local power industry can be increased based on the different conditions of the resource endowments of each region.

Summary

Introduction

In the past few decades, China’s increasing power demand and heavy dependence on coal-fired power generation have resulted in severe air pollution problems in. In the neighboring countries, such as Japan and South Korea. Experts call on the Chinese government to take effective environmental protection measures as soon as possible to curb the possible negative effects of air pollution on its environment and its people’s health. With the rapid economic growth, a large number of coal-fired power plants have been built across China in recent years to cope with the power shortage. Experts point out that the high dependence on coal-fired power generation has meant China’s air pollution problems continue to worsen and may even affect its neighboring countries. The Chinese government must act as soon as possible to reduce the rate of environmental degradation
