Therefore, it is necessary to study the impact of trade liberalization on energy efficiency through technological progress. Firstly, this paper analyzes the current situation, mechanism, concept definition and theoretical analysis of trade liberalization and technological progress on energy efficiency by using the existing relevant literature and relevant official data. Secondly, according to the actual situation of China's energy efficiency, trade liberalization and technological progress and the mechanism analyzed above, the energy efficiency values of 30 provinces in this paper from 1995 to 2019 are calculated based on the Global Malmquist Luenberger (GML) index, so as to provide factual basis for the following empirical research and policy recommendations. Thirdly, the mediation effect model is constructed, and the mediation effect is tested the relationship among trade liberalization, technological progress, and energy efficiency. Then, regional heterogeneity research and robustness test are carried out. This paper discusses the impact of the differences between the east, west, north and south parts of China on the empirical results and tests the robustness of the influence path of technological progress on energy efficiency and the reliability of the regression results. Finally, according to the empirical results, this paper summarizes and puts forward some policy suggestions for promoting the coordinated development between China's energy efficiency and comprehensive opening up.}, pages = {3--24}, title = {Trade Liberalization, Technological Progress and Energy Efficiency Improvement in China}, volume = {14}, year = {2023} }
