Heterogeneous industrial agglomeration, its coordinated development and total factor energy efficiency.

Based on the panel data of 30 provinces (cities) in China, this paper first measures the total factor energy efficiency, technical efficiency index and technological progress index from 2003 to 2018 by using the DEA-GML index method. Then, a panel Tobit model is constructed to analyze the impact of different industrial agglomerations on total factor energy efficiency and its components. It can be found from the empirical results that the agglomeration of manufacturing industry has no significant impact on the performance of total factor energy efficiency, and the agglomeration of producer services and the collaborative agglomeration of manufacturing and producer services promote the improvement of energy efficiency. Among them, the main way for industrial agglomeration to improve total factor energy efficiency is technological progress, and the promoting effect of technological progress is enough to make up for the inhibiting effect of industrial agglomeration on technical efficiency. Further research finds that the impacts of manufacturing agglomeration, producer services agglomeration and collaborative agglomeration in different regions on total factor energy efficiency are different. Specific suggestions to improve total factor energy efficiency are put forward, such as accelerating the deep integration between industries, improving technological innovation ability, implementing differentiated development strategy, and improving the market mechanism about energy conservation and emission reduction strategies.
