Evaluation Research on the Circular Economy Efficiency of the Coal Industry Based on Dea Model


Abstract

The coal industry plays a very important role in the process of economic development in China. The efficient operation of the coal industry chain is the important foundation for the development of coal circular economy. In this paper, we mainly discuss the three types of coal industry chains, and establish a model to measure the efficiency of the coal industry chain based on the DEA theory. Then by using the coal industry data from 28 provinces and cities nationwide during 2012-2015, we measure the efficiency of the coal industry chain in China. The results show that the efficiency of the national coal industry chain during 2012-2015 was on steady increase, and that the pure technical efficiency is the main factor affecting the efficiency of the coal industry chain in China.
