A Malmquist Index-Based Dynamic Industrial Green Efficiency Evaluation in Sichuan Province

In this paper, the DEA-Malmquist index is used to evaluate the industrial green efficiency of 18 cities in Sichuan province during 2008-2014. The study found that in the overall level, the industrial green efficiency of Sichuan prefecture level cities' is low, but it is growing year by year in recent years. The technical efficiency index grows rapidly, and the technological progress index weakened the role of technical efficiency. Industrial green efficiency of Chengdu Plain economic zone is the highest in the four economic zones, followed by the Panxi economic zone, South Sichuan economic zone, lowest in Northeast Sichuan economic zone. Industries need to increase the intensity of the green transformation in Sichuan province.
