Abstract
Abstract This paper put forward a method to promote low-carbon development of electric power industry in China from the perspective of benchmarking circular economy efficiency of coal-fired power plants. The input-output index system that reflects reducing, reusing and recycling carbon dioxide, waste and pollution emissions for measuring the circular economy efficiency of coal-fired power plants is set up. With the survey data of 24 coal-fired power plants, the superefficiency data envelopment analysis (DEA) model is applied to ranking and improving the circular economy efficiency of these plants. And the benchmarking is carried out using the aforesaid DEA model. The benchmarking procedure proposed in this paper can be used to choose the best efficiency benchmark of circular economy in the environmental management of power plants and enhance the low-carbon development of coal-fired power industry.
