Abstract：Coal enterprises can energy support for the development of social economy and play an important role in promoting the transformation of China's energy structure.Using the three-stage DEA-Malmquist index method to analyze the development efficiency of major coal listed enterprises form 2011 to 2022 from static and dynamic dimensions.The results show that environment and random disturbance have a great impact on the development efficiency of coal enterprises.The development efficiency of coal enterprises is greatly influenced by the coal market situation,the development efficiency of coal enterprises from 2011 to 2017 was only 0.666,and the average production efficiency of coal enterprises from 2017 to 2022 was 1.151,with an average annual growth rate of about 3％.Technological progress is the main driving force to improve development efficiency of coal enterprises.The main reason for the low production efficiency of coal enterprises is the small-scale efficiency.The development efficiency and resilience of state-owned coal enterprises are significantly higher than those of local coal enterprises.According to the empirical results,some policy recommendations are proposed to improve the development efficiency of coal enterprises.
