Evaluation and coupling coordination analysis of high quality development of China's coal industry: Empirical research based on data from 2000 to 2019

This paper constructs an evaluation index system for high-quality development of coal industry from six dimensions: economic benefits, innovative development, intensive development, safe development, green development and efficient development.The high-quality development of China's coal industry from 2000 to 2019 is measured and analyzed in depth by entropy method, TOPSIS method and coupling coordination model.The results show that the high-quality development of the coal industry has achieved significant achievement, but the industrial scale is obviously out of sync with the high-quality development level.The main motivation and "short board" of high-quality development of the coal industry is significantly different in different stages of development.The six dimensions of high-quality development of the coal industry have been improved to varying degrees during the research period, but the speed of green development and high-efficiency development is relatively low.The coupling and coordination degree of the six-dimensional development of the coal industry has steadily increased, but has not yet entered the stage of "high-quality coordinated development"and the level of coordinated development needs to be improved.
