With the continuous development of China's economy since the reform and opening up, the total amount of energy consumption in China has been growing. Among them, coal plays a leading role in the total energy consumption by virtue of natural resource endowment and price advantage. However, in recent years, the environmental problems caused by coal mining and utilization, such as vegetation destruction, ecological environment pollution, and increasing greenhouse gas emissions, have become more and more serious, which proves that it is not sustainable to rely on coal based energy structure to support economic development. Therefore, to change the mode of economic growth and energy consumption has become an urgent problem in China. As the gathering place of industrial industry, cities benefit from the promotion of industrial development. Except for the energy consumed by a few residents, almost all of the energy is put into the daily operation and production of the city. Therefore, studying the policy of controlling the total coal consumption from the perspective of the city is conducive to our bottom-up, point-to-face view of the problem, analysis of the impact of the heterogeneity of different cities on the total coal consumption, so as to more in-depth analysis of the coal consumption situation and utilization level of different cities.
