Abstract: Coal chemical industry is one of the main ways of clean utilization of coal.Orderly and standardized development of coal chemical industry is an important task of supply-side reform of coal industry in China.The development of China's coal chemical industry has a good foundation and great potential, and some fields have taken the lead in the world.However, there are some disputes, and the unscientific regional layout is one of them.It is that the analysis of the regional competitiveness of industrial layout is not deep enough.This paper collects 12 index data of resource endowment, market competitiveness, infrastructure, economic benefit, environmental capacity and policy support for the development of coal and chemical industry in 31 provincial administrative regions of China.The analytic hierarchy process is used to quantitatively analyze the regional competitiveness of coal chemical industry in each province.According to the level of competitiveness, 31 provincial administrative regions in China are divided into five types of regions, and on this basis, some suggestions on the layout of coal chemical industry in China are put forward.Provinces and regions with rich resources, high environmental capacity, strong local policy support and no bottleneck of water resources, such as Inner Mongolia, Shanxi and Xinjiang, should be given the priority as the key areas for the development of coal and chemical industry.
