Spatial-time evolution of EES coordinated development in coal mining subsidence area of Shanxi Province

Based on the coordinated development and panel data model, this paper constructs the "ecological economic social" (EES) system index system of coal mining subsidence area in Shanxi Province, from the perspective of time and space combined with entropy method and analytic hierarchy process, analyzes the coordinated development evolution rules of EES system in coal mining subsidence area of Shanxi Province from 2004 to 2018.The results show that the economic subsystem accounts for the highest proportion in the EES system, which indicates that the development of economic subsystem has the greatest influence on the coordinated development of EES system in coal mining subsidence area of Shanxi Province; the coordinated development of EES system in coal mining subsidence areas of Shanxi Province shows a steady upward trend on the whole from 2004 to 2018, and the coordinated development level of EES system in various cities in the region gradually transited from "serious imbalance recession" to "barely coordinated development", from "maladjustment recession interval" to "transition and harmony interval"; in terms of spatial distribution, the coordinated development and evolution process of EES system of cities with higher economic development level in the region is relatively advanced.Finally, according to the research results, the corresponding countermeasures and suggestions are put forward.
