Evaluation of the Transformation Effect of Coal Resource Depleted City in Jiaozuo City Based on the CRITIC-VIKOR Method

This paper uses the CRITIC-VIKOR method to comprehensively evaluate Jiaozuo City, a typical coal resource depleted city, from four dimensions: environmental, economic, social and resource. By analyzing the relevant data from 2009 to 2023, this paper analyzes the transformation effects of each subsystem, aiming to provide theoretical basis and practical reference for the transformation and development of coal resource depleted cities.The results revealed that Jiaozuo achieved its lowest score of 0.36 in 2020, indicating a "relatively good" transformation status (Level IV) and the most effective transformation performance. Conversely, in 2012, it recorded the highest score of 0.82, corresponding to a "poor" transformation status (Level I) and the least effective performance. Socially, the best outcomes emerged around 2015, while economic improvements began in 2016. Environmental performance scores hovered around 0.5 with relatively stable fluctuations, peaking in 2014–2015. Resource-related transformation showed positive effects starting in 2020.Comparative analysis across dimensions revealed the following hierarchy: economic > social > environmental > resource.
