Economic resilience is an adaptively dynamic adjustment ability,which can reflect the economic transformation ability of resource-based cities.From this perspective,to classify its types and conclude the transformation law are important means for accurately promoting the economic transformation of resource-based cities.Therefore,this paper constructs a framework for analyzing the resilience of the economic transformation of resource-based cities.Taking 30 coal cities from 2003 to 2019 as examples,their economic transformation capabilities were evaluated,their economic transformation capabilities were divided based on the differences of obstacle factors,and then their transformation rules were summarized.The results show that:1)The economic transformation ability of coal cities varies greatly,and the lack of adaptability and innovation is an important reason for the weak economic transformation ability of coal cities.2)The economic transformation ability of coal cities can be divided into four types.More than 86%of coal cities belong to the type of high adaptability barrier-low innovation barrier or low adaptability barrier-high innovation barrier,indicating that most coal cities are restricted by single factor.3)The type of coal cities with high barriers to adaptation and innovation is easily con-verted into the type of coal cities with high barriers to single factors,and the type of coal cities restricted by sin-gle factors basically remains unchanged,while the type of coal cities with low barriers to adaptation and innovation is unstable and prone to rebound.It can be seen that the economic transformation of coal cities is not achieved in short time,and it is necessary to reduce the obstacle degree for different types and gradually promote the economic transformation.
