Coupling coordination between urban human settlement environment and economic resilience

With the acceleration of urbanization, urban systems show varying degrees of vulnerability when facing external shocks.Existing studies on urban economic resilience and human settlements are mostly single-dimensional analyses, lacking a systematic evaluation of the coupling mechanism between the two, making it difficult to provide a scientific basis for comprehensive urban governance and coordinated development.To this end, this paper introduces the entropy weight method and coupling coordination model, integrates the multidimensional indicator system and spatiotemporal data analysis method, and establishes a comprehensive evaluation framework with "human settlement environment-economic resilience" as the core, aiming to enhance the ability to fine-tune monitoring and regulation of urban development coordination.Based on the panel data of 31 cities in the middle reaches of the Yangtze River urban agglomeration from 2016 to 2024, an index system with a three-dimensional structure of housing, ecology, culture and education, public services and economic resilience is constructed.The entropy method is used to calculate the weights and obtain the level of human settlement environment and economic resilience.The interaction intensity and degree of coordination between the two are quantified through the modified coupling coordination model.At the same time, Kernel density estimation is introduced to depict the dynamic distribution characteristics and evolution trend of coupling coordination degree, so as to achieve a detailed description of regional coordination differences.The research results show that the overall living environment and economic resilience levels of the Yangtze River Middle Reaches Urban Agglomeration have shown an upward trend during the study period, but there are significant regional differences in the improvement of coordination.Wuhan and Changsha's living environment and economic resilience scores are both at the top of all cities, 0.842 and 0.879, 0.791 and 0.823, respectively, indicating that the two cities have shown strong comprehensive development capabilities in terms of living environment and economic resilience, and the score gap between the two is small, reflecting their high level of coordinated development.
