Resilience construction is of great significance to the sustainable transformation of resource cities. Based on the symbiosis theory, the article constructs the analysis framework of "production-life-ecological resilience", takes 26 resource cities in the Yangtze River Economic Belt as examples from 2017-2022, and uses the G1-CRTIC-VIKOR model to measure the spatial-temporal resilience of resource cities in the Yangtze River Economic Belt, based on the evolutionary characteristics of the resilience. On the basis of the evolutionary characteristics of the resource cities in the Yangtze River Economic Belt, the study explores the spatial correlation structure and correlation characteristics of the resource cities' resilience by using the social network analysis method, and finally analyses the driving mechanism of the resource cities' resilience by using the geographic detector. The study finds that: (1) the ecological resilience, production resilience and life resilience of the resource cities in the Yangtze River Economic Belt in the study area show a general trend of gradual enhancement, but the spatial differences in the resilience of the three lives are obvious. (2) The network density of three-generation toughness of the resource cities in the Yangtze River Economic Belt in the study period has increased significantly, in which the network density of ecological toughness is higher than that of production and life toughness, but the whole is in a weak connection state; the centrality of the point degree of the three-generation toughness and the proximity to the centrality of the three-generation toughness have grown significantly, and the intermediate centrality of the three-generation toughness has been decreasing, in which the ecological toughness centrality has increased at a faster rate than that of production and life toughness. (3) Resource-based city toughness is driven by multiple internal and external disturbances. Therefore, optimising the network structure of resource cities in the Yangtze River Economic Belt and synergistically promoting the development of production, life and ecological resilience in resource cities in the Yangtze River Economic Belt is an effective path to shorten the regional differences and realise the regional symbiotic network.
