Analysis Of the Network and Influencing Factors of Urban Resilience: A Case the Chengdu-Chongqing Urban Agglomeration

As a national strategic growth pole, the urban resilience of the Chengdu Chongqing urban agglomeration is related to regional coordination and national security. Based on panel data from 16 cities from 2009 to 2023, entropy weight method, kernel density estimation, social network analysis, and geographic detector were used to explore the spatial correlation characteristics and influencing factors of resilience. Research has found that resilience has improved across the entire region, but at multiple levels of differentiation, with a spatial pattern of "dual core aggregation edge diffusion" and "high outside and low inside" concentric circles; The interconnected network continues to strengthen, the core edge structure weakens, Chongqing and Chengdu dominate resource flow, and the emerging hub transmission function is beginning to emerge, but there are isolated nodes disconnected. Although cohesive subgroups have shifted from fragmentation to functional collaboration, weak connections between subgroups constrain collaborative efficiency. Geographic detectors show that economic, social, and natural factors affect the level of urban resilience, with social and economic interactions having the most significant impact, while natural factors have a weaker direct influence.
