Can Regional Integration Enhance Urban Resilience? Based on a Multidimensional View of Urban Resilience
Regional integration, as a critical national strategic policy and a mechanism to drive regional development and cooperation in China, can effectively stimulate urban development and enhance urban com-petitiveness. Therefore, investigating the impact of regional integration on urban resilience provides valuable insights for further improving cities' abilities to cope with diverse risks.This paper employs a multi-period DID approach to examine the impact of regional integration, with a fo-cus on urban cluster planning as a form of quasi-natural experiment, on the level of urban resilience. The re-search explores the heterogeneity and mechanisms of this impact. The findings reveal that: (1) Regional integ-ration significantly enhances the level of urban resilience. (2) The effectiveness of regional integration in im-proving urban resilience is more pronounced in the eastern regions, super-large cities, and polycentric cities. (3) Regional integration enhances urban economic resilience through the structural optimization effect, and urban economic resilience and social resilience through the diversity effect. However, it weakens urban ecolo-gical resilience through the scale effect and has no significant impact on urban engineering resilience. Import-antly, the enhancing effect of regional integration on urban economic resilience and social resilience out-weighs its weakening effect on urban ecological resilience.This paper makes several potential contributions: First, by integrating the essence of resilience, a compre-hensive and scientifically sound indicator system for urban resilience is constructed across four dimensions. Second, by taking multiple national-level city clusters as the research object, regional integration and urban re-silience are directly included in the same framework, enriching the relevant literature on this topic. Third, based on various dimensions of urban resilience, it investigates the mechanisms through which regional integ-ration affects each dimension, providing empirical evidence and policy recommendations for the government to formulate regional integration strategies to promote urban development.
