Against the background of regional integration process and increasing urbanization level, the formation of highly integrated development regions like city clusters has greatly facilitated the medical resource synergy among cities, which significantly affects the regional medical resource security required for sustainable regional development and response to disaster attack. Improving regional resilience requires ensuring medical resources with a more rational spatial distribution and its synergistic development commensurate with economic and demographic development. Therefore, to further analysis medical resource security resilience of city cluster region, this study proposes a balanced approach including the perspectives of equilibrium of each city, the city network structure layout and recovery ability under disaster. With the case study of Yangtze River Delta (YRD), Pearl River Delta (PRD) and Beijing-Tianjin-Hebei (BTH), we comprehensively measure the regional medical resources security resilience from spatial distribution and temporal evolution perspectives. The results reveal that in spatial distribution perspective, the synergy intensity among cities in PRD is significantly highest, while in YRD is the most balanced. In addition, Beijing shows greatest medical impact in BTH. For temporal evolution perspectives, PRD and BTH show the tendency of medical resource synergy driven by core cities, while YRD create the multi-subscale synergies. •Explore the synergy among cities for medical resource security under the city network system.•Introduc a new methodology of constructing a regional synergistic network of city interactions from a relational perspective and bridge the gap in quantitative research on cross-city medical resource security.•Evaluate regional medical resource security resilience from multiple perspectives of network analysis methods, enriching the methodological indicators of regional resilience study.•Making comparisons of regional medical resource security resilience among YRD, PRD and BTH in perspective of spatial distribution and temporal evolution, revealing the current developing state and future improvement trends of each city cluster region.
