Why do some cities show greater resilience than others within the same estuarine delta region? While many studies have identified the factors of urban resilience, few have examined how these factors interact to produce resilient outcomes under different local conditions. This study proposes a two-pronged methodology combining calculation and explanation to explore the mechanisms shaping resilience in estuarine delta cities. Using data from the Yangtze River Delta (YRD), this study integrated fuzzy-set Qualitative Comparative Analysis (fsQCA) and Necessary Condition Analysis (NCA) to identify not only the main drivers but also the specific configurations through which resilience develops. The spatial clustering of urban resilience revealed a geographically concentrated pattern of resilience performance, highlighting significant differences in institutional response and development paths across cities. Additionally, it found that industrial transformation and environmental governance are vital for improving urban resilience. Four distinct yet equally effective development pathways have been identified: Multidimensional Collaborative, Infrastructure-Economy Dominant, Green Development, and Livable Economy-Supported. Each pathway aligns with specific city profiles and capacity conditions. This work offers a practical and adaptable framework for building resilience in delta megaregions, supporting context-sensitive policy design that addresses structural and systemic urban vulnerabilities.
