[Abstract] 

  This study’s key finding is that compound disasters do not exert a monolithic impact; rather, their effect on urban systems is profoundly shaped by the unique spatial characteristics of each constituent crisis. The stark contrast between the spatially asymmetric shock of COVID-19 and the homogeneous influence of extreme temperatures strongly supports the hypothesis that different types of disasters require fundamentally different response strategies. These findings have critical policy implications. The inadequacy of one-size-fits-all national policies is clear. For powerful, unpredictable, and spatially heterogeneous shocks like a pandemic, a decentralized, adaptive, and place-based approach is essential. This requires empowering local governments with the authority and real-time data needed for rapid, tailored interventions. Conversely, for predictable and spatially homogeneous threats like seasonal heatwaves, standardized national guidelines and infrastructure investments remain effective and efficient. This research provides empirical evidence for a dual-response framework that differentiates strategies based on a disaster’s spatial signature, ultimately fostering more effective and equitable urban resilience in an era of increasingly complex crises.
