Urban resilience evaluation indicator system.

Enhancing urban resilience is critical for mitigating disaster risks. This study investigates the relationship between digital infrastructure construction (DIC) and urban resilience using panel data from 283 cities in China (2011–2022). Employing constructed indices for DIC and multi-dimensional urban resilience, we empirically analyze the mechanisms and spatial spillover effects of DIC. The study finds: (1) DIC significantly enhances urban resilience, with this positive effect mediated through improvements in critical public services, technological innovation, and resource allocation efficiency. (2) The resilience-enhancing impact of DIC exhibits significant heterogeneity, varying substantially across regions and industrial structures. (3) DIC generates positive spatial spillovers, boosting urban resilience not only locally but also in neighboring regions. These findings provide robust empirical evidence for leveraging DIC as a strategic tool to strengthen urban resilience against disasters.

提升城市韧性对于减轻灾害风险具有关键意义。本研究基于中国283个城市2011—2022年的面板数据，考察数字基础设施建设（Digital Infrastructure Construction，DIC）与城市韧性的关联。本研究通过构建DIC与多维城市韧性的评价指标，实证分析了DIC的作用机制与空间溢出效应。研究结果显示：其一，DIC可显著提升城市韧性，该正向效应通过优化关键公共服务、推动技术创新以及提升资源配置效率实现中介传导；其二，DIC的韧性提升效应存在显著异质性，在不同区域与产业结构下呈现出明显差异；其三，DIC具有正向空间溢出效应，不仅能够提升本地城市韧性，还能带动周边地区的城市韧性水平。上述研究结论为将DIC作为战略工具以强化城市灾害韧性提供了稳健的实证依据。
