Digital economy, spatial correlation and urban economic resilience
摘要
This study explores how spatial network structures shape urban economic resilience, emphasizing the role of digital economic interconnections. It expands the literature on digital economy spillovers and contributes to the theoretical understanding of resilience in urban systems. Practically, the study identifies collaborative advantages in core cities and structural vulnerabilities in peripheral ones, informing the design of regional digital cooperation networks. Policy-wise, it offers empirical support for bridging the digital divide and promoting coordinated, high-quality digital development. The study analyzes panel data from listed firms and macroeconomic indicators across 188 Chinese cities from 2011 to 2021. Using social network analysis, it characterizes digital spatial linkages and examines their effects and transmission mechanisms on economic resilience. Key findings are fourfold. First, digital economic connections have intensified over time, yet exhibit a pronounced “Matthew effect,” reflecting persistent regional disparities. Second, spatial digital linkages significantly enhance urban resilience, a conclusion robust to multiple tests. Third, these effects operate primarily through improved innovation quality, reduced resource misallocation, and stronger human capital. Fourth, the resilience impacts vary by city characteristics, highlighting heterogeneous effects. These findings have important implications for strengthening cities’ capacity to withstand economic shocks.
