Structural differentiation and collaborative optimization of the spatial network of pension care service in megacity behemoths: a case study of Guangzhou, China
Year: 2026
Type: article
Abstract: Introduction: Against the backdrop of population aging, cross-district coordination and equitable allocation of pension care resources have become increasingly important for improving service accessibility and urban governance in megacities. This study examines spatial disparities and interdistrict connections in pension care services across Guangzhou's 11 districts, focusing on resource distribution, transportation accessibility, and network structure. Methods: A multidimensional evaluation framework encompassing institutional care capacity, home- and community-based care capacity, and medical support capacity for pension care was developed. The entropy weighting method was employed to evaluate the comprehensive development level of pension care services in each district. An interdistrict transport impedance index was constructed based on public transportation travel times, and a modified gravity model was applied to estimate the strength of interdistrict connections in pension care services. Social network analysis was subsequently conducted to examine network density, centrality, and core-periphery structures. Results: The findings reveal substantial spatial disparities and functional differentiation in pension care services across Guangzhou. Transportation accessibility generally decreases from central to peripheral districts. The interdistrict service network exhibits a centralized and hierarchical structure, with Baiyun and Tianhe occupying prominent positions in network connectivity. Liwan, Tianhe, and Baiyun constitute the network's core area, whereas peripheral districts demonstrate relatively weak interdistrict connections and insufficient coordination. Discussion: The findings underscore the need to strengthen cross-district coordination and address spatial inequalities in pension care services. Policy priorities include enhancing resource integration and service coordination among core districts, developing secondary pension care service centers, and improving mechanisms for resource sharing, service referral, and digital collaboration in peripheral districts. These measures could contribute to a more balanced, multi-tiered, and interconnected urban pension care service network.
