Environmental sustainability in polycentric urban regions: an urban resilience perspective
从城市韧性理论出发，构建区域环境可持续性指数，分析中国城市区域的多中心结构对环境可持续性的影响，发现形态多中心性有正面作用，而功能多中心性仅对环保公共管理有积极影响。
Regional studies research examining the environmental impacts of polycentric urban structures is often called for, but remains scarce. This study uses urban resilience theory to conceptualise, methodologically specify and empirically assess the effects. We develop an evaluation system to establish a regional environmental sustainability index and apply it to urban regions across China. Gridded population datasets and inter-city co-patent data proxy morphological and functional polycentricity. Results show that morphological polycentricity positively impacts environmental sustainability, while functional polycentricity only positively affects public stewardship in environmental protection. Urban resilience attributes such as diversity and flexibility have uneven explanatory power on these dynamics.
