摘　　要：利用标准差椭圆及热点分析等方法探究长三角地区养老设施的演化规律,运用双重差分模型检验一体化政策对各城市养老设施的影响效应与动力机制,基于核心-边缘理论考察该政策对于核心城市与边缘城市影响效应的差异,利用极化指数分析长三角养老设施发展的极化趋势。结果表明:(1)长三角养老设施的空间格局正经历着由高度集聚向广泛扩散的转变;(2)长三角一体化政策带动了城市养老设施的发展,同时该政策对都市圈边缘地区的影响效应相比于核心城市更为显著;(3)区域一体化政策有助于缩小城市间养老设施发展水平的差异性。Utilized methods such as standard deviational ellipse and hotspot analysis to investigate the evolutionary patterns of elderly care facilities in the Yangtze River Delta region.Employing a difference-in-differences model,the study examined the impact and driving mechanisms of integration policies on elderly care facilities in various cities.Furthermore,based on the core-periphery theory,the study examined the differences in the effects of the policy on core cities and peripheral cities.Finally,using polarization index analysis,the study analyzed the polarization trend of elderly care facility development in the Yangtze River Delta region.The research findings indicate that:(1)The spatial pattern of elderly care facilities in the Yangtze River Delta region is undergoing a transition from high agglomeration to broad diffusion.(2)The integration policy in the Yangtze River Delta region has stimulated the development of urban elderly care facilities,and the impact of this policy on peripheral cities is more significant compared to core cities.(3)Regional integration policies contribute to reducing disparities in the development of elderly care facilities among cities.
