了解乡村居民进城就医特征及现状已成为优化城乡医疗资源配置、推动区域协调发展的迫切需要。本文基于长沙市手机定位数据，通过居住地与医院AOI信息识别乡村居民进城就医个体并提取其出行链，分析就医行为的时空特征及空间分异，结合该行为特征改进两步移动搜索法评估乡村居民进城就医可达性。结果表明：(1)长沙市城乡三级医疗资源分配不均衡问题较突出，偏远乡村居民较难满足自身三级医院的就医需求；(2)进城就医热点乡镇主要分布于市区及县中心周边，乡村居民倾向选择距离较近的县中心医院就医，而非城市中心医疗水平最好的医院；(3)乡村居民进城就医可达性呈辐射式分布，越接近城市中心，可达性越好。研究结果可为评估乡村居民进城就医状况、改善乡村居民医疗服务体验提供参考。
Abstract：With the growing public demand for high-quality medical services, understanding the characteristics and current status of rural residents′ medical care-seeking in urban areas has become imperative for optimizing the allocation of medical resources between urban and rural regions and promoting coordinated regional development.This study uses mobile phone location data from Changsha to identify rural residents based on their place of residence.Travel chains of these residents are then extracted, and individuals seeking medical care in urban areas are identified using hospital AOI(Area of Interest) information.Spatiotemporal patterns and spatial heterogeneity of rural residents′ medical care-seeking behavior in urban areas are analyzed.Furthermore, based on these behavioral characteristics, the two-step floating catchment area(2SFCA) method is improved to evaluate the accessibility of urban medical services for rural residents.It is found as follows.(1) The distribution of tertiary healthcare resources between urban and rural areas is significantly imbalanced, making it difficult for residents in remote villages to access the tertiary hospital services.(2) Townships with high-frequency access to urban medical services are mainly located around urban districts and county centers.Rural residents tend to choose closer hospitals in county centers rather than the best hospitals in urban districts for medical services.(3) The accessibility of urban medical services exhibits a radial pattern, with townships closer to the city center generally demonstrating better accessibility.This study provides a reference for assessing rural residents′ access to urban medical services and improving their healthcare experiences.
