南京市医疗资源空间分布均衡性与可达性研究

Research on Spatial Accessibility and Balance of Medical Resources in Nanjing

基于南京市基础地理信息数据、街道人口数据和医疗机构床位数据,采用两步移动搜索法、基尼系数等方法对南京市医疗资源空间分布均衡性及可达性进行研究。结果表明:南京市医疗资源空间分布不均衡,呈现南北新城区偏低,中部老城区偏高特征,且现有医疗资源难以完全满足常住人口需求,但可基本满足老年人口的需求;步行可达性水平低,驾车可达性水平高,两种出行方式综合就医可达性呈现以老城区为中心,向外围圈层状递减的特征。研究认为应加大老城区和部分新城区的优质医疗资源向周边区域的辐射作用,增加对北部市辖区医疗资源供给,解决医疗资源不均衡分布问题,并通过分级诊疗,构建区域医疗联合体解决步行就医不可达问题。

Based on the basic geographic information data,street population data and hospital beds data of Nanjing,the Two-step floating catchment area and Gini coefficient are used to study the spatial distribution equilibrium and accessibility of medical resources in Nanjing.The results show that the spatial distribution of medical resources in Nanjing is unbalanced,which is characterized by a low level of new urban areas in the north and south and a high level of old urban areas in the central part.Moreover,the existing medical resources cannot fully meet the needs of the permanent residents,but can basically meet the needs of the elderly population.The accessibility level of walking is low,while that of driving is high.The comprehensive medical accessibility of two modes shows the characteristics of stratification decreasing from the old city center to the outer circle.The research suggests that the radiation effect of high-quality medical resources in old urban areas and some new urban areas should be increased to the surrounding areas,solve the problem of unbalanced distribution of medical resources byincreasing the supply of medical resources to the northern municipal districtand build a regional medical complex to solve the problem of inaccessible medical treatment by walking through hierarchical diagnosis and treatment.
