| 摘 要： | 采用定基极差熵权法与定基等权赋值法相结合的综合评价方法、核密度估计、探索性空间数据分析等方法,分析2003—2018年中国284个地级以上城市公共健康水平的时空演化特征,并运用广义空间两阶段最小二乘法考察其影响因素。结果发现：① 研究期内中国城市公共健康水平整体呈上升趋势,但各城市间公共健康水平差异有所扩大,且始终存在多级分化现象;② 四大板块核密度曲线在重心位置、主峰高度、波峰数量、拖尾长度、拖尾厚度上均有各自演化形态,是一种时段特征与地区特色相互耦合叠加的结果;③ 中国城市公共健康水平存在正向空间溢出效应和空间“同群效应”,空间集聚类型实现了由LL型为主体向HH型为主体的转化;④ 收入水平、人口密度、科技进步、工业化程度、卫生体制改革对城市公共健康具有影响,但各因素对不同区域的影响存在异质性。

| Abstract: | Based on the comprehensive evaluation method combining fixed base range entropy weight method and fixed base equal weight assignment method, kernel density estimation and exploratory spatial data analysis methods, this paper analyzes the spatio-temporal evolution characteristics of public health level of 284 cities in China from 2003 to 2018, and uses the generalized spatial two-stage least square method to investigate its influencing factors. The results show that: (1) During the study period, the urban public health level is on the rise as a whole in China, but the difference of public health level among cities has expanded, and there is always a phenomenon of multi-level differentiation. (2) The kernel density curves of the four plates have their own evolution forms in the position of gravity center, the height of main peak, the number of wave crests, the length of trailing and the thickness of trailing, which is the result of the coupling and superposition of time characteristics and regional characteristics. (3) There are positive spatial spillover effect and spatial “Peer Effects” in China's urban public health level, and the spatial agglomeration type has transformed from LL type to HH type. (4) Income level, population density, technological progress, industrialization and health system reform have an impact on urban public health, but the impact of various factors on different regions is heterogeneous. |
