目的:实证分析我国城市医疗卫生资源与人口密度之间的标度关系。方法:运用对数线性回归估计标度指数,并比较标度指数的差异性。结果:研究发现医疗服务资源密度与人口密度之间存在普遍性的标度关系,医院密度的标度指数小于1,而床位密度和医生密度的相应标度指数约等于1。分区域的估计显示标度指数存在区域性差异,与经济发展水平有关。结论:我国中西部地区医疗资源仍然相对不足,未来还需要加大对中西部地区医疗服务资源的投入。
Objective: To empirically analyze the scale relationship between urban health resources and population density in China. Methods: The logarithmic linear regression was used to estimate the scale index, and the differences of the scale index were compared. Results: The study found that there is a universal scale relationship between resource density and population density of medical services. The index of hospital density is less than 1 while the corresponding index of index of bed density and doctor density is about 1. Estimates in the subregions show that there are regional differences in scale indices, which are related to the level of economic development. Conclusion: The medical resources in the central and western regions of our country are still relatively inadequate, and the investment in medical service resources in the central and western regions will also need to be increased in the future.
