Abstract:Health care services are an important part of public services and a focal point for building healthy China. Therefore, the spatial distribution of health services is an important issue of health geography. By establishing a reasonable index system, the annual medical service levels, spatial distribution, and influencing factors in 2004, 2009, and 2014 in mainland China were calculated using factor analysis, standard deviation ellipse, and spatial econometric model. The results showed that: 1) the level of health care services in public hospitals and private hospitals showed obvious characteristics of southeast-northwest differentiation; 2) high-value areas for medical and health services were in economically developed areas such as the Yangtze River Delta and Pearl River Delta, and Sichuan , Henan and other populous provinces, the lower level areas are located in the western regions such as Inner Mongolia Autonomous Region, Qinghai Province and Tibet Autonomous Region. 3) spatial econometric regression model found that the level of residents' consumption, the number of first-class hospitals and the dependency ratio are the important factors that affect the public health services. Public consumption, the number of secondary hospitals, dependency ratio and the incidence of infectious diseases significantly impact on private hospitals. This study is of great significance to the formulation of balanced policies in the area of health care services and to the regional sustainable development of health care services.
