合理配置医疗资源是加快医疗体系建设的重要基础和内在要求,研究自然和经济社会因素对医疗资源配置的影响,可为医疗服务体系科学规划和建设提供有力支持。本文以2000—2002年、2005—2007年、2010—2012年3个时期的四川省区县公立医院床位数为例,利用空间分析技术研究了区县床位的时空变化特征,并采用地理加权回归模型方法解释了经济、人口、交通、地形等因素对其时空异质性的影响。结果表明:2000—2012年,川东地区的床位数总体高于川西高原,在区县尺度呈现显著的空间聚集性分布特征(3个时期的漠然指数分别为0.16、0.15、0.18,p<0.01),其时空异质性与地形、人口、经济及交通等因素关系密切,且地形起伏度、人口、交通要素在川西高原影响尤为明显。因此,应依据四川省医疗水平的现状和驱动因子的效应机理,因地制宜规划和建设医疗卫生服务体系,促使其平衡发展,以提高医疗卫生基础设施对居民健康的保障能力。
Rational allocation of medical resources is to speed up the construction of the medical system an important foundation and internal requirements to study the impact of natural and economic and social factors on the allocation of medical resources can provide scientific support and medical science system planning and construction. Taking the number of beds in public hospitals in districts and counties of Sichuan Province during 2000-2002, 2005-2007 and 2010-2012 as an example, spatial and temporal analysis of the spatial and temporal variations of beds in counties and counties was conducted. The model method explains the impact of economy, population, traffic and topography on its spatio-temporal heterogeneity. The results showed that in 2000-2012, the number of beds in the eastern part of Sichuan was higher than that in the western Sichuan Plateau, and the distribution of spatial distribution was significant at the county scale (the indifference indices were 0.16, 0.15, 0.18, p <0.01 ). Its temporal and spatial heterogeneity is closely related to the topography, population, economy and traffic. The topographic relief, population and transportation elements are particularly evident in the western Sichuan plateau. Therefore, we should plan and construct the medical and health service system in line with the current situation of medical treatment in Sichuan Province and the effect mechanism of drivers, and promote balanced development so as to improve the health and medical infrastructure’s ability to guarantee the health of residents.
