目的:研究2009年医改前后医疗机构投入对服务效率的影响,并探讨这种影响的区域差异性。方法:通过主成分分析法(PCA)合成医疗机构投入综合指标和服务效率综合指标,采用动态面板回归方法分析医疗机构投入对服务效率的影响,分区域进行回归探讨区域间的差异性。以2009年医改为时间截点采用断点回归法分析医改前后这种影响的变化。结果:总体上,医疗机构的粗放型投入对医疗机构服务效率的影响是起抑制作用的,但是医改后这种抑制作用却不再显著,反而在西部地区有促进作用。结论:医改给各地区的投入效率转换带来了契机,这种改革红利效应在西部地区最为明显。管理层和政府政策制定者需要认真贯彻医改的有关要求,提高投入对服务效率的转化率,从而更好的为广大的人民群众提供安全、有效、方便、价廉的医疗卫生服务,促进我国公共卫生事业的有序发展。
Objective: To study the impact of medical institutions’ input on service efficiency before and after the medical reform in 2009 and to explore the regional differences of such impact. Methods: The principal component analysis (PCA) was used to synthesize the comprehensive index of medical institutions and the comprehensive index of service efficiency. The dynamic panel regression method was used to analyze the impact of medical institutions’ input on service efficiency. Subregional regression was used to explore the regional differences. Taking 2009 medical reform as the time cut-off point, the break-point regression method was used to analyze the changes before and after the medical reform. Results: In general, the extensive input of medical institutions has an inhibitory effect on the service efficiency of medical institutions. However, the inhibitory effect after medical reform is no longer significant. On the contrary, it has a catalytic effect in the western region. Conclusion: The medical reform has brought opportunities for the transformation of input efficiency in all regions. This kind of reform bonus effect is most obvious in the western region. Management and government policymakers need to conscientiously implement the relevant requirements of medical reform and improve the conversion rate of input into service efficiency so as to provide safe, effective, convenient and affordable medical and health services to the general public and promote public The orderly development of health care.
