医疗卫生资源对医院创新的空间溢出效应研究

Research on the Spatial Spillover Effects of Medical and Health Resources on the Hospital Innovation

目的研究中国省际卫生资源对医院创新的影响与空间溢出效应。方法基于2000—2014年31个省份的面板数据,以各省份医院专利数量表示医院创新并作为被解释变量,以各省份医疗机构床位数、人均GDP、医疗卫生支出等变量作为解释变量,运用面板空间杜宾的计量方法分别对全部省份,东部、中部、西部省份进行回归。结果医疗卫生资源不仅对本省份医院创新有显著的促进作用,而且还会显著影响相邻省份的医院创新,即存在溢出效应;本省份医疗资源对本省份和邻省份医院创新的促进效果大体相当;东部、中部省份医疗资源对本省份医院创新作用显著,中部省份存在溢出效应。结论进一步增加医疗卫生资源投入,搭建省际之间资源与创新交流平台,促进东、西部省份溢出效应的提升,以推动供给侧改革。

Objective To study the spatial spillover effects of medical and health resources on the hospital innovation. Methods Based on panel data of 31 provinces of China from 2000 to 2014, and with the method of Spatial Durbin Model（SDM）, the paper does the regression with the sample of all provinces, eastern, central and western provinces, through using provincial patent number as explained variable, and using the provincial medical institutions of beds, per capita GDP, health care spending as explanatory variables. Results Medical and health resources have a significant role in promoting the hospital innovation, not only for local province but also for adjacent provinces, namely there is spillover effect; the promotion effect of medical resources for local and neighbouring province hospital innovation is almost same; for eastern and central provinces, there is a positive effect of medical resources to hospital innovation, and for central province, the spillover effects exist. Conclusion The medical and health resources should be further increased, a provincial communication platform of resources and innovation be built, the east and western provinces spillover effect be promoted, to drive the reform of the supply side with innovation.
