本文首先运用DEA方法测量了我国1994—2007年农村医疗卫生财政投入的效率,发现其不仅逐年递减,而且各地区之间的差异不断缩小,呈现逐步趋同的态势。在此基础上通过建立面板数据及其非线性门槛模型分析了我国农村医疗卫生投入效率的影响因素及其造成地区效率趋同的原因。结果发现,农村医疗卫生的投入规模对我国农村医疗卫生投入效率的影响显著,且只有该投入在规模上跨越单一门槛值、在结构上得以合理使用时,才能促使我国农村医疗卫生的投入效率在各地区间同步提高。
In this paper, we first use DEA method to measure the efficiency of rural medical and health care investment in our country from 1994 to 2007, and find that it is not only declining year by year, but also the differences among different regions are shrinking gradually. Based on this, we analyzed the factors that affect the efficiency of rural health care in China and the reasons for the convergence of regional efficiency through the establishment of panel data and its nonlinear threshold model. The results showed that the scale of rural medical and health care had a significant impact on the efficiency of rural medical and health care in our country, and only when the investment exceeded a single threshold in scale and was rationally used in structure, could the efficiency of rural medical and health care be promoted All regions simultaneously improve.
