文章分别运用三阶段数据包络分析(data envelopment analysis，DEA)模型和Malmquist指数对2016—2020年安徽省医疗卫生支出的静态和动态效率值进行了测算与分析。研究表明，不考虑环境因素和随机干扰项的影响，安徽省医疗卫生支出效率整体偏低；外部环境因素显著影响安徽省医疗卫生支出效率，人口密度和城镇化率为正向影响，人均国内生产总值、医疗卫生支出占比和财政分权为负向影响；剔除外部环境及随机噪声等影响因素后，安徽省医疗卫生支出效率明显提升，纯技术效率的上升是综合技术效率提高的关键；Malmquist指数测算结果显示，安徽省医疗卫生支出存在规模经济效应，且主要受技术进步的制约，“十三五”期间全省医疗卫生支出效率总体呈下降趋势。
The article measured and analyzed the static and dynamic efficiency values of medical and health expenditure in Anhui Province from 2016 to 2020 using the three ? stage DEA model and Malmquist index，respectively. The study showed that，the overall efficiency of health care expenditure in Anhui Province was low regardless the influence of environmental factors and random disturbance terms. External environmental factors significantly affected the efficiency of medical and health expenditure in Anhui Province，with population density and urbanization rate showing positive effects，while GDP per capita，medical and health expenditure ratio and fiscal decentralization having negative effects. After excluding the influence of external environmental and random noise factors，the efficiency of medical and health expenditure in Anhui Province has improved significantly，while the increase of pure technical efficiency was the key factor to the improvement of comprehensive technical efficiency. The results of Malmquist index showed that there was a scaled economic effect on medical and health expenditure in Anhui Province，which was mainly constrained by technological progress. The efficiency of medical and health expenditure in the province was generally decreasing during the 13th Five?Year Plan period.
