浙江省各地区医疗机构DEA—Malmquist效率指数分析

Analysis on DEA-Malmquist efficiency index of medical facilities in Zhejiang province

目的测算浙江省医疗机构生产率的变化状况，为提高医疗机构运营效率提供决策依据和参考。方法收集浙江省医疗机构2005年至2010年6年面板数据（4项投入指标，5项产出指标），应用数据包络分析（DEA）的Malmquist模型进行分析。结果5年间浙江省医疗机构生产率的年平均增长率为2．0％，进一步分解发现：技术进步年均增长率为1．8％，技术效率、纯技术效率增长率均为0．2％，而规模效率没有变化。结论浙江省医疗机构生产率增长较为缓慢，其增长贡献主要来源于技术进步，并且存在技术衰退迹象；为最大限度提高医疗机构生产率，在引进技术创新投入的同时，更应加强医疗机构管理与配置，激发技术效率和规模效率。

Objective To measure the changes of total factor productivity （TFP）of Zhejiang medical facilities for decision makers to promote their service efficiency. Methods Collecting the panel data of 2005-2010（four input indexes and five output indexes）from medical facilities in Zhejiang province and measuring with Malmquist index of DEA programs of DEAP2.1. Results The average annual TFP growth rate in the period is 2. 0 %. A further decomposition found that the average annual growth rate of technology progress is 1.8 %, while that of technical efficiency and pure technical efficiency is only 0. 2 % respectively. In the meantime, no scale efficiency growth was found. Conclusion The average annual growth of total factor productivity of Zhejiang medical institutions is substantially low in the period, with technology recession found as well. To maximize productivity of the medical sector, the allocation and internal management should be strengthened to stimulate technical efficiency and scale efficiency while encouraging technology innovation.
