基于数据包络分析的县级综合医院规模经济效率研究

Study on Economical Efficiency of Scale in County General Hospitals Based on Data Envelopment Analysis

目的:从医院运营效率角度求证县级综合医院医院规模经济现象,如果存在则初步确定医院床位适宜规模。方法:应用数据包络分析方法分析不同床位分组医院效率得分及其规模报酬状态,检验不同规模医院效率得分、规模报酬状态是否具有显著性差异,同时对非数据包络分析有效决策单元进行投入产出投影分析。结果:(1)不同规模医院组效率得分具有显著性差异;(2)不同规模医院组规模经济状态与床位分组明显相关;(3)医院床位和人员存在较大过剩,特别是大规模医院组过剩比例高达22.7%。结论:县级综合医院存在规模经济效率现象,规模整体过剩,床位适宜规模在250～300张之间。

Objective： To clarify the existence of economies of scale in efficiency in county general hospitals and determine the optimal scale of hospital＇s bed. Methods： Data envelopment analysis was used to measure the efficiency and the status of return to scale（RTS）, and then the analysis of variance was used to test the significance difference among different groups. Results： （1）The diffe- rence of efficiency scores among hospital groups are great; （2）the status of RTS of different hospital groups was significantly related to bed grouping; （3） there is great surplus in hospital beds and personnel, especially in large hospital group as high as 22.7%. Conclusion： There exists the economical efficiency of scale in county general hospitals. The overall size of hospital bed is redundant and the optimal size is in the range of 250-300.
