本文对中国区域医院效率进行了调查。由于医院手术数量自然增加，患者死亡率的不良输出可能引发医疗纠纷和诉讼，本研究采用数据包络分析对考虑和不考虑不良输出的效率评分进行评价和比较。基于2002-2008年省级面板数据，并考虑风险调整后的不良产出，实证估计表明医院效率处于中等水平，但从0.6881逐渐上升到0.8159。重要的是，在不考虑不良产出的情况下，平均效率得分被高估了，各省之间的效率排名变化很大。沿海地区与非沿海地区之间存在效率差距，但这一差距的缩小主要得益于西部地区效率的快速提升。然而，中部地区的效率得分仍然明显低于东部和西部地区。此外，新型农村合作医疗制度的启动总体上提高了中国的医院效率，特别是对于非沿海地区。运筹学学报（2012）63,715-725。doi:10.1057/jors.2011.77 2011年9月14日发布
This paper investigates regional hospital efficiency in China. As hospital operations naturally increase along with an undesirable output of patient mortality, which may induce medical disputes and ligations, this study adopts data envelopment analysis to evaluate and compare the efficiency scores obtained with and without considering the undesirable output. On the basis of province-level panel data over 2002-2008 and considering the risk-adjusted undesirable output, empirical estimates indicate that hospital efficiency is moderate, but increases gradually from 0.6881 to 0.8159. Importantly, without considering the undesirable output, the average efficiency score is overestimated and the efficiency ranking across provinces changes considerably. An efficiency gap is found between coastal and non-coastal regions, but this gap's drop is mainly contributed by the fast efficiency improvement of the western regions. However, the central regions continue to achieve a significantly lower efficiency score than the eastern and western regions. Moreover, the initiation of the New Rural Cooperative Medical System has overall enhanced hospital efficiency in China, especially for the non-coastal regions.
