There is a growing interest in the cross-country comparisons of the performance of national health care systems. The present work provides a comparison of the technical efficiency of the hospital sector using unbalanced panel data from OECD countries over the period 2000-2009. The estimation of the technical efficiency of the hospital sector is performed using nonparametric data envelopment analysis (DEA) and parametric stochastic frontier analysis (SFA). Internal and external validity of findings is assessed by estimating the Spearman rank correlations between the results obtained in different model specifications. The panel-data analyses using two-step DEA and one-stage SFA show that countries, which have higher health care expenditure per capita, tend to have a more technically efficient hospital sector. Whether the expenditure is financed through private or public sources is not related to the technical efficiency of the hospital sector. On the other hand, the hospital sector in countries with higher income inequality and longer average hospital length of stay is less technically efficient.
人们对比较不同国家医疗保健系统的绩效越来越感兴趣。本研究利用经合组织国家 2000-2009 年的非平衡面板数据，采用非参数数据包络分析（DEA）和参数随机前沿分析（SFA）对医院部门的技术效率进行了比较。通过对不同模型规格中得出的结果进行斯皮尔曼等级相关分析，评估了研究结果的内部和外部有效性。使用两步 DEA 和单阶段 SFA 的面板数据分析表明，人均医疗保健支出较高的国家往往具有更具技术效率的医院部门。支出是通过私人还是公共来源融资与医院部门的技术效率无关。另一方面，收入不平等程度较高和平均住院时间较长的国家的医院部门技术效率较低。
