Using yearly panel data from 2011 to 2017 on New Zealand District Health Boards (DHBs), this study combines principal component analysis and data envelopment intertemporal analysis with the double-bootstrap approach to estimate the technical efficiency of health care providers along with the trend of efficiency performances. The results show that although most large DHBs have improved their level of technical efficiency between 2011 and 2017, the majority of medium- and small-sized DHBs have not seen any noticeable improvement in their level of technical efficiency. The results also show that large and tertiary DHBs operate at a high level of technical efficiency. In contrast, most of the medium- and small-sized DHBs posted some of the lowest technical efficiency scores. Furthermore, the results show that medium- and small-sized DHBs have a higher average length of hospital stays which is found to be associated with decreasing levels of technical efficiency scores.
本研究利用新西兰地区卫生局（DHBs）2011 年至 2017 年的年度面板数据，采用主成分分析和数据包络分析时空分析，并结合双重引导方法，估算了医疗服务提供者的技术效率及其效率表现的趋势。结果表明，尽管大多数大型 DHBs 在 2011 年至 2017 年间提高了技术效率水平，但大多数中型和小型 DHBs 的技术效率水平没有明显提高。结果还表明，大型和三级 DHBs 的技术效率水平较高。相比之下，大多数中型和小型 DHBs 的技术效率得分较低。此外，结果表明，中型和小型 DHBs 的平均住院时间较长，这与技术效率得分的下降有关。
