We analyze hospital efficiency and productivity growth using an innovative approach which employs the directional distance function and the Luenberger productivity indicator. The primary advantage of our approach is that both input contractions and output expansions are considered. Our model generates a productivity indicator that is decomposed into the usual constituents of productivity growth: technological change and efficiency change. For the sake of comparison, we also use the Malmquist productivity index. The empirical results based on a sample of Portuguese hospitals from 1997 to 2004 show that, on average, those hospitals experienced very weak productivity growth over that period. In addition, the incidence of technological change was remarkably low.
我们使用一种创新方法来分析医院效率和生产率增长，该方法采用了方向距离函数和卢恩伯格生产率指标。我们方法的主要优点在于同时考虑了投入缩减和产出扩张。我们的模型生成了一个生产率指标，该指标可分解为生产率增长的常见构成部分：技术变革和效率变革。为了进行比较，我们还使用了马尔姆quist生产率指数。基于1997年至2004年葡萄牙医院样本的实证结果表明，在此期间，这些医院的生产率增长总体非常微弱。此外，技术变革的发生率极低。
