本文利用地级市和二级医疗区的面板数据测算了医院的全要素生产率。该研究侧重于医疗领域和医院层面的规模经济。它使用平均住院时间作为衡量医疗质量的标准。我们使用来自医疗领域的数据而不是来自医院水平的数据来避免病例组合偏倚。我们控制不可观察的区域特征，采用面板数据估计。我们通过使用数量数据消除了地区之间的价格差异。我们的研究结果表明，医院规模影响生产率：医院越大，生产率越高。医院规模效应在经济上具有重要意义：当医院规模扩大一倍时，医院的生产率将提高10%以上。当我们不控制平均停留时间时，规模效应为零。主要的政策含义是一个明确的事实，即合并医院可以提高生产力。
This paper estimates the total factor productivity (TFP) of hospitals by using panel data drawn from prefectures and secondary medical areas. The study focuses on the economies of scale at the medical area and hospital levels. It uses the average length of stay as a measure of medical quality. We avoid case-mix bias by using data from medical areas instead of those from the hospital level. We control unobservable regional characteristics by employing panel data estimation. We eliminate price disparities among regions by using quantity data. Our results show that hospital size affects productivity: the larger the hospital, the higher the productivity. The hospital-size effect is economically significant: hospital productivity increases by more than 10% when the size of the hospital doubles. The size effects are null when we do not control the average length of stay. The main policy implication is the clear fact that consolidating hospitals improves productivity.
