Hospital diversification and its impact on the operating ratio are studied for 168 hospitals during the period from 1999 to 2004. Diversification and the operating ratio are modeled in a two-stage least squares (TSLS) framework as being jointly dependent. Institutional diversification is found to yield a better financial position, and the better operating ratio allows the institution the wherewithal to diversify. The impact of external government planning and hospital competition are also measured. An institution lifecycle hypothesis is advanced to explain hospital behavior: boom and bust, diversification and divestiture, occasionally leading to closure or merger. Management's attitude concerning risk and reward is considered.
对1999年至2004年期间168家医院的多元化及其对运营比率的影响进行了研究。在两阶段最小二乘法（TSLS）框架中，将多元化和运营比率建模为共同依赖的变量。研究发现，机构多元化会带来更好的财务状况，而更好的运营比率使机构有能力实现多元化。同时还衡量了外部政府规划和医院竞争的影响。提出了一个机构生命周期假说，以解释医院的行为：兴衰、多元化和撤资，偶尔会导致关闭或合并。研究还考虑了管理层对风险和回报的态度。
