Hospital investment behavior is commonly explained by means of either supply or demand factors. The inherent limitations of these models have led to ambiguous conclusions. This study applies a different approach, whereby investment generation is explained by means of a stock adjustment model. The model is empirically tested on a sample of New York City hospitals. Relative investment is found to be directly related to occupancy rate, indicating rationality in the hospital investment process. Scalar factors are also shown to be significant, implying the concept of preferred hospital size.
医院投资行为通常通过供给或需求因素来解释。这些模型固有的局限性导致了模棱两可的结论。本研究采用了一种不同的方法，即通过存量调整模型来解释投资生成。该模型在纽约市医院样本上进行了实证检验。研究发现相对投资与入住率直接相关，这表明医院投资过程具有合理性。标量因素也被证明具有显著性，这意味着存在优选医院规模的概念。
