| 摘要: |
| 目的对军队医院范围经济进行测定。方法收集3个地区57家军队医院2005~2007年的面板数据,建立基于面板数据的混合回归模型和时点固定效应模型,根据假设检验结果,择优选择成本函数模型,并依据范围经济概念,建立范围经济模型。应用计量经济学方法估计参数,计算医院范围经济。结果两模型假设检验结果认为,混合回归模型优于时点固定效应模型。本次测定的军队医院全部具有范围经济,医院规模越大,级别越高,范围经济性越显著。结论大规模的医院开发高度相关主营业务可实现更大的范围经济性。 |

| Abstract: |
| ObjectiveTo measure the economies of scope of military hospitals in China.MethodsWe collected the panel data of 2005 to 2007 from 57 military hospitals, based on which we constructed the pooled regression model and time fixed effect regression model.The best cost function model was selected according to the result of hypothesis testing, and the model of economies of scope was constructed according to the conception of economies of scope.Then the parameters were estimated by econometric methods, and the coefficient estimates were used to calculate the economies of scope of hospitals of each category.ResultsThe hypothesis testing results of the two models showed that the pooled regression model was superior to the time fixed effect model.All the military hospitals included in the present study showed economies of scope; the larger and higher level the hospitals, the stronger economies of scope was.ConclusionLarge-scale hospitals can achieve better economies of scope by developing highly relevant main bussiness. |
