| 摘 要： | 目的研究上海市公立医院整合对规模经济的影响。方法收集上海市67家医院从1999~2004年的数据,共401个样本,通过中位数回归模拟多产出成本函数,并计算医院整合前后的出院患者边际成本和规模经济。结果变量床位数、人力成本支出、门急诊人次、出院人数、医院区域、级别,以及2003、2004年的虚拟变量对医院成本均有显著性影响。结论无论是三级医院还是二级医院在整合前后均存在规模经济;纵向整合增加了被整合二级医院的患者收治数量,改善了被整合医院的运营状况,一定程度上实现了患者的分流。

| Abstract: | Objective To study the effect of public hospitals vertical integration on scale economy in Shanghai. MethodsA total of 401 samples of 67 hospitals from 1999 to 2004 in Shanghai were collected.Median regression was performed to estimate the multi-output cost function and marginal cost of discharge patients,and scale economies were calculated.Results The independent variables Beds,W,X1,X23,Region,Level,Y03,and Y04 were all predictors of cost.Conclusion Both integrated tertiary and secondary hospitals had scale economy before and after integration.Integration enhanced the output and improved the efficiency of integrated secondary hospitals.To some extent,patients were dispersed to secondary hospitals. |
