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.
