Objective To evaluate the operation efficiency of clinical departments in hospitals and study its influencing factors.It provides reference for hospital decision makers to optimize the allocation of health resources.Methods DEA combi-ning with DRG indicator was used to comprehensively evaluate the input-output efficiency of study sample.Slacks Variable of DEA and Tobit regression were performed to identify improvement goals and influencing factors.Results 35％of clinical depart-ments health resource allocation were effective,and the pure technical efficiency and scale efficiency of 35％of clinical depart-ments were less than 1.The number of bed turnover had a positive effect on the operation efficiency of clinical departments and had statistical significance.Conclusion The clinical departments in the sample hospitals had a low level operating efficiency.DEA method combined with DRG index can better evaluate the operational efficiency of clinical departments.and assist hospital decision makers to adjust the allocation of health resources.According to the results of DEA,the hospital decision makers could adjusted the allocation of health resources,and combined with the influencing factors and actual needs to reinforce delicacy man-agement of clinical departments.
