医院经济效率的影响因素较多 ,有内部和外部因素 ,也有量化因素和非量化的政策因素。该文的目的在于从诸多因素中找出影响医院综合效率的主要因素、及其作用的方向和幅度。该文分别以单元成本、平均住院日和数据包络分析 (DEA)得分为因变量 ,以医院性质、级别、投入因素、政策因素等为自变量 ,应用多元线形模型和逐步回归模型分析方法 ,分析了医院内外因素的作用 ,结果显示 ,对淄博和南通两市讲 ,主要影响因素基本相同 ,医院级别越高效率相对越高 ,药品收入比例越高效率越低 ,医疗保障制度改革的实施有益于控制单元成本、提高DEA综合效率得分 There are many influencing factors of hospital economic efficiency, internal and external factors, as well as quantitative factors and non-quantitative policy factors. The purpose of this paper is to find out the main factors influencing the comprehensive efficiency of the hospital and the direction and extent of its effect from many factors. In this paper, the unit cost, average length of stay, and data envelopment analysis (DEA) scores were used as the dependent variables, and the hospital nature, level, input factors, and policy factors were used as independent variables. Multivariate linear models and stepwise regression model analysis methods were applied. The effect of internal and external factors in the hospital was analyzed. The results showed that the main influencing factors were basically the same for the cities of Zibo and Nantong. The higher the hospital level, the higher the efficiency, the higher the pharmaceutical income ratio, the lower the efficiency, and the implementation of the reform of the medical security system is beneficial. To control unit costs and improve DEA overall efficiency scores
