摘要比较了医院效率测量常用统计方法的相关性和使用范围,利用经过主成分分析方法降维处理过的医院实际数据,对比率分析、随机前沿分析和数据包络分析的结果进行相关性分析.认为比率分析能便捷地展示医院效率顺序,随机前沿分析的前提假设更为苛刻但结果更稳定,而数据包络分析的相对优势更为明显,更适合处理多投入-多产出的医院效率测量问题.

abstractsA comparison was made for the correlation and application scope of the statistical methods commonly used by hospitals for their efficiency measurement.Hospital data processed with PCA (principal component analysis)for dimension reduction were used in a correlation analysis for the results of ratio analysis (RA),stochastic frontier analysis(SFA)and data envelopment analysis(DEA).The authors hold that the RA can expediently display the order of hospital efficiency,the SFA demands a stricter premise yet presents more stable results,while the DEA boasts greater relative advantages and thus suitable for processing hospital efficiency measurement tasks of multi-input and multi-output indexes.
