本研究分析了通径分析方法存在的三项缺点:主观性、反复性和不确定性。并根据实际资料,针对这些问题,设法克服。借助岭估计、主成份估计方法层层分析了指标,构造了通径图,使构造的通径图较客观、稳定、合理。最后,对构造的通径图进行了通径分析,得出了原因指标对结果指标的直接作用、间接作用及剩余作用的大小,为医院管理工作提供了数量依据。 This study analyzes three shortcomings of path analysis methods: subjectivity, repeatability, and uncertainty. According to actual data, these problems are overcome. Using ridge estimation and principal component estimation methods, the indicators were analyzed in layers, and path diagrams were constructed to make the path diagrams of the structures more objective, stable, and reasonable. In the end, the path diagram of the structure is analyzed, and the direct and indirect effects of the cause index on the result index and the magnitude of the residual effect are obtained, which provides a quantitative basis for hospital management.
