| 摘 要： | 中介分析主要用于探究自变量X与因变量Y之间的因果关系机制，将自变量X与因变量Y之间的因果路径进行分解，判断中介变量M是否在其因果路径中起作用及其作用大小。经典的中介分析方法一般仅针对单一中介变量。本文介绍了一种新的针对多个中介变量的中介分析方法。

| Abstract: | Mediation analysis is mainly used to explore the causal mechanism between independent variable X and dependent variable Y. It determines whether mediator M plays a role and evaluate the role''s degree in the causal path by decomposing the causal path between the independent variable X and the dependent variable Y. However, the classical mediation analysis is generally used for single mediator. This paper introduces a new mediation analysis method for multiple mediators. |
