中介变量的拓展检验方法和应用研究

Research on the Test and Application of the Extended Method about Mediator

本文根据基本的中介变量检验方法,提出了运用回归分析的方法来检验较为复杂的中介模型的步骤,并讨论了完全中介作用模型、部分中介作用模型以及无中介作用模型的检验要求,同时运用一项实证研究中的数据对本文提出的检验程序和要求进行了详细的演示。最后,对人口统计学变量的处理方法进行了介绍并讨论了运用回归分析方法检验中介作用的缺陷。

Based on the testing method of the simple mediation model,this paper improves a method to test the complex mediation model using regression analysis. It also discusses the coefficient requirements and conditions of total-mediation model,partial mediation model and non-mediation model,and utilizes the data of an actual sample from a recent empirical study to show the process of how to test a complex model. At last,this paper introduces the method which deals with de-mographic data and discusses the limitation in using negression analysis to test the effect of mediation.
