摘要
管理研究通常根据统计显著性判断调节效应是否存在,然而统计显著性并不等同于管理者所探求的实践意义,即实际显著性。鉴于此:首先,区分了调节效应的统计显著性和实际显著性的差异;其次,运用文献计量法对2011~2023年间发表在《管理世界》《南开管理评论》《心理学报》和《管理学报》上采用调节效应检验的研究进行梳理,结果表明对调节效应进行实际显著性检验仍然需要推广。在此基础上,提出检验调节效应实际显著性的两种检验方法:效应量差值ΔR^(2)和因变量预测值差异。最后,使用已发表研究的真实数据对实际显著性检验方法进行了实例分析。
Nowadays,management researchers commonly rely on statistical significance when testing the moderation effects.However,statistical significance is not equivalent to practical significance.This study has four purposes.First,this study described the difference between the statistical significance and the practical significance of the moderation effect.Second,this study applied the method of bibliometrics to analyze the published studies between 2011 and 2023 with reported moderation effects in four top-tier management journals in China,i.e.,Journal of management world,Nankai Management Review,Acta Psychologica Sinica and Chinese Journal of Management.The results show that Chinese management researchers have paid more attention to the practical significance of the moderation effect,but the magnitude of the practical significance reported was not substantial.Third,we further introduced two analytical strategies for evaluating the practical significance of moderation effects:Deviation R-square(ΔR^(2))and the absolute discrepancies between the dependent variable’s predicted values from two regression models.Finally,this study illustrated the two analytical strategies for testing the practical significance of the moderation effects using the raw data of a recently published study.
