Abstract： Based on the dual perspective of cognitive pathway and transparency , this research conducts a meta-analysis of 108 empirical results from 40 nudge studies published in Behavioral Public Policy(2017~2022) and Behavioral Science & Policy(2015~2022). This research systematically evaluates the effectiveness of nudging interventions, compares advantages of nudging measures in terms of different cognitive pathways and transparency, explores the influencing factors of heterogeneity in nudging effects, and analyzes the interactive effects of cognitive pathways, transparency, and influencing factors on nudging effectiveness. Our analysis reveals that:（1）The comprehensive effect of nudging intervention is relatively small, and the effect of nudging tools in different studies shows significant differences;（2）There are differences in nudging effectiveness between different cognitive pathways and transparency, and there is an interactive effect between cognitive pathway and transparency on nudging effectiveness;（3）The effectiveness of nudge is influenced by research designs and behavioral domains. The cognitive pathways through which nudge works, the transparency of nudge design, and influencing factors of heterogeneity have complex interactive effects on nudging effectiveness.
