摘　　要：偶然新闻接触成为替代性新闻获取方式,其对公众政治参与有何种影响,尚未得出一致结论,尤其缺乏基于中国本土的经验研究。本文通过1600名中国网民的调查数据,基于政治心理理论,分析政治知识在社交媒体偶然新闻接触与政治参与之间的作用机制。研究发现,社交媒体偶然新闻接触对线上和线下政治参与有正向预测作用。事实政治知识在社交媒体偶然新闻接触与线下政治参与之间发挥负向中介作用;感知政治知识在社交媒体偶然新闻接触与线上和线下政治参与之间发挥正向中介作用。Incidental news exposure has emerged as an alternative method for accessing news,but its impact on public political participation remains unclear,particularly in the context of China where empirical research is scarce.This paper uses survey data from 1,600 Chinese netizens to explore the relationship between incidental news exposure on social media and political participation,drawing on political psychology theory.The study finds that incidental news exposure on social media positively predicts both online and offline political participation.Moreover,factual political knowledge negatively mediates the relationship between incidental news exposure and offline political participation,while perceived political knowledge positively mediates this relationship for both online and offline political participation.
