社会信任是国家和社会稳定的重要基石,中国正处于新时代背景下,因此,公民社会信任尤为重要。相关研究表明,社会信任与社会排斥、社会情绪和社会治理感知有关。本研究旨在探讨工薪阶层社会情绪和社会治理感知对社会排斥与社会信任的序列多重中介效应。本研究使用中国家庭追踪调查2020年的数据(N = 8112)进行分析。研究结果表明,工薪阶层受到的社会排斥越严重,其社会信任水平越低;不同领域社会排斥对工薪阶层社会信任的影响存在差异,其中社会关系排斥对社会信任影响最大;工薪阶层社会排斥对人际信任的负面影响远大于对政府信任的影响;社会情绪和社会治理感知在社会排斥和社会信任的关系中具有多重中介效应。以上研究结果揭示了社会排斥与社会信任之间的内在机制,对于国家和政府改善工薪阶层社会支持现状,提升社会信任水平,构建和完善社会主义和谐社会具有重要意义。Social trust is an important cornerstone of national and social stability.
