The loss of followers poses a severe threat to the development of microblogging platforms and bloggers. However, the reasons behind users’ unfollowing behavior remain unclear. Drawing on the person-environment fit framework, we examined how different types of person-environment misfits affect users’ unfollowing intention and the relationship between these misfits. We collected the data to test the research model from 305 Weibo users via an online survey. The results suggest that from the perspective of complementary misfit, information overload increases social media fatigue, and information irrelevance increases followers’ expectation disconfirmation. From the perspective of supplementary misfit, perceived value dissimilarity positively affects followers’ fatigue and disconfirmation. These negative psychological states consequently lead to followers’ unfollowing intention. Furthermore, our results revealed the positive effects of perceived value dissimilarity on information overload and information irrelevance. We also discuss the theoretical contributions and practical implications of this study.

追随者的流失对微博平台和博主的发展构成严重威胁。然而，用户不关注行为背后的原因仍不清楚。借鉴人与环境契合框架，我们研究了不同类型的人与环境不匹配如何影响用户的不跟随意图以及这些不匹配之间的关系。我们通过在线调查收集了来自 305 位微博用户的数据来测试研究模型。结果表明，从互补错配的角度来看，信息超载会增加社交媒体疲劳，信息不相关会增加追随者的期望失准。从补充错配的角度来看，感知价值差异正向影响追随者的疲劳和不确定性。这些消极的心理状态因此导致追随者的不追随意图。此外，我们的结果揭示了感知价值差异对信息过载和信息不相关的积极影响。我们还讨论了这项研究的理论贡献和实际意义。
