算法赋能下的媒介实践：银发族短视频平台使用行为对社会孤立的影响

Media Practices under Algorithmic Empowerment: The Impact of Short-Video Platform Usage Behaviors of Silver-Haired Generation on Social Isolation

摘要: 随着数字适老化政策的推进，银发族加速跨越“数字鸿沟”，短视频平台已成为老年群体重要的信息获取与娱乐消遣渠道。然而，在技术赋能的美好叙事之外，越来越多的老年人出现高强度使用、时间沉浸与行为失控现象。本研究聚焦于短视频平台场景下银发族的高强度使用与社会孤立问题，基于社交媒体平台的公开帖文、评论及相关新闻报道的文本分析，揭示其多维表征、技术机制与恶性循环逻辑。研究发现，银发族的高强度使用表现为时间沉浸、行为异化与信任错位三重相互强化的特征。在理论层面，本研究探讨了现有成瘾理论与信息茧房理论在老年群体中的适用性与局限。研究建议从家庭沟通、平台防沉迷设计、算法监管与社会支持网络构建等层面协同干预。

Abstract: With the advancement of digital age-friendly policies, the silver-haired generation is rapidly crossing the “digital divide”. Short video platforms have become important channels for information acquisition and entertainment for the elderly population. However, beyond the positive narrative of technological empowerment, a growing number of older adults are exhibiting high-intensity usage, time immersion, and behavioral dyscontrol. This study focuses on the phenomenon of high-intensity use and social isolation among the silver-haired generation in the context of short video platforms. Based on a textual analysis of public posts and comments on social media platforms (such as Weibo, Douban, Xiaohongshu, and Zhihu) and related news reports, it reveals the multi-dimensional manifestations, technological mechanisms, and vicious cycle of this phenomenon. The study finds that high-intensity use among the silver-haired generation is characterized by three mutually reinforcing features: time immersion, behavioral alienation, and trust misalignment. Theoretically, this study examines the applicability and limitations of existing addiction theories and information cocoon theory in the elderly population. The study suggests collaborative interventions at the levels of family communication, platform anti-addiction design, algorithmic regulation, and the construction of social support networks.
