数智时代，数字技术的普及推动了社会发展，也加深了网络、社交媒体与短视频等领域的数字成瘾问题。数字成瘾已成为兼具心理学、信息科学与社会治理意义的全球性挑战。文章基于系统性文献综述方法，综合近十年国内外相关研究，从个体心理机制、数字技术与算法特征以及社会制度与监管环境三个层面，梳理了数字成瘾的概念演化、多维成因与干预路径。研究发现，数字成瘾源于个体心理需求、算法推荐机制与制度环境的交互作用，进一步指出数字素养教育与图书馆社会服务在数字成瘾预防与干预中的潜在价值，并在此基础上归纳形成涵盖风险预警、行为引导与社会协同的综合治理框架。

In the era of digital intelligence, the widespread adoption of digital technologies has promoted social development while intensifying digital addiction in online environments such as social media and short-video platforms. Digital addiction has thus emerged as a global challenge with significant implications for psychology, information science, and social governance. Drawing on a systematic literature review, this paper synthesizes international and domestic research published over the past decade and examines the conceptual evolution, multidimensional antecedents, and intervention strategies of digital addiction from three perspectives: individual psychological mechanisms, digital technology and algorithm characteristics, and institutional and regulatory contexts. The review indicates that digital addiction arises from the interaction among psychological needs, algorithm-driven recommendation systems, and regulatory gaps. Furthermore, the study highlights the potential role of digital literacy education and library-based social services in the prevention and mitigation of digital addiction. On this basis, an integrated governance framework encompassing risk early warning, behavioral guidance, and social collaboration is proposed.
