互联网数字时代背景下，网络语言的发展更具动态性与创造性。文章从社会语言学的“语言与社会互融”视角出发，聚焦网络语言中的“系统性错别字”现象，通过数据分析与文献梳理，对其分类体系进行考察，并结合模因论与语言经济学理论，深入探究此类“错误形式”在网络社会中的生成与传播动因，阐释其何以具备持续的生命力。研究发现，网络“系统性错别字”主要可分为效率与避险驱动型、情感与风格表达型及身份标识型三类，体现了当代青年群体在数字语境下为满足深层心理与社会需求而进行的主动语言实践。然而，面对网络语言质量参差不齐的现状，尤其考虑到青少年群体价值观尚未完全形成，平台、社会等相关方应加强对其创造与使用的引导与监管，共同营造一个兼具创造性与规范性的健康网络语言环境。

In the context of the digital Internet era, the development of online language has become increasingly dynamic and creative. From the perspective of "language-society integration" in sociolinguistics, this paper focuses on the phenomenon of "systematic misspelling" in online language. Through data analysis and literature review, it examines the classification system of this phenomenon. Drawing upon memetics and language economics, the study delves into the generative and communicative motivations behind such "erroneous forms" in cyberspace, and elucidates why they possess sustained vitality. The findings reveal that online "systematic misspellings" can be categorized into three main types: efficiency and risk-avoidance driven, emotion and style expressive, and identity-marking. These categories reflect the active linguistic practices of contemporary youth groups in digital contexts, aimed at satisfying deep-seated psychological and social needs. However, given the uneven quality of online language and the fact that adolescents' value systems are not yet fully formed, it is imperative for platforms, society, and other relevant stakeholders to strengthen guidance and regulation regarding the creation and use of such expressions, thereby fostering a healthy online linguistic environment that balances creativity with normativity.
