随着短视频与社交媒体发展，废话文学成为影响力突出的网络语言现象，但现有研究对其语言本体与交际功能挖掘不足。本文以语言哲学为框架，整合维特根斯坦语言游戏说、奥斯汀言语行为理论与格赖斯合作原则，采用文献研究、语料库分析与理论分析法，探究废话文学的无效表征与有效性机制。研究发现，废话文学多表现为同义反复、表达模糊，内容消解深度、回避实质信息，偏离常规语言规范，表层不承载实用命题信息；但在交际中可实现调侃、情绪缓冲等语用功能。本文以此印证“意义即使用”在网络语境的实践形态，拓展汉语语义研究维度，为网络语言规范治理提供参考。

With the development of short videos and social media, banal literature has become a prominent online language phenomenon. However, existing studies have insufficiently explored its language essence and communicative functions. This paper, based on the framework of language philosophy, integrates Wittgenstein's theory of language games, Austin's theory of speech acts, and Grice's cooperative principle, and employs literature research, corpus analysis, and theoretical analysis methods to explore the ineffective representation and effectiveness mechanism of banal literature. The study finds that banal literature often manifests as repetitive synonyms, ambiguous expressions, deep content disintegration, avoidance of substantive information, deviation from conventional language norms, and lack of practical propositional information on the surface; however, it can achieve pragmatic functions such as teasing and emotional buffering in communication. This paper thereby confirms the practical form of "meaning as use" in the online context, expands the dimension of Chinese semantic research, and provides a reference for the governance of online language norms.
