随着短视频平台、社交媒体和即时通信工具的普及，汉语网络语言不断演化，其中以语音简化、谐音替代和缩略表达为主要特征的网络语音变异现象现象日益普遍，如“酱紫”“不造”“表”“蓝瘦香菇”等表达广泛活跃于网络交际之中。这类语言现象既体现了语言经济原则对语言形式演变的影响，也反映出数字媒介环境下汉语表达方式的创新。然而，对于国际中文学习者而言，网络语音变异现象突破了现代汉语规范表达，在语音、词汇和语体等方面容易造成理解与使用偏误，给国际中文教学带来新的挑战。本文以语言经济原则为理论基础，结合网络语言实例，分析汉语网络语音变异现象的形成机制，探讨其对国际中文教育的影响，并提出培养语体意识、强化辨析能力、合理利用真实网络语料等教学策略。研究认为，国际中文教育应坚持规范语言教学与真实语言输入并重，在帮助学习者掌握现代汉语规范表达的基础上，引导其正确理解和辨析网络语言，从而提升跨文化交际能力和真实语境中的汉语应用能力。

With the popularization of short-video platforms, social media and instant messaging tools, Chinese internet language has kept evolving. Among it, internet phonetic variations featured by phonetic simplification, homophonic substitution and abbreviated expressions have become increasingly prevalent. Typical examples such as jiangzi, buzao, biao and lanshou xianggu are widely used in online communication. Such linguistic phenomena not only reflect the influence of the Principle of Linguistic Economy on the evolution of linguistic forms, but also embody innovations in Chinese expressive patterns under digital media environments. Nevertheless, for international Chinese learners, internet phonetic variations deviate from standard modern Chinese norms and tend to trigger comprehension and application errors in pronunciation, vocabulary and stylistics, posing new challenges to international Chinese language teaching. Based on the Principle of Linguistic Economy, this paper analyzes the formation mechanism of Chinese internet phonetic variations with authentic internet language cases, discusses their impacts on international Chinese language education, and proposes teaching strategies including cultivating learners’ stylistic awareness, strengthening their discrimination ability and rationally adopting real online linguistic materials. The study argues that international Chinese language education should balance standardized language instruction and authentic language input. On the premise of helping learners master standard modern Chinese, teachers are supposed to guide students to properly understand and distinguish internet language, so as to improve their cross-cultural communication competence and Chinese practical ability in real-life contexts.
