在社会语言学视域下，徐则臣的小说创作展现出对“语言生活”的多维书写与深刻思考。微观层面，小说通过“知觉书写”将方言升华为承载乡愁、确证存在与协商身份的审美符号与权力工具，揭示个体深层的语言身份焦虑。中观层面，以京杭大运河为核心的叙事空间建构了贯通古今、连接本土与世界的“超语场”，呈现语言的社会分层、翻译伦理、历时传承与多语景观的复杂互动。宏观层面，“语言作为方法”的美学建构尤为突出，体现为“雅正为本”的风格自觉、语言从“工具”升华为“信物”与“路径”的功能认知，以及“实证调查”与“知识互文”的方法论支撑。三者共同作用，使语言生活的审美再现升华为一种具有范式意义的文学实践。徐则臣的创作不仅记录了近现代中国的语言变迁，更在学科交叉层面回应了文学与语言学的3个核心问题：文学文本作为语言生活研究材料的价值、虚构叙事对实证研究的超越，以及两个学科深度互文并共同构建语言生活图景的可能。

Viewed through a sociolinguistic lens, Xu Zechen’s fiction presents a multi-dimensional portrayal of and profound reflection on “language life”. At the micro level, his perceptual writing transforms a dialect into an aesthetic symbol and an instrument of power that conveys nostalgia, confirms individual existence, and negotiates identity, thereby revealing the deep linguistic identity anxieties of the individual. At the meso level, the Grand Canal-centered narrative space constructs a trans-lingual field integrating ancient and modern times as well as local and global contexts, demonstrating the complex interactions among the social stratification of language, translation ethics, diachronic transmission and multilingual landscapes. At the macro level, his aesthetic construction of “language as method” is particularly prominent, manifested as stylistic awareness based on elegance and propriety, the recognition that language has evolved from a practical tool into a “token of trust” and a “pathway”, as well as methodological support from empirical investigation and knowledge-based intertextuality. Altogether, the three dimensions elevate the aesthetic representation of language life into a paradigmatic literary practice. Xu Zechen’s works not only record the linguistic changes in modern and contemporary China, but also address three core issues at the intersection of literature and linguistics: the value of literary texts as research materials for language life, how fictional narratives transcend empirical research, and the possibility of in-depth interdisciplinary integration to jointly construct the panorama of language life.
