【摘要】 本文基于自建历时平衡语料库，采用跨学科对比视角，系统考察学术汉语中自我提及语在近三十年间（1994—2024）的演变轨迹与动因。研究发现：总体上，自我提及语的使用呈现先升后降的倒U型演变趋势，反映出学术话语规范化进程的复杂动态。跨学科共性层面，两大学科中人称代词的使用频率均显著下降，体现了学术写作去主观化的普遍趋势。学科差异层面，在语言学领域，机构自称名词系统性缺位，作者自称名词与抽象主体名词增长；物理学领域，作者自称名词锐减，机构自称名词出现，抽象主体名词稳步上升。研究表明，汉语学术话语的自我指涉模式正经历从研究者中心到知识实体中心的范式转型，其本质是学科认知逻辑与社会文化因素协同驱动的修辞重构过程。值得注意的是，本研究揭示的制度化转向（即知识实体化）与2025年新国标GB/T6447—2025《文献摘要编写规则》对第一人称使用的包容性规定之间，构成鲜明的制度性张力，折射出学科修辞传统与国家规范体系间的动态调适需求。这一发现为构建学科适配的指称规范提供了重要的历时证据，对学术话语的规范化建设具有启示意义。更多还原

【Abstract】 Based on a self-built diachronic balanced corpus and adopting an interdisciplinary comparative perspective, this study systematically examines the evolutionary trajectory and driving forces of self-mention expressions in academic Chinese discourse over the past three decades(1994-2024). The findings reveal that, overall, the use of self-mention expressions follows an inverted U-shaped evolution pattern, initially increasing and then decreasing, reflecting the complex dynamics of the standardization process in academic discourse. At the level of crossdisciplinary commonalities, the frequency of personal pronouns significantly declined in both major disciplines, indicating a universal trend toward de-subjectification in academic writing. At the level of disciplinary differences, in the field of linguistics, institutional self-referential nouns are systematically absent, while the use of authorial self-reference nouns and abstract subject nouns increased. In contrast, in the field of physics, authorial self-reference nouns sharply decline,institutional self-referential nouns emerge, and abstract subject nouns steadily rise. The research demonstrates that the self-referential patterns in Chinese academic discourse are undergoing a paradigm shift from researcher-centeredness to knowledge-entity-centeredness, which is essentially a process of rhetorical reconstruction driven by the synergistic effects of disciplinary cognitive logic and socio-cultural factors. It is worth noting that the institutionalizing shift revealed in this study,namely knowledge-entity formation, stands in clear institutional tension with the inclusive provisions on first-person usage in the new national standard GB/T6447-2025, Rules for Writing Abstracts, reflecting the need for dynamic adjustment between disciplinary rhetorical traditions and national normative systems. This discovery provides crucial diachronic evidence for constructing discipline-sensitive referential norms and holds significant implications for the standardization of academic discourse.更多还原
