引言和结语中言据性对英汉学术语篇作者身份建构的影响

The Influence of the Evidentiality in the Introduction and Conclusion on the Author Identity Construction in English and Chinese Academic Discourse

摘要: 言据性作为标示信息来源及认知态度的语言资源，在学术语篇的作者身份建构中发挥着重要作用。本研究基于自建3万词的英汉语言学学术论文语料库，采用廖巧云与翁馨(2022)的言据性分类框架，结合定量与定性方法，考察引言与结语中言据性资源对作者身份建构的影响。研究发现：(1) 引言中，英文论文多用感官型据素和信念型据素，建构实证观察者与立场宣告者身份；中文论文多用转述据素，呈现文献综述者身份。(2) 结语中，英文论文大量使用信念型据素和感官型据素，建构自信的理论贡献者身份；中文论文据素使用显著减少，作者身份趋于隐退。(3) 英语文化鼓励结语中彰显个人贡献，汉语文化偏好谦逊含蓄的结语风格。本研究揭示了据素选择与学术文化的深层关联，为英汉学术写作教学与跨文化发表提供参考。

Abstract: As a linguistic resource that indicates the source of information and cognitive stance, evidentiality plays an important role in the construction of authorial identity in academic discourse. This study, based on a self-built corpus of 30,000 words of English and Chinese linguistics academic papers, employs the evidentiality classification framework by Liao and Weng (2022), combining quantitative and qualitative methods, to examine the impact of evidential resources on authorial identity in introductions and conclusions. The study finds that: (1) In introduction, English papers frequently use sensory and belief evidentials, constructing the identities of empirical observer and position declarer; Chinese papers often use reported evidential, presenting a literature reviewer identity. (2) In conclusion, English papers make extensive use of belief and sensory evidential, constructing the identity of confident theoretical contributor; the use of evidential in Chinese papers significantly decreases, with the authorial identity tending to withdraw. (3) English cultures encourage highlighting personal contributions in conclusions, while Chinese cultures prefer a modest and implicit conclusion style. This study reveals the deep connection between evidential choices and academic culture, providing references for English and Chinese academic writing instruction and cross-cultural publication.
