A Contrastive Study of Lexical Cohesive Devices in Financial Academic Paper Abstracts

English abstracts of financial and economic academic papers are an important medium for academic communication, and their clarity and consistency are crucial for international readers to understand and cite.Lexical cohesion, as a key component of discourse analysis, has a significant impact on the logical structure of a summary and the efficiency of information transmission.However, academic writing in different linguistic contexts may differ in lexical cohesion strategies, which may affect the international readability and impact of abstracts.Using Halliday's discourse cohesion theory as an analytical framework, this study compares lexical cohesion devices in abstracts of Chinese and English financial academic papers through quantitative and qualitative analysis methods.First, this paper uses the corpus analysis tool to conduct word frequency statistics and co-occurrence analysis on the collected abstracts to identify common cohesive words and phrases.Then, this paper makes an in-depth qualitative analysis of the functions and effects of these cohesive devices in the discourse, and discusses how they promote the coherence and logic of information.It is found that English abstracts tend to use more references and articulation devices, with MATTR values up to 0.91, lexical articulation frequency up to 92% and discourse coherence score up to 84.These differences reflect the culture and habits of English in academic writing.The research results have practical significance for guiding the writing of English abstracts of financial and economic academic papers.
