Identity construction of agriculture-related enterprises is an important part of enterprise development and external publicity,but its importance is often underestimated.Based on the quantitative research method of corpus,this paper takes Fairclough's three-dimensional discourse analysis model as the theoretical framework,analyzes the linguistic features of the New Hope Liuhe and Corporate Social Responsibility Report(2019-2021)(English)from the perspectives of high-frequency nouns,high-frequency verbs,modal verbs,and concordances and collocations of high-frequency words,puts forward the critical discourse analysis of the identity construction of agribusiness enterprises based on the corpus framework,and explores the ideological factors behind the corporate identity of New Hope Liuhe from the two perspectives of discourse practice and social practice.The study shows that the corporate identities constructed in New Hope's CSR report are mainly those of patriots,social contributors,environmentalists,staff carers and practitioners of the customer-first belief.This study has reference value for improving the international discourse construction ability of Chinese agribusiness enterprises,and can help local agribusiness enterprises to improve their communication capabilities.
