Abstract: In 2022,the “Year of Generative AI” emerged,and generative artificial intelligence emerged as a popular production tool and discourse object,widely discussed in various sectors of society and driving the research wave of “AI+discipline”.The study focuses on relevant papers published in high-level academic journals in journalism and communication since the emergence of ChatGPT.It is found that the academic community has conducted a series of textual and discursive analyses on generative AI,but there is a relative lack of discussion on the technical entities involved.The study suggests that further attention should be paid to the theory of media infrastructure to improve the theoretical framework of disciplinary research.A “material form-discourse construction” analysis framework for generative AI research in the field of journalism and communication has been proposed,and unresolved issues worthy of in-depth attention from the discipline have been identified at different levels.At the material level,attention should be paid to the “foundational” function of data on generative AI,and the control and influence of generative AI should be enhanced through the construction of high-quality Chinese media corpora.At the discourse level,emphasis is placed on generative AI defining knowledge through “knowledge reshaping”,indirectly defining universal strategic capabilities.

Key words: generative artificial intelligence, media infrastructure, material, discourse, Chinese media corpus
