Abstract: 【Purpose/significance】AIGC has become an efficient channel for college students to obtain information. The analysis of the types and relationships of college students' information needs using AIGC can provide reference for AIGC institutions to improve the information service level and better meet the information needs of college students.【Method/process】Based on the research method of grounded theory, semi-structured interviews were conducted with 18 college students to obtain the original data, conceptual categories and logical relations were obtained through three-level coding, and a theoretical model of college students' information needs using AIGC was constructed. Then, through questionnaire survey, exploratory factor analysis and confirmatory factor analysis were used to empirically test the theoretical model.【Result/conclusion】The results show that the information needs model of college students using AIGC includes 3 core categories and 6 main categories, basic service and information quality drive the information needs of college students using AIGC, content requirements and value-added service are two types of information needs of college students using AIGC. Information contribution is the embodiment of basic information literacy of college students who use AIGC. Benefit cognition is the goal of AIGC use by college students. The satisfaction of information needs and the improvement of information literacy will help the college students who use AIGC to realize their usage goals.【Innovation/limitation】The information needs of AIGC college stu⁃ dents is studied, and the information needs model of AIGC college students is constructed. But only ChatGPT, a mature AIGC applica⁃ tion product, was selected as an example for the study, and the research scope needs to be expanded in the future.
