Abstract: 【Purpose/significance】The mobile professional virtual community in the era of digital intelligence has become an impor⁃tant way for users to acquire, share and innovate domain knowledge. This paper attempts to explore the user demand level, in order to provide a useful reference for the construction of mobile professional virtual community resources and service models in the digital in⁃telligence environment.【Method/process】This paper uses the grounded theory method to conduct in-depth interviews with 19 users to obtain original data, and obtain conceptual categories and their logical relationships through three-level coding, which specifically covers 6 main categories, 19 categories and 71 initial concepts, condensing the mathematical intelligence A theoretical model of user needs (SUR) of mobile professional virtual community in the environment.【Result/conclusion】The research results show that the user
needs of mobile professional virtual community present three dimensions: user, resource and service. From the main category relation⁃ship structure, it can be seen that content demand and basic services constitute the construction factors of mobile professional virtual community user demand, and user cognitive benefit and social utility play an internal driving role in the generation of mobile profes⁃sional virtual community user demand under the digital intelligence environment. Content quality and service optimization play an ex⁃ternal driving role in the generation of user demands of mobile professional virtual community in the digital intelligence environment.
【Innovation/limitation】The user demand model proposed in this study provides a useful reference for the service optimization of mo⁃bile professional virtual communities in a digital intelligence environment. Subsequent research can verify the scientificity and ratio⁃nality of the model through empirical methods.
