摘要：Social Q&A community provides a new way for users to acquire, exchange and share information, so it is of great significance to study user’s knowledge sharing behavior in social Q&A community. Based on the theory of social exchange, this paper takes Zhihu community as the research object, analyzes the factors that affect user’s knowledge sharing behavior in the social Q&A community, and conducts quantitative research through negative binomial regression. The results show that in Zhihu community, self-display, user recognition, social learning and other dimensions have a significant positive impact on user’s knowledge sharing behavior, but the degree of impact is different. Finally, according to the empirical results, the paper puts forward relevant suggestions and measures to better promote user’s knowledge sharing behavior.
