Abstract Social question & answering communities (SQAC) have been more and more popular in recent years as a type of user repository. To incentivize users to share knowledge continuously, reputation systems are embedded. This paper aims at investigating whether the two major mechanisms of social influence, namely popularity influence and online word-of-mouth (WOM), exist in SQAC. Real-world data are collected from Zhihu, one of the most influential SQAC. We construct a panel dataset and specify dynamic panel models for econometric analysis. The empirical result from system GMM (generalized methods of moments) suggests that both mechanisms have positive impacts on the social endorsement of knowledge sharing. Theoretical contributions and managerial implications are also discussed.
