摘要社会化问答社区在近年来取得了极大的成功。为了激励用户持续参与知识分享活动,声誉系统被广泛地内置于社会化问答平台的交互功能中。本论文旨在从需求方角度研究声誉系统对知识分享活动的作用,探究并区分流行度影响和在线口碑是否存在于社会化问答社区中。本文以"知乎"数据为研究对象,构建了面板数据,设定动态面板模型,利用系统化广义矩估计方法进行参数估计。研究结果表明,流行度影响和在线口碑确实存在于社会化问答社区中。研究结论在理论和实践上对社会化问答社区的运营管理实践有启示作用。 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.
