摘要社会化问答社区的出现改变了原有的问答模式并拓展了知识获取的途径。回答者作为知识的主要贡献者，是促进问答社区内知识传递的核心要素。现有关于问答社区用户的研究普遍以用户的属性数据为依据，较少考虑使用个体连接所形成的关系数据进行分析。本文以中文问答社区“知乎”为研究对象，爬取了“流行音乐”和“英语学习”两个话题下的大规模数据，通过构建回答者关注关系网络，定义和量化直接连接和间接连接两类同伴关系，使用网络自回归模型探究同伴效应对知识贡献行为的影响。研究发现，回答者的知识贡献行为会受到直接和间接连接同伴效应的正向影响，但是间接连接同伴效应会随着回答者网络密度的增加而逐渐减弱甚至消失，聚类系数对回答者的知识贡献行为有负向影响。
