| 摘 要： | 目的/意义]旨在探究线下社会资本水平不同的用户,在问答社区中累积的社会资本和问答社区行为是否存在差异。方法/过程]以知乎网10个医学、健康类话题的6 927名用户为研究对象,借助职业声望、院校排名对其线下社会资本进行编码和排序,分析不同线下社会资本用户的线上社会资本积累和社区行为模式的特点。结果/结论]部分线下社会资本如毕业院校名誉度与线上社会资本存在正向关联,但职业声望高低则与线上社会资本无关;线上结构性社会资本高的用户,其提问数量、专栏文章数量和关注人数较高,而线上认知性资本高的用户,其回答数量和专栏文章数量较高。这些结果有助于网站管理者识别、关注核心用户、优化用户激励制度,但样本用户为医学、健康话题参与者,结论普适性还有待验证。

| Abstract: | Purpose/significance] This study aims to explore the relationship between users' online and offline social capital and their online behavior in a social Q&A site:zhihu.com. Method/process] We collected profile information and activity data of 6 927 users from 10 medical and health topics, and analyzed the characteristics of online social capital accumulation and community behaviors of users. We ranked different offline social capitals. Result/conclusion] 1) Some offline social capital such as the ranking of universities users graduated from is positively related to his/her cognitive and structural online social capital. However, the job position level is not related to the online capital. 2) Users with higher offline capital contributed more answers. 3) Online structural capital is positively related to the number of questions, articles, and followings; whereas, online cognitive social capital is positively related to the number of answers and articles. These results may help site managers to identify core users and optimize the user motivation mechanism. Our sample users are participants in medical and health topics, so the generalizability of the conclusions should be further examined. |
