【摘要】 “知识过载”、“知识迷航”、“供需不匹配”、搜寻和筛选知识耗时耗力已经成为在线问答社区中的顽疾，如何在此背景下提高答案的采纳已经成为社区和学者们研究的重点。基于此，文章从在线互动的视角出发，采用信息采纳模型，研究答案的内容特征（文本特征、修辞特征、情感特征）和答案提供者的社区地位（官方地位、意见领袖地位）对答案采纳的作用，并探讨答案互动程度的中介作用。文章以知乎为研究对象，采集了学习话题下1 696条答案信息，运用SPSS 24对数据分析以验证模型。研究结果表明：答案的文本特征、修辞特征和答案提供者的社区地位积极影响答案采纳；答案的文本特征、修辞特征和答案提供者的社区地位积极影响答案的互动程度；答案的互动程度在答案的内容特征（文本特征、修辞特征）对答案采纳、答案提供者的社区地位对答案采纳之间的关系中起部分中介作用。更多还原

【Abstract】 “Knowledge overload”, “knowledge lost”, “supply-demand mismatch” and the time-consuming and laborintensive search and filtering of knowledge have been haunting online Q&A communities. As such, how to improve the answer adoption has become the key to research by communities and scholars. On this basis, this study investigated the content characteristics of answers(textual characteristics, rhetorical characteristics, emotional characteristics)and community status of the answer provider(official status, opinion leader status) on answer adoption, and explored the mediating role of the degree of interaction of the answer from the perspective of online interaction based on the Information Adoption Model(IAM). Taking Zhihu as the research object, this study collected 1 696 items of answer information under the learning topic, and analyzed the data through SPSS 24 to verify the model. The findings show that: the textual characteristics and rhetorical characteristics of answers, and the community status of answer providers positively influence answer adoption; they actively influence the degree of interaction of the answer; and the degree of interaction plays a partial mediating role in the relationship between the content characteristics of the answer(textual characteristics and rhetorical characteristics) and the answer adoption, and the community status of the answer provider and the answer adoption.更多还原
