文章利用扎根理论探索交流可见度调节下在线知识共享网络用户知识分享的影响因素，旨在推动在线知识共享网络得到健康和可持续发展，推动知识分享和知识创新实践。根据研究主题设计了访谈提纲，通过深度访谈进行数据搜集，利用三级编码构建了理论模型并进行了理论饱和度检验。在开放编码中，先提取了495个初始概念，再通过范畴化处理提炼出知识分享行为等29个基本范畴。在主轴编码中，基于基本范畴提炼出14个主范畴。在选择编码中，将“知识分享”确定为核心范畴，发现社会资本、社会认知、心理授权、面子、时间压力、感知有趣、隐私担心、他人知识需求、知识分享主题、性格在交流可见度的调节作用下对知识分享产生直接影响。

This paper employs the grounded theory method to explore impacting factors of knowledge sharing by online knowledge sharing networks users with the moderating effect of communication visibility, aiming at facilitating healthy and sustainable development of online knowledge sharing networks, facilitating knowledge sharing and innovation practice. The interview outline was designed according to the research topic and data were collected by in depth interviews. Three levels of coding were used to develop a theoretical model and the saturation was verified. During open coding, 495 initial concepts were firstly elicited, and then 29 basic categories were elicited by categorization. During axial coding, 14 main categories were elicited based on basic categories. During selective coding, knowledge sharing was identified as the core category. It is found that social capital, social cognition, psychological empowerment, face, time pressure, perceived enjoyment, privacy concerns, others' knowledge need, knowledge sharing topics and personality traits have direct impacts on knowledge sharing with the moderating effect of communication visibility.
