摘　　要：[目的/意义]旨在探究社交网络环境下用户健康信息分享意愿的形成机理,为社交健康网络的开发者、设计者和运营者的实践活动提供可供参考的管理启示。[方法/过程]基于"深度访谈+扎根理论"获取二阶信息链(含二阶信息链、二阶信任链)分析框架下社交健康信息生态链中信息内容与信息信任的作用机理,并通过整合感知价值理论、信任理论、技术接受模型中提取出的关键因素,从信息主体、信息环境、信息内容及信息技术4个层面展开系统分析,提出研究假设并构建理论研究模型。选取微信的深度用户为实证样本,通过"情境实验+问卷调查"的方式获取400份有效数据样本,并采用结构方程模型的研究方法验证理论模型。[结果/结论]信息主体因素(分享价值、自我效能及面子意识)、信息环境因素(分享态度、信源引力认知信任与情感信任、信宿推力认知信任与情感信任)、信息内容因素(信息正向情绪性、信息负向情绪性)均能显著正向影响社交网络用户的社交健康信息分享意愿,而信息技术因素(感知有用性、感知易用性)对分享意愿无显著影响。[Purpose/Significance]This article aimed to explore the formation mechanism of users willingness to share health information in social networks,and to provide management inspiration for social network developers,designers and operators.[Method/Process]Based on the"in-depth interview and grounded theory",the mechanism of information content and information trust in the ecological chain of social health information under the analysis framework of second-order information chain(including second-order information chain and second-order trust chain)was obtained,and analysis was developed by integrating the key factors extracted from the perceptive value theory,theory of trust and technology acceptance model,as well as conducting systematic analysis and proposing the research hypothesis model from four aspects,which included information subject,information environment,information content and information technology.The in-depth users of WeChat were selected as empirical samples and 400 valid data samples were obtained through"situational experiment and questionnaire survey",and the theoretical model was verified by the research method of structural equation model.[Result/Conclusion]Information subject factors(share value,self-efficacy and face concern),information environment factors(sharing attitude,information source attraction cognitive trust and emotional trust,information sink impetus cognitive trust and emotional trust),information content factors(information positive and negative emotion)were all have significant positive effect to the social network users health information sharing willingness.However,Information technology factors(perceived usefulness,perceived ease of use)had not significant effect on sharing willingness.
