中文摘要：

微信使用中，人们会选择进行积极的自我呈现和形象管理，以寻求他人认可或羡慕。本研究主要探讨微信用户信息发布的影响因素。在已有的研究基础上进行技术接受模型的修正，使用问卷调查的方法进行数据的收集整理。研究发现，感知有用性可以和感知收益等其他因素较好地结合，对个人信息披露和信息发布行为意向产生正向影响；信任、感知风险、信息控制、实用性等因素可以和技术接受模型进行较好的结合，共同对个人信息披露及信息发布行为意向产生显著影响。个人性别、职业、年龄、收入等因素均对用户信息发布行为产生显著影响，为进一步研究微信用户信息发布行为的动机提供了实证支持。

英文摘要：

Individuals tend to present themselves actively in WeChat use to seek the approval from others. This study focuses on the influences in WeChat users＇ information behavior. Technology Acceptance Model is modified and redesigned based on existing studies, and we used questionnaire survey to collect data. Results show that perceived usefulness and benefits can combine together, performing a positive effect on personal information disclosure. Trust, perceived risk, information control, availability can perform a better combination with Technology Acceptance Model. They together have a significant impact on personal information disclosure and post intent. We also prove that gender, occupation, age and several demographic variables have influence on users＇ information behavior, which provides empirical support for further research on users＇ behavior in WeChat.
