中文摘要：

微博舆情的传播主要靠用户来推动。在《解释》出台的背景下，从用户感知、偏好和涉入三方面着手，结合信任因素，构建了影响微博舆情传播意愿的模型，并运用结构方程模型对所构建模型和假设进行了实证研究。研究结果表明，感知风险负向作用于舆情传播意愿，用户涉入及事件关注偏好对舆情传播意愿具有积极影响，而信任信源偏好、感知信息质量则通过影响信任的形成进而对舆情传播意愿产生积极作用，此外，信任负向影响其感知风险。

英文摘要：

Microblogging public opinion propagation is driven by users primarily. In the background of issued the “interpretation”, we proposed a theoretical model which show the influencing factors affecting microblog users＇ willingness to propagate public opinion. This model adopteds several factors of three aspects, users＇ perceptions, preferences, and involvements, combination with the trust factor. Furthermore, theoretical model and relevant hypothesizes are verified via empirical research. The results shows that perceived risk has negative effect on users＇ propagation willingness, while users＇ involvements and event concerned preferences have positive effect on propagation willingness. In addition, perception information quality and preferences of trust source have indirectly influence on users＇ propagation willingness. Meanwhile, trust has a negative effect on perceived risk.
