英文摘要：

This paper aims to examining the factors influencing content regarding emergency events forwarding from a perspective of information source. We built a research model that six information source characteristics were integrated into three dimensions. The hypotheses deriving from this model were empirically validated by analyzing 12361 posts containing ＂Kunming terror violence case＂ which were collected by reptile software on the platform of Sina Weibo. Our findings implied that except for self-disclosure and the ratio of fans and concerned people, the grades, the number of posts and the number of fans positively affected forwarding behavior, while source authoritativeness negatively affected forwarding behavior.
