Abstract： As a new social network platform, microblog played a very important role in the information distribution and public opinion propagation, with its convenient usage, rapid propagation and strong interaction. This paper briefly introduced the mechanisms in microblog, analysed the characteristics and three influential factors of information dissemination.

Finally, it presented the future research trends and goals.
