[Objective] Explore an opinion evolution model based on the information dissemination of micro-blog. [Methods] Analyzing three kinds of user behavior in the micro-blog network (including publishing, review, forwarding), this paper proposes a new opinion evolution model, which introduces the concept of Sensitivity and Activity to measure user's enthusiasm for getting new information and discussing with others. Based on the NetLogo platform, this paper discusses the influence of the parameters on the result of evolution firstly, and then contrasts with HK model by computer simulation. [Results] The trust threshold has the effect on the user's opinion. Sensitivity has a promotion effect on the communication of information. Activity can speed up the dissemination of information and promote user's opinion to be stable. [Limitations] At present, the research of the opinion dynamics is mainly based on the theoretical analysis and the experiment, so the model also need to expand data size to verify the adaptability of the theoretical model. [Conclusions] The presented model is based on the behavior of micro-blog users. The experimental results show that the model can describe the complex information dissemination and the update of the opinion in the micro-blog network.
