The Empirical Study of Polarization in Blog Communication

Polarization, one of the phenomenons emerging from blog communication, is affected by multiple factors during its formation and evolution. This paper sets up the dynamic model of blog communication based on social impact theory, uses empirical analysis to research three aspects of social network, which are the composition of the initial opinion, the fixed opinion groups and subjective mental preference of interactive groups. And the research result shows that polarization is not only related to the structure of social network but more influenced by the subjective mental preference of interactive groups.
