Abstract:

From the perspective of trust, this paper creates an opinion evolution model integrating the internal and external factors, which involves trust among members, leadership trust and media trust. The experimental results of simulation show that the higher the mutual trust level of the community members and the higher the degree of members’ openness, the faster the community view evolves to a stable state. It takes a long time for opinion leaders in the community to play their full role. Maintaining a high level of trust and more social contacts with members will help leaders guide community views closer to those of leaders. The degree of trust of community members in the media will affect the effectiveness of media intervention, and the reverse phenomenon will become more apparent as the degree of intervention increases. Members’ positive impressions of the media will help community views closer to those of the media.

Key words: community trust, opinion evolution, small world network, media intervention
