摘　　要：针对现实舆论环境中属于不同群体的公众之间仍可以相互交流的实际情况,提出了群体间交互的舆论演化规则,建立了包含群体间观点交互的舆论演化模型.文中分别分析了忽略和引入群体间交互前提下舆论的演化情况,指出群体间交互规则会对整个舆论演化产生巨大影响,在对引入群体间交互规则前后的舆论演化模型仿真后,发现群体间交互加快了舆论的整体演化速度,并促使两群体最终达到意见统一.仿真结果表明,该模型的统计结果与实际情况吻合,在一定程度上可以解释群体间交互所带来的影响,具有很强的实际意义.For the reality that people in different groups can still discuss in the real opinion environment, this paper presented opinion evolution formula, prescribed how people in different groups discussed, established a new opinion evolution model including discussion between people in different groups. This paper analyzed the opinion evolution instances with and without discussion between people in different groups, pointed out that the discussion between people in different groups can make great influence on opinion evolution. After making simulation, we discovered that the discussion between people in different groups can accelerate opinion evolution as a whole, and make people in these two groups agree on the same point of view. Simulation shows that the proposed formula meets with the reality, can explain the influence because of discussion between people in different groups, have a high significance of realism.
