中文摘要：

基于BA无标度网络,构建了舆论和网络结构相互影响的自适应舆论演化模型.舆论的演化不仅受制于网络拓扑结构,而且也导致拓扑结构的变化.研究表明,演化达到稳态后,网络结构不再是初始的无标度网络而呈现泊松分布,而且随着时间的推移,系统中的舆论演化表现出很强的趋同效应,原来初始状态的几十个舆论,在长时间的演化后,大部分舆论灭亡,只有少数的舆论存留,且发展壮大.这种趋向与社会上的舆论、意见、信仰的演化大体上是符合的.

英文摘要：

Based on scale free network,the public opinion evolution model is constructed,in which the public opinion changes with topology （the relationship and the influence between the individual）. The model features that the network structure constantly changes in the process of evolution with evolution parameter 0. It is found that the evolution of the public opinion not only is controlled by the topological structure,but also induces the change of the topological structure： the network structure is no longer the initial scale-free network,but it has a Poisson distribution. With the time evolution in system,there is obvious convergence effect of the public opinions. The dozens of opinions in initial state evolve with time, but most of them perish and only a few of them can survive and develop for a long time. The evolution trend is coincident with that of the public opinions,views and beliefs in society.
