摘　　要：观点共识与分化通常会对社会系统产生深刻影响,因而备受关注.将Sznajd的离散观点推广为连续观点,并且基于最近邻和次近邻之间观点的不同影响机制建立动力学模型.模拟结果表明,在不同强度的最近邻和次近邻作用下,系统稳态呈现观点一致和观点分化两种情况.相关细节对深入理解观点演化具有一定意义.Consensus and/or polarization of opinions usually have a profound impact on the social system and thus attract widespread attention from researchers in different fields.In the real world,the opinions of people evolve through the exchange of opinions and mutual influences with other people.In this paper,the discrete opinion of the Sznajd model is extended to a continuous one,and a new dynamical model is established based on the different influence mechanisms of the views between the nearest neighbor and the next nearest neighbor.The simulation results show that the steady state of the system presents two cases of opinion consistency and opinion divergence under different nearest neighbor and next nearest neighbor strength.The relevant details have certain significance for in-depth understanding of opinion evolution.

关 键 词：Sznajd模型 观点演化 邻居影响 幂律关系
