舆论形成是个体因素与外部影响共同作用的结果.个体因素包括个体理性的认知与非理性的情绪因素,外部影响则包括文化、认知以及行为模式的作用和社会网络上个体之间的影响,而文化、认知等背景因素往往与空间地域相关联.本文通过构建一个同时具有空间位置特征与小世界特征的无标度网络以及网络上的Ising模型,全面考察了空间与网络共同作用对舆论形成的影响,研究了舆论形成中的相变行为,重点分析了与区域文化或认知背景以及与整体社会情绪等相关的参数在舆论形成过程中的作用.计算机数值模拟结果表明,区域间的认知背景差异足够大时,会导致公共舆论形成明显的区域性特征,此时,空间因素和社会网络具有同样的影响强度时,会有利于全局一致舆论的形成.同时,非理性因素引发的社会情绪可以通过提高个体影响力及降低背景差异使得一致性公共舆论快速形成.
The formation of public opinion is the result of the interaction of individual factors and external influences, including individual rational cognition and irrational emotional factors, external influences including the role of culture, cognition and behavior patterns and the influence of individuals on social networks , And background factors such as culture and cognition tend to be associated with spatial regions.In this paper, we construct a scale-free network with both spatial and mini-world features and an Ising model on the network, and examine comprehensively the interaction between space and network The formation of public opinion, the study of the phase change behavior in the formation of public opinion, focusing on the analysis of regional culture or cognitive context and the overall social mood and other parameters related to the formation of public opinion in the process of numerical simulation results show that inter-regional When the difference of cognitive backgrounds is large enough, it will lead to the formation of obvious regional characteristics of public opinion. In this case, when the spatial factors and social networks have the same influence intensity, it will be conducive to the formation of a unified consensus. Meanwhile, irrational factors Social emotions can be made consistent by increasing individual influence and reducing background differences Rapid formation of public opinion.
