选前民意调查的动态意见形成模型

On a kinetic opinion formation model for pre-election polling

Bertram Düring, Oliver Wright

摘要:

最近的成功基于模型的选举前民意调查的动机,我们提出了一个动力学模型的意见形成,其中包括选民的人口统计和社会经济因素,如年龄,性别,种族,教育水平,收入和其他可衡量的因素,如在以前的选举或公民投票的行为作为一个关键的驱动程序的意见形成动态。该模型基于Toscani的动态意见形成模型和Düring等人的领导者-追随者模型,并导致耦合玻尔兹曼型方程和相关的近似福克-普朗克型系统的系统。数值例子使用的数据在英国大选显示不同的人口对意见形成过程和选举结果的影响。

英文摘要:

Motivated by recent successes in model-based pre-election polling, we propose a kinetic model for opinion formation which includes voter demographics and socio-economic factors like age, sex, ethnicity, education level, income and other measurable factors like behaviour in previous elections or referenda as a key driver in the opinion formation dynamics. The model is based on Toscani's kinetic opinion formation model and the leader-follower model of Düring et al., and leads to a system of coupled Boltzmann-type equations and associated, approximate Fokker-Planck-type systems. Numerical examples using data from general elections in the United Kingdom show the effect different demographics have on the opinion formation process and the outcome of elections.
