环境事件中个体策略与群体策略选择的行为实验研究

The Behavior Experiment of Individual Strategy and Group Strategy Selection in Environmental Events

运用行为实验的研究方法,笔者对PX项目环境事件中实验对象的社会连接关系及其整体的社会网络结构进行刻画,并运用DeGroot模型刻画了实验对象在社会连接关系、有向网络图与信息交互、学习过程作用下的个体行为与群体行为状态的演化过程。研究结果表明在PX项目环境事件的实验对象中,孤点与小团体的存在使得整体社会网络密度较小,限制了群体中信息传播与观点交互;核心网络中的不同节点对其它节点的控制力与影响力存在显著差别;在研究试验对象的学习与行为策略演变规律时,在对小群体的社会网络拓扑结构与社会影响矩阵进行试验调查的基础之上运用DeGroot模型来进行刻画、预测是一种可操作的方案与途径。

This paper use behavioral experimental approach to characterize the social relationship and the whole social network structure of the experimental group in PX project environmental events. This paper also use DeGroot model to depict the evolutionary process of individual and group behavior under the influence of social relationship, directed network, information interaction and learning process. The result shows that in PX project environmental events the whole social network has low density because the existence of acnodes and cliques. They so restricted the information transmission and interaction in the group. Different nodes has different controlling force and influence in the core network. On the basis of experiment and investigation of the group＇s social network topology and social influence matrix, using I）eGroot model to depict and predict the evolution of the experimental group＇s opinion and behavior strategy selection is an operational method.
