摘要： 为了研究社会网络与社会财富之间的相互影响,提出一种复杂Agent动态网络模型。在糖域模型中,基于社会圈子网络的理论,赋予Agent不同的社会半径生成熟人网络,根据财富共享规则在熟人网络中选择朋友生成财富信息共享网络。网络中的Agent采用财富资源共享的朋友关系社会网络寻找财富,实现财富的首次分配,加入社会财富交易机制,Agent之间通过财富交易机制进行财富交易,实现财富二次分配。Agent财富分布的变化又会影响Agent的熟人网络和朋友网络,最终形成社会财富和社会网络协同演化。仿真结果表明,该模型能合理调整社会关系,有助于缩小社会贫富分化和发展良好的社会关系网络。

Abstract: This paper proposes a complex Agent network model to study the interaction between social networks and social wealth.The Agents take advantage of different social radius to form acquaintance networks based on the theory of social circles in the sugarscape.Meanwhile,the Agents choose friends to form the wealth-sharing network through the rules in the acquaintance network.The Agents find wealth in the friendship network of wealth-sharing to achieve wealth distribution for the first time.The network adds social wealth trading mechanism to deal with the distribution of wealth.Through trading,the Agents complete the second wealth distribution.The Agent’s wealth makes its acquaintance network and friend network change,which finally leads to the co-evolution between social wealth and social network.Simulation results show that this model can reasonably adjust social relations.It can minimize the social inequality,and good social relation network can be developed.
