主要探讨网络形成模型中个体连接搭档异质性对有效网络结构的影响。由于个体在财富、地位、知识等方面的差异性,导致网络形成过程中个体偏好选择具有较高价值的个体成为连接搭档。因此在Jackson和Wolinsky(1996)提出的连接模型基础上,考虑当个体连接成本与得益由其连接搭档决定时,相较与同质性个体,其有效网络结构的变化。研究表明搭档异质性在增加有效网络的多重性及结构的复杂性等方面起了主要作用。
Mainly discusses the network formation model in the individual connection partner heterogeneity on the effective network structure. Due to the differences in the wealth, status, knowledge and other aspects of the individual, individual individuals with higher preference in the process of network formation become the connection partners. Therefore, on the basis of the connection model proposed by Jackson and Wolinsky (1996), we consider the change of the effective network structure of individual compared with homogeneity when the cost and benefit of individual connection are determined by their connection partners. Research shows that partner heterogeneity plays a major role in increasing the multiplicity of effective networks and the complexity of the structure.
