摘要
对包含两个子网络的复杂金融网络进行了分析,研究了网络中各节点收益率与资金流通量之间的关系.通过建立数学模型,证明了网络中各节点收益率加权和的不变性.
A complex financial network consisting of two sub-networks was studied by analyzing the relationship between the rate of return and amount of circulating fund at each node in the network. The invariance of the weighted sum of rates of return for each node in the network was proved by establishing a mathematical model.
