银行账户交易复杂网络特性分析

首先基于银行账户交易的特点,建立了一个有向加权的银行账户交易网络通用模型。进而,根据复杂网络的定义,从网络结构和节点2个层面,验证了交易网络的复杂网络特性。其中,网络结构特性包括静态特性（即无标度特性和小世界特性）和动态演化特性（即自组织特性）。此外,使用吸引子特性验证了复杂网络节点的动力学特征。分析包含非法传销交易的真实银行交易数据,得出如下结论：该网络具有无标度特性、小世界特性、部分自组织特性和奇异吸引子。

Analyzing the complex properties of bank account transaction network

Firstly,a general directed and weighted transaction network model is built on the basis of the transaction characteristics of bank accounts.Secondly,referring to the definition of complex network,the complex network properties of the transaction network are verified from two levels of network structure and node.The network structure properties includes static properties,named scale-free property and small-world property,and dynamic evolution property,that is self-organization property.In addition,the attractor property is utilized for verifying the dynamical characteristic of complex network nodes.Finally,on the real bank account transaction data contains illegal pyramid marketing activities,the following conclusions were drawn:the network has scale-free property,small-word property,partially self-organization property and strange attractors.
