Study of Exploring Hidden Relationship Among Commercial Bank Customers Based on Complex Network Theory

Qian SU, Guanghui YAN


Commercial banks are very keen to understand the relationship among their customers, but it is difficult to get directly. This paper proposes a method using the transaction behavior data between customers, combined with complex network theory to establish a network on relationship of customer transactions, so as to obtain the hidden relationship among customers. Based on real bank customers 3 months of transfer transaction records, we established Transaction complex network model of bank customers. The quantitative analysis of the complex network model shows that it satisfies the characteristics of scale-free and small world networks. This study demonstrate an approach by applying complex theory to solve customer relationship management problems, and the findings are helpful for banks’ in depth analysis of their customers.
