Abstract:

We proposed the idea of modeling the large value payment system of China by means of the theory and methods of complex networks to solve the problem of measurement of the node strength distribution of this network. Based on the regional payment data, through this study we found that two network nodes strength distribution follows the power law distribution, but the exponents are different. These two exponents will vary with the setting threshold value. They all do not have small world characteristics.

Key words: the large value payment system, complex networks, node strength distribution, power law distribution, small world networks
