On the topological properties of urban complex supply chain network of agricultural products in mainland China

Abstract

Based on the complex network theory, we investigated the urban supply chain network of agricultural products in mainland China. Our research shows that the degree distribution of the urban supply chain network of agricultural products in mainland China follows the power-law behavior, and the network has scale-free and high disassortative properties. In this paper, the scaling exponent of the degree distribution of the network is calculated with two methods, the degree correlations of the network are studied, and the assortativity coefficient of the network is calculated. The network displayed high disassortativity in its degree. These properties found in the urban supply chain network of agricultural products in mainland China are very different from other social networks.
