Understanding supply chain network are important for modeling the spread of risks in enterprise nodes. This paper characterizes the supply chain risk network of the spread of several nodes. To identify the rule of the movement of risk nodes, several parameters describing these properties are measured (degree, risk, the number of risk nodes, average risk, average path length and average clustering). The simulation results indicate: this risk network has small-world and scale-free property; the basic topological characteristics on static network displayed a regular change; the characteristics of the spread of risk is measured by risk distribution which obeys a double power law and average risk which has a negative correlation with the number of risk node.
