Power-law distribution for moral hazards in supply chain

The objectivity is to obtain the evolution law of moral hazards in supply chain, and to control it effectively. A Multi-Local-World directed networks model according to persons´ interacting rules, is constructed to specify the evolution law of topological of the moral hazards in supply chain. Using the method of complex networks, the topological structure´s evolution law is gotten. The result shown that, the Multi-Local-World directed networks model of supply chain´s moral hazards satisfies power-law distribution, is a scale-free networks, the component is decided by ß_i, the character of the supply chain.
