供应链道德风险的演化规律

摘要

建立了以人为粒度(agent)的供应链道德风险有向多局域世界网络模型,给出了供应链道德风险的定义,确定了供应链道德风险复杂网络中人与人之间相互作用的交互规则及网络的演化规则,采用复杂网络分析方法,证明了供应链道德风险复杂网络拓扑特性的演化规律——其网络服从幂律分布,供应链道德风险多局域世界复杂网络满足无标度特性,该幂律取决于供应链特性的大小.%A multi-local-world directed networks model based on persons' interacting rules is given, the moral hazards in supply chains are defined, and the evolution law of topological features of the moral hazards in supply chain is given. So, the interactive rules between agents in this complex networks are quantified. The evolution law of the topological structure' s character, is proven to conform to power-law distribution. The result shows that multi-local-worlds of moral hazards in supply chain must be a scale-free, with the component being decided by the character of the supply chain.
