摘　　要：提出了供应链经济中市场链理想生成与动态演进的超网络模型.对于有弹性市场需求的供应链经济,给出了均衡点的变分不等式模型.由此变分不等式的解可以确定各个市场链和供应链的流量、市场需求、市场价格以及市场份额.同时还给出了均衡的存在性与唯一性的条件.讨论了含时间参数的动态模型,对市场链的动态演进利用投影动态系统进行描述.A super network model for ideal formation and dynamic evolution of market chains was presented.For a supply chain economy with elastic demands,a variational inequality formulation of the equilibrium point was given,whose solution can be used to determine all the chain flows and link flows,the market demands,market prices,and market shares in the equilibrium.The existence and uniqueness of the equilibrium point were proved under reasonable conditions.The dynamic evolution of the market chains and their inter-chain competition can be modeled as a projected dynamical system.
