| 摘 要： | 网络外部性是影响网络产品需求的主要因素，人们依据自身偏好选择网络产品，而选择过程又影响到产品的网络外部性大小，所以网络产品市场均衡是消费者选择的不动点。通过将消费者选择理论、交通网络流量分配模型和无穷维变分不等式方法相结合，建立了刻画网络产品市场均衡的无穷维变分不等式模型，并给出了求解算法和实例分析。

| Abstract: | Network externality is a major factor influencing network products' demand.Consumers usually choose products according to their preference,which similarily modifies the utility of network externality.The market equilibrium of network products is a fixed point of customer choice.By using of customer choice theory,traffic assignment model and infinite dimensional variational inequality method,the market equilibrium model of network products is founded on infinite dimensional variational inequality.An algorithm is offered and a case is studied. |
