在网络外部性情境下,考察网络外部性强度、竞争强度和市场风险对竞争供应链结构选择的影响,分别从制造商与供应链的角度出发,识别竞争供应链的纵向结构选择策略和动态演化均衡.基于制造商的结构选择受市场风险波动范围和竞争强度的影响,竞争强度边界和风险的范围依赖于网络外部性强度系数,在不同的网络外部性环境下,竞争强度和风险对制造商的结构选择的影响作用不同;基于供应链系统的控制结构选择与市场风险无关,仅与依赖于网络外部性强度的竞争强度有关.
Under the circumstance of network externalities, the influence of network externalities, competition intensity and market risk on the selection of competitive supply chain structure is investigated. From the point of view of manufacturer and supply chain, the vertical structure selection strategy and dynamic evolution of competitive supply chain Equilibrium.Based on the structural choice of manufacturers, which is affected by the fluctuation range and intensity of market risk, the scope of competition intensity boundary and risk depends on the intensity coefficient of network externalities. In different network externalities, The choice of control structure based on supply chain system has nothing to do with the market risk, but only with the intensity of competition which depends on the strength of network externalities.
