考虑网络外部性航运商与无车承运人竞合研究

构建由 1个海洋航运商和 2个无车承运人组成的上下游的合作与竞争关系，2个无车承运人有不同的市场地位.通过斯坦伯格博弈研究发现，航运商负责货源或处于领导地位的无车承运人负责货源会影响各方的均衡利润及渠道结构.分析比较了海洋航运商的整合策略和利润共享策略.结果表明，在网络外部性和无车承运人提供差异性服务时，纳什均衡是航运商负责货源且上下游整合或利润分享.

Co-opetition Between Ocean Carrier and Freight Forwarders with Network Externality

It is studied that the competition and vertical cooperation between one ocean carrier and two freight forwarders. In addition, two freight forwarders have different market positions. We observe that the ocean carrier or freight forwarders canvass for cargos, which influences the equilibrium profits and channel structures in Stackelberg game. We show the integration and sharing between the ocean carrier and freight forwarders. Comparing parties’profits with profit sharing or integration depended on network externality and product differentiation, we find that the Nash equilibrium is the ocean carrier canvasses for cargos and the integration or sharing.
