考虑服务商竞争的物流服务团购研究

针对单个集成商、两个竞争服务商所组成的物流服务供应链,首先分析了各成员分散采购和团购策略下的均衡数量、均衡价格以及最优利润。在此基础上,对两种策略下的均衡值进行比较分析。通过数值验证,得到如下结论:对于服务商而言,当市场规模相同时,团购策略总是有利的;当市场规模差异较大时,团购策略对市场规模大的一方有利,对市场规模小的一方不利。对于供应链而言,团购策略使得整体效率得以提升。

Research on Group Buying of Logistics Service Considering Competing Providers

For the logistics service supply chain composed of a single integrator and two competing providers,we first analyzed the equilibrium quantity,equilibrium price and optimal profit under the individual purchasing and group buying strategies of participants.Then,comparative analysis of the equilibrium value under the two strategies was carried out.Through numerical verification,the following conclusions are obtained:when the market basis is the same,the group purchase strategy is always advantageous for service providers;when the market basis is different and the difference is obvious,the group buying strategy is beneficial to the provider who has larger market base,bad to the smaller one.For the supply chain,group buying strategies have improved overall efficiency.
