中文摘要：

为研究TPL服务竞争对零售商物流外包供应链结构的影响,针对一个零售商和两个相互竞争的TPL构成的供应链系统,运用Stackelberg博弈分别从三种权力结构分析供应链成员的均衡策略.研究发现,市场竞争的不同阶段影响供应链权力结构,当竞争强度不大时,各方均愿意选择零售商主导的供应链结构,仅当竞争强度很大时,各方更愿意选择自己主导的供应链结构.而对于市场消费者,零售商主导供应链时可获得更好的福利.

英文摘要：

To study the service competition from TPLs impact on the supply chain structure of retail logistics outsourcing, we consider a single retailer who wishes to outsource the demand at a fix price to two competing TPLs. A game-theoretic framework is applied to obtain the equilibrium solutions for every entity. We study and compare results from three possible noncooperative games of difference power structure between TPLs and retailer： 1） Retailer Stackelberg; 2） TPL Stackelberg; 3） Vertical Nash. We found that the competitive intensity has great effect on the power structure of supply chain. Every member prefers the Retailer Stackelberg structure while the competitive intensity is weak. However, all channel members are willing to be the leader while the competition is fierce. Consumers are better off when the Retailer dominates the market. By numerical analysis, the equilibrium decision variables and profit of each participant is discussed, which is affected by the competitive intensity.
