需求改善投资下制造商入侵与平台信息分享OA

Based on a supply chain consisting of a manufacturer and an e-commerce platform,this paper examines the interaction mechanisms between manufacturer encroachment and platform demand information sharing in the context of demand-enhancing investments undertaken by the manufacturer.Based on whether the manufacturer pays a commission to the platform to open an agency channel and enter the platform(i.e.,encroachment)and whether the platform shares demand information with the manufacturer,it develops four incomplete-information dynamic game models.The findings reveal that when investment efficiency is either high or low,manufacturer encroachment has no significant effect on platform information sharing.However,when investment efficiency is at a moderate level,sharing becomes complementary:manufacturer encroachment promotes platform information sharing,and platform information sharing further enhances the manufacturer's incentive to encroach.When investment efficiency is moderately high,increasing the commission rate leads to the equilibrium strategy profile to transition along the path of"encroach+non sharing→encroach+sharing→non encroach+non sharing".During this transition,the manufacturer's(platform's)profit exhibits upward(downward)jumps and shows a non-monotonic relationship with the commission rate.Additionally,when the commission rate is low and investment efficiency is high,encroachment increases the wholesale prices in the resale channel,a result that differs from previous literature.
