Abstract: To study the influence of channel service competition and customer acceptance of Internet direct channel on dual-channel supply chain, a competition model based on price and service sensitivity was established. The optimal decisions in centralized and decentralized supply chain were analyzed. The comparison of service level and supply chain profit between dual-channel and single channel was presented. Numerical analysis was conducted on profit allocation of supply chain under different customer acceptance of Internet direct channel. The results revealed that the optimal decisions in Stackelberg equilibrium of dual-channel supply chain led the demand of Internet direct channel to zero when service differentiation existed. The service competition between dual-channel contributed to more system profits with comparison to single channel. Furthermore the supply chain profit allocation between manufacturer and retailer was affected by customer acceptance of Internet direct channel. And the dominated manufacturer would choose the optimal strategy based on the customer acceptance of Internet direct channel.
