摘要：Retailers always face such a decision whether to add an online channel. This paper considers a supply chain made up of one manufacturer and one retailer and incorporates product web-fit as a variable in demand function. Furthermore, a Stackelberg game model is presented and the equilibria of price and profit with and without internet channel are compared. Theoretical analysis and numerical examples show that retailer always benefits from dual-channel when product web-fit is in a certain range, while whether the profits of manufacturer and the whole supply chain will be increased depends on the value of product web-fit.
