英文摘要：

The emergence of B2B online exchanges has provided manufacturers and retailers a new avenue to do their business, and thus has changed supply chain structures. This paper investigates the strategies of a manufacturer and a retailer in a decentralized supply chain with a fully liquid B2B online exchange. The manufacturer, as a Stackelberg leader, determines the wholesale price and the production output; while the retailer, as a follower, determines the retail price and the quantity to be ordered from the supplier prior to the selling season. During the selling season, both the manufacturer and the retailer can trade in the B2B online exchange. Our study shows that for the retailer, the B2B electronic market can serves as a speculation market or a second procurement source. Correspondingly, by using the pricing strategy, the manufacturer can achieve bully or risk-sharing intentions.
