Abstract: When the retailer had incomplete information on the suppliers' innovation efficiency in a supply chain composed of two competitive suppliers and a monopolistic retailer, the research on how to design the auction mechaism for the retailer to assign the order so as to promote the competition among the suppliers, thus motivate the supplier to make innovation to reduce the cost, and the retailer could purchase in low price was proposed. The suppliers' innovation efforts and retailer's profit were studied under three kinds of auction mechanisms, first-price sealed auction, halving order auction and second-price sealed auction. Conclusions showed that the suppliers' efforts increased as the innovation efficiency improved; the retailer's expected price of procurement rose with the increasing discrepancy of the two suppliers' innovation efficiencies, and first-price auction was the most profitable for the retailer among the three auction mechanisms. The results were verified by numerical examples.
