Abstract: From the perspective of supply chain management, game theory was used to construct models for three modes, by which manufacturers provided product and extended warranty services to consumers. And the extended warranty services desirability index was also introduced to analyze. Analysis results revealed that：(1) Only part of consumers who purchased the product with the extended warranty services, the manufacturer was benefited when the extended warranty service was provided by the retailer. But the retailer had to balance the relation of the extended warranty services desirability index to choose the optimal mode between the M and R modes. (2) All consumers who purchased the product with the extended warranty services, both the manufacturer and the retailer had to balance the relation of the extended warranty services desirability index to choose the optimal mode. (3) When the extended warranty services desirability indexes were equal, retailer provided the extended warranty services could benefit both of manufacturer and retailer.
