Abstract: To obtain the optimal decision of supply chain with renewal product,a price decision problem in product renewal supply chain constituted by one manufacturer and one retailer was studied. Aiming at the situation of renewal products and original products coexist in one supply chain, renewal products'increasing function and transfer function were built. The whole decision space was divided into four regions, and a market sale model for updated products was built based on these functions. By using this model, a Nash game model and a joint decision model for renewal product's combination pricing in two-stage supply chain were established, and the optimal strategy of products pricing as well as some properties in each region were obtained. For example, the optimal price of renewal product was higher than that of the original product in case of Nash game(non-cooperative game), but less than the sum of original price and product of renewal rate and original price; the profits increase along with the increase of the updating rate. These properties had reference significance for product renewal decision.
