摘要 Abstract of the Paper	This article establishes a duopoly vertical supply chain model, in which a monopoly manufacturer authorizes the products to two dealers, a CSR dealer, and a PMF dealer, in the form of the input price. We analyze the optimal degree of CSR and explore the impact on consumer surplus and social welfare. The results show that when a manufacturer sets a uniform price for two dealers, the manufacturer's profit, consumer surplus, and social welfare will be higher than in the case of discriminatory pricing. Regardless of whether the manufacturer uses uniform or discriminatory pricing authorization, the overall industrial profits, consumer surplus, and social welfare are higher when the CSR dealer belongs to the direct selling store rather than the franchise store. When a manufacturer adopts uniform pricing at the direct selling store, it is the highest channel coordination method for social welfare; but at the same time, CSR will become a tool to concentrate the market, drive PMF dealers out of the market so that manufacturers can extract all of the industry profit.
