Abstract: In a heterogeneous demand market,two Closed-Loop Supply Chain (CLSC) models composed of manufacturer,remanufacturer and retailer under different patent licensing mode were studied,which were fixed patent licensing fees model and unit patent licensing fees model.Through analyzing these two models,the equilibrium solution of decision-making variable and optimal profit of CLSC were obtained|through comparing these two models from the respect of manufacturer's profit,return rate and retail price,the fixed patent licensing fees model was proved to be good for environment protection and consumer welfare.However,the better CLSC with which kind of patent licensing mode depended on different conditions for manufacturer.The impact of remanufacturing cost saving and consumer acceptance of remanufacturing products on the CLSC model with different patent licensing was analyzed by using numerical simulation method.
