Abstract: The issues of closed-loop supply chain (CLSC) recovery, carbon emission reduction and patent authorization decision considering consumers' low carbon preference are studied in this paper. The CLSC models of manufacturer recycling and remanufacturing, retailer recycling and remanufacturing with fixed technology authorization fees and retailer recycling and remanufacturing with unit technology authorization fee are constructed respectively. The influence of the proportion of low-carbon consumers, ordinary consumers' acceptance for remanufactured products and carbon trading price on recycling strategies, carbon emission reduction and pricing decisions are analyzed. The profits of enterprises and CLSC under the three models are compared. It shows that with the increase of the proportion of low-carbon consumers and the acceptance of remanufactured products by ordinary consumers, the recovery rate and the carbon emission reduction rate of manufacturer will always increase. At the same time, the increase of carbon trading price will also promote carbon emission reduction. For the manufacturer, when the retailer remanufactures and pays fixed technology authorization fees, the manufacturer's profit is optimal. From this point of view, as a leader, the manufacturer will always choose the mode of retailer recycling and remanufacturing with fixed patent fees.
