The fairness concern is introduced into a closed-loop supply chain system with a dominant retailer. Under the case that considering and without considering the dominant retailer's fairness concern, the optimal decisions of members as well as the whole closed-loop supply chain system are analyzed respectively, and the equilibrium results are compared. The results show that the dominant retailer's fairness concern is beneficial to the maximization of his own utility, but unfavorable to the profit maximization of the manufacturer and the third party recycler. The increase of dominant retailer's fairness concern is unfavorable to the utility of the whole closed-loop supply chain system when the fairness concern is relatively weak, but it will be beneficial on the contrary.
