Closed-loop Supply Chain Model Analysis of Home Appliances based on Promotional Effort and Recycling Effort

Abstract

Nowadays, a large number of home appliances have entered the node of renewal, if they can be properly disposed of and utilised, used home appliances can also be converted into renewable resources to achieve the economic cycle, and at the same time, green living and circular economy are increasingly accepted by the public. Recycling of used home appliances has both economic and social benefits. At the same time, promotional efforts invested in the market for home appliances have an obvious effect on increasing their market demand. Therefore, it is necessary to study the closed-loop supply chain of home appliances based on promotion and recycling efforts. In this paper, we use literature analysis, mathematical analysis and Stackelberg game analysis to construct a closed-loop supply chain model for home appliances based on promotional and recycling efforts after determining who is the promoter among manufacturers and retailers, and then compare and analyse the decisions and benefits of the supply chain members, taking into account their centralised and decentralised decision-making. The results of this paper show that: (1) when home appliance manufacturers, retailers and third-party recyclers of used home appliances make decentralised decisions, there is a double marginal effect, i.e., the supply chain members only consider their own benefits while ignoring the benefits of the supply chain as a whole, which results in the failure of this closed-loop supply chain system of home appliances to be coordinated. (2) When the retailer's promotional effort is greater, both the retail price and the retailer's profit are lower. (3) The greater the recycling effort of the third-party recycler of used home appliance products, the higher its recycling price, i.e., the consequent increase in recycling costs, leading to a decrease in its profit.
