Abstract

In the era of economic globalization, product trading markets are strongly impacted. The comprehensive utilization of e-waste is an important way to integrate green supply chains and improve resource utilization efficiency. Based on retailers and e-commerce platforms as mobile phone recycling entities, this paper constructs a dual-channel green supply chain dynamic game model and examines the impact of the trade-in strategy on the integration of the green supply chain. The results show that offset price, recovery price, and recovery quantity are positively correlated with the income through their respective channels. The transfer payment price is positively correlated with the revenue of the two channels. Trade-in strategy will increase the offset price, recovery price, and manufacturers’ profits. However, the profits of retailers and e-commerce platforms are affected by the substitutability coefficient between channels and the sensitivity of recovery price. The optimal equilibrium in the supply chain is conducive to integrate waste mobile phone green supply chain, effectively cope with the impact on the global mobile phone manufacturing supply chain, and promote the realization of the “dual carbon” goal.
