Abstract:Considering the closed-loop supply chain pricing and recycling decision problem of new energy vehicles under blockchain technology, a Stackelberg game model was constructed for the on-chain members under the recycling modes of manufacturers and retailers. The results show that as consumers' preference for green products increases, carbon emission reduction efforts, profits of chain members, and social welfare increase. Increasing the proportion of laddered utilization will increase retailers' profits under the retailer recycling mode, manufacturers' profits under the two recycling modes, and social welfare, and in particular, the introduction of blockchain and manufacturers' recycling has a significant impact on social welfare. Adopting blockchain is conducive to increasing the quantity of demand and carbon emission reduction efforts when the unit cost of blockchain adoption meets a certain threshold value.
