Research on supply chain collaboration carbon emission reduction strategies embedded in a blockchain under cost-sharing contracts

Key Points

This research aims to explore how blockchain technology and cost-sharing contracts can reduce carbon emissions in a supply chain.
Constructed a two-level low-carbon supply chain model including a manufacturer and retailer.
Embedded blockchain technology within a traditional cost-sharing incentive contract framework.
Developed a game model considering consumer green trust and low-carbon preferences.
Conducted calculations to evaluate the effects on carbon emission reductions and corporate profits.
Adoption of blockchain can enhance supply chain efficiency while potentially lowering retailer profits.
When blockchain costs are below a certain threshold, adoption effectively boosts carbon reduction rates.
Improved green trust among consumers leads to a larger market for low-carbon products.
Overall supply chain profits can increase when cost-sharing mechanisms are effectively implemented.

Abstract

We construct a two-level, low-carbon supply chain comprising a manufacturer and retailer. Under the incentive contract model of traditional cost sharing, blockchain technology is embedded, and a game model is established considering the influence of consumers' green trust and low-carbon preference coefficient. Through calculations, this study examines the impact of manufacturers adopting blockchain technology and retailers cooperating with suppliers to reduce carbon emissions through cost sharing on the carbon emission reduction rate and corporate profits. This study finds that if blockchain technology is adopted, retailers' sharing of carbon emission reduction costs can improve supply chain efficiency but reduce retailers' profits. When the costs of blockchain technology are below a certain threshold, its adoption can effectively improve the carbon emission reduction rate, win the green trust of consumers, expand the market for green and low-carbon products, and improve the profits of the supply chain.
