碳税政策下考虑区块链技术的绿色供应链最优契约
Optimal contracts for green supply chains considering blockchain technology under carbon tax policies
摘要
Abstract
Under a carbon tax policy,this study explores how retailers can optimize supply chain decisions through different incentive contracts when manufacturers invest in both green product R&D and blockchain technology.Using Stackelberg game theory,the optimal decisions for each contract are derived,and the differences in product greenness,pricing,and profits are analyzed.Numerical simulations are employed to examine parameter sensitivity.The findings reveal that:An increase in carbon tax and a reduction in blockchain cost both encourage manufacturers to increase green R&D investment,with the highest product greenness achieved under the revenue-sharing contract;Retailer profits under all four contracts first decrease and then increase with rising carbon taxes,peaking under the revenue-sharing contract;Manufacturer profits demonstrate a U-shaped relationship with carbon taxes under revenue-sharing contracts but decline monotonically under other contracts;When the blockchain cost-sharing ratio falls below a certain threshold or exceeds it while carbon taxes surpass another threshold,manufacturer profits are maximized under revenue-sharing contracts.In such scenarios,product greenness,retailer profits,and manufacturer profits all reach optimal levels,making revenue-sharing the most favorable contract choice.These research conclusions provide decision support for green supply chain to adopt blockchain technology.关键词
