Abstract：Under a carbon tax policy，this study explores how retailerscan optimize supply chain decisions through diferent 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 profitsare analyzed.Numerical simulations are employed to examine parameter sensitivity.The findings reveal that： An increase in carbon tax and areduction 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 allfour 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 monotonicallyunder other contracts;When the blockchain cost-sharing ratio fals below acertain threshold or exceeds it while carbon taxes surpassanother threshold，manufacturer profits are maximized underrevenue-sharing contracts.Insuch scenarios，product greennessretailer profits，and manufacturer profitsallreach optimal levels，making revenuesharing the most favorable contract choice.These research conclusions provide decision support for green supply chain to adopt blockchain technology.
