基于政府补贴的双渠道绿色供应链决策研究

Research on Dual-channel Green Supply Chain Decision-Making based on Government Subsidies

文章构建由单一制造商和零售商组成的双渠道绿色供应链,考虑政府实施绿色研发创新补贴政策,运用博弈理论求解分散决策和集中决策两种情形下双渠道绿色供应链的最优决策,并分析比较不同情形下最优决策的变化,研究了政府补贴系数对各项最优决策的影响,并通过数值算例分析证明了结果的准确性。研究表明:集中决策下双渠道绿色供应链的最优决策均会优于分散决策下,供应链成员进行合作更有利于双渠道绿色供应链的长期发展;政府实施绿色创新研发补贴能够提升供应链的绿色度,改善供应链成员的利润。

By establishing a dual-channel green supply chain consisting of a single manufacturer and a retailer,and considering government subsidies for green R&D and innovation,this paper resolves the optimal decisions of the dual-channel green supply chain under decentralized and centralized decision-making scenarios using the game theory.Moreover,this paper analyzes and compares the changes of optimal decisions in different scenarios,examines the effects of government subsidy coefficients on the optimal decisions,and demonstrates the accuracy of the results through numerical example analysis.The research results shows that the optimal decisions of dual-channel green supply chain under centralized decision-making are superior to those under decentralized decision-making,and the cooperation of supply chain members is more conducive to the long-term development of dual-channel green supply chain.Moreover,government subsidies for green innovation and R&D can facilitate the green development of the supply chain,and improve the profitability of supply chain members.
