摘　　要：在碳配额与交易监管下,基于Nash非合作博弈与变分不等式理论,考虑碳排放权初始分配环节中供应商存在谎报碳配额行为与绿色信息敏感型消费者对产品核实需求,构建应用与未应用区块链技术的2种平台供应链网络均衡模型,对比研究应用区块链技术前后各平台供应链成员的均衡决策及区块链应用阈值。利用修正收缩投影算法对模型进行求解,并通过数值算例可得:应用区块链技术可避免碳交易量不一致的情况,进一步减少资源的浪费并提高供应链利润;供应商谎报碳配额的行为在一定程度上能提高供应链整体利润,但抑制了供应链获得更高利润的能力;在一定的区块链运营成本阈值内,供应链成员才有采用区块链技术的动机。Under the cap-and-trade regulation,based on Nash non-cooperative game theory and variational inequality theory,considering supplier's misrepresentation of carbon caps during the initial allocation and the demand of green information sensitive consumers for product verification,two platform supply chain network equilibrium models with and without blockchain technology are constructed.Then this paper explores and compares the equilibrium conditions of supply chain members and blockchain technology application thresholds before and after the application of blockchain technology.The modified contraction projection algorithm is used to solve the problem and some numerical examples are given to show that:the application of blockchain technology can avoid the inconsistency of carbon emission trading volume,further reduce the waste of resources and improve the profit of the supply chain.The supplier's misrepresentation of the carbon cap can to some extent improve the overall profit of the supply chain,but it inhibits the ability of the supply chain to achieve higher profits.Within a certain threshold of blockchain technology operating costs,supply chain members have the motivation to adopt blockchain technology.
