Abstract: In the context of a dual-channel supply chain,based on the uncertainty of consumers' green preferences and the volatility of product green levels,considering the risk preferences of members,introduce the time factor,the differential game was used to solve the optimal strategy of the dynamic dual-channel green product supply chain under four different risk preferences decisions.The research showed that manufacturers' investment in green products was positively correlated with consumers' green preferences and negatively correlated with offline sales loyalty;product green levels,manufacturer's sales prices and total supply chain utility under centralized decision-making were higher than decentralized decision-making,but the retailer sales price was lower than decentralized decision;wholesale price,product green level and manufacturer's sales price were the highest under the retailer's risk aversion decision,and the lowest under the manufacturer's risk aversion decision,while the retailer's sales price was the highest under the risk-neutral decision,and the lowest under the manufacturer's risk aversion decision,the opposing member's risk aversion behavior was beneficial to themselves.
