Since the green level of products is affected by the manufacturers'green investment intention,supply chain members begin to consider risk aversion behavior in the supply chain.Using the dual-channel green supply chain with risk aversion behavior model analyzes centralized and decentralized dual-channel decisions.And finally,through the two-part pricing cost-sharing contract,members are co-ordinated.The results are verified by numerical analysis.The research shows that:When online sales volume is high,manufacturers'green investment efforts are relevant to consumers'green preference,manufacturer's tolerance,and retailer's tolerance under coordination contracts,and negatively correlated with retailer's tolerance under decentralized decision-making;product green level,manufacturer's green investment effort,manufacturer's selling price,and total system profit under centralized decision-making are higher than those under decentralized decision-making,while retailer's selling price is lower than that under decentralized decision-making;when the cost-sharing ratio and the fixed cost meet certain conditions,the two-part pricing cost-sharing contract can perfectly coordinate the supply chain.
