Study on CSR input of two-cycle supply chain under cost learning effect
Based on the cost learning effect of manufacturers,a two-cycle supply chain system consisting of a single manufacturer and a single retailer is constructed.Stackelberg game theory is used to study the impact of retailer corporate social responsibility(CSR)investment cycle on supply chain decision-making,and to ex-plore the choice of retailer CSR investment mode.The research shows that:for the whole supply chain,retailer's CSR investment is always beneficial.When CSR is invested in both phases,manufacturer and retailer's profit maximizes.The profit of manufacturer and retailer increases with the increase of cost learning effect.Cost learn-ing effect and consumer CSR preference weaken the impact of price on profit.The decentralized decision-making model will cause efficiency loss due to double marginalization.Pareto improvement can be achieved through the joint revenue-cost-sharing contract and two-part pricing contract,and the supply chain profit can reach the profit under centralized decision.Finally,an example is given to verify the validity of the relevant conclusions.
