In the green supply chain market,providing investment or loans to suppliers through re-tailers can reduce losses for retailers and the entire supply chain caused by insufficient supplier funds and inability to organize production normally.Under the scenario of random market demand,construct an internal equity financing and debt financing model of the supply chain with supplier funding constraints,analyze the optimal decisions of suppliers and retailers and their impact on them.Research has found that as consumer green preferences,retailer risk aversion,and profit distri-bution rates increase,product greenness and wholesale prices correspondingly increase;Under sup-plier funding constraints,whether through equity financing or debt financing,the greenness of the product will increase;Suppliers and retailers will choose different financing strategies to maximize their own interests.Only when the profit distribution rate is controlled within a certain range and eq-uity financing mode is implemented can both parties achieve maximum benefits.
