Abstract: To solve the problem of mistrust in the recycling process of green products,the Stackelberg game was used to compare and analyze the impact of manufacturers' adoption of blockchain,retailers' recycling and third-party recycling on the pricing decision of green supply chain by introducing the parameters such as the weakening factors of consumers' trust in the source of green products,the traceability level of manufacturers on products,and the discount factor of recycling quantity.The research showed that the green degree of products,the recovery rate of waste products and the profits of members would be improved through reducing weakening factors of consumers' trust in the source of green products or improving consumers' sensitivity to the traceability level of products;although the retail price of products would be increased with the unit verification fee for recycling waste products,the product traceability level of manufacturers,the recycling rate of waste products and the profits of members would be reduced;the retailer recycling could maximize the profits of each member whether the manufacturer adopted blockchain or not;when the weakening factors of consumers' trust in the source of green products and the consumers' sensitivity to the traceability level of products met a certain threshold,the use of blockchain could enable supply chain members to obtain more profits.
