| This paper considers using blockchain to solve the problem of information opacity in a secondary clothing supply chain network composed of one supplier and one retailer. Building stackelberg game model considering some factors as retailers' sensitivity to information sharing and the application degree of blockchain. The model explores the impact of blockchain on members of the clothing supply chain and the optimal conditions if introduce blockchain. Then, it analyzes the optimal decision-making under different government subsidies. The research shows that: under the condition of only using blockchain technology without government subsidies, the introduction of blockchain technology will not be considered, as the introduction of blockchain technology reduces supplier profits and increases retailer profits. Retailers hold a supportive attitude towards the introduction of blockchain technology, while suppliers will not cooperate due to damaged interests; Under the conditions of adopting blockchain technology and government subsidies, the introduction of blockchain technology will be considered, because the government will adopt two subsidy methods to optimize the profits of supply chain members in order to enhance the willingness of suppliers to join blockchain technology and promote its application. If fiscal subsidies are used and the subsidy amount is large enough, or if tax exemptions are used and blockchain usage is high, the profits of suppliers and retailers will increase, Both will support the introduction of blockchain technology; The adoption of tax reduction is more conducive to the overall supply chain environment, because when fiscal subsidies are used, the pricing of supply chain members is not affected by the subsidy amount, and the subsidy amount only affects the profits of supply chain members. When tax reduction is adopted, retail prices decrease, which is more beneficial to consumers and increases market demand. |
