Research on the Influence of Subsidies on E-commerce Supply Chain Decision under the Background of Blockchain

Based on blockchain technology, this paper takes e-commerce supply chain decision-making as the research topic, and comprehensively considers many factors such as different consumer types, consumer traceability information, preference subsidy, etc., and constructs a business supply chain game model, and uses Stackelberg game theory to solve the equilibrium solution of the model. Finally, the results are verified by numerical simulation It is found that the use of blockchain technology can always make the profits of supply chain enterprises higher regardless of whether subsidies are made or not. With the increase of subsidies, the profits of supply chain enterprises will increase. For consumers, general consumers can always benefit from blockchain technology, loyal consumers need subsidies under certain conditions, but the same is true. The greater the subsidies, the more consumers will benefit from blockchain technology In addition, we find that subsidies can effectively improve social welfare, but there is a certain threshold beyond which the improvement effect will be weakened.
