Abstract: We used differential game to study the coordination problem of supply chain, taking the digital transformation of the supply chain as the starting point, in which the knowledge accumulation of blockchain is the state variable. We solved and compared the quality improvement, blockchain technology investment, the trajectory of knowledge accumulation, market demand and supply chain profit in non-cooperative and cost-sharing scenarios. We also explored the blockchain technology in the supply chain from the perspective of game theory. Combined with numerical simulation, the sensitivity analysis of relevant parameters was carried out. The study found that the cooperation between players can improve the retailer's blockchain technology investment level without affecting the supplier's quality improvement strategy, effectively alleviate the “double marginal effect” of the non-cooperative case, achieve Pareto improvement of supply chain performance, and then improve the social welfare.

Key words: differential game, blockchain technology, knowledge accumulation, supply chain, digital transformation
