Evolutionary game of banks and enterprises in digital supply chain finance driven by blockchain

In order to explore the influence of blockchain technology on supply chain financing, this article builds an evolutionary game model of banks and enterprises, which is associated with traditional supply chain finance financing and digital supply chain finance based on blockchain technology, besides, the article also analyzes the evolutionary path of subject behavior in different situations. Our research shows that, both of the two evolutionary game models have three stable evolutionary states. Through simulation, we find that under the guarantee of blockchain technology, the role of punishment mechanism and credit incentive can be better played in supply chain financing, and the supply chain ecology will be more optimized.
