Smart contracts, as an automatically executed programmatic protocol, offer new possibilities for economic transactions. This study explores the potential development path of smart contract technology supported by artificial intelligence to enhance the efficiency of economic transactions. A smart contract economic transaction model is constructed based on blockchain technology, and the feasibility and efficiency advantages of the model are verified by simulation analysis through Matlab R2020a calling Python program. The study used random function to generate economic transaction data, set the number of network nodes from 200 to 4000, and compared and analyzed the traditional economic transaction model and smart contract economic transaction model. The results show that the smart contract economic transaction model significantly reduces the transaction verification time compared with the traditional model, especially when the number of transaction subjects is huge, the efficiency advantage is significant. The path validation analysis shows that the transaction efficiency value of the economic transaction efficiency development path (D2) based on smart contract technology is consistently higher than that of the traditional path (D1), e.g., the transaction efficiency of D2 in the 20th set of data reaches 0.9939, while that of D1 is only 0.9620. The smart contract economic transaction model constructed by the research can effectively reduce the intermediary links, lower the transaction cost, improve the transparency of capital flow, optimize the experience of enterprise financial management through the two main development paths of payment process transparency and financial accounting intelligence, and provide technical support for the enhancement of the efficiency of economic transactions in the era of digital economy.
