Abstract: E-commerce platforms, as the most dominant form of organization in the era of the digital economy, have developed rapidly, but also generated many negative problems. The rise and application of blockchain technology provides new ideas and methods for platform governance. Based on the technology embedding theory, this paper discusses the logic of blockchain technology-enabled platform governance from the two dimensions of “structure-function”. On this basis, an evolutionary game model of businessmen, consumers and platform enterprises is established. The implementation mechanism of blockchain-enabled platform governance is clarified by discussing the stability of the strategy and the evolutionary stability of the system, and the conclusions are verified by numerical simulation. The results show that in the process of blockchain technology-enabled platform governance, relying on the technological characteristics of blockchain can achieve a platform governance mechanism that “upholds the good and the truth while restraining the evil and the false in a moderate manner”. The initial intention of the three parties, the on-chain effect and the cost of regulation are important factors affecting the governance effectiveness of blockchain-enabled platforms, while merchant opportunistic behavior is the cause of platform dilemma. Therefore, this paper proposes to build a blockchain-based platform governance system, encourage merchants to use blockchain technology to improve the transparency and traceability of their own business, and guide consumers to participate in the construction of a blockchain online evaluation system, so as to promote the modernization, intelligence and efficiency of platform governance and high-quality development of e-commerce platform.
