Abstract: In recent years, with the rapid development of the Internet, especially the mobile Internet, enterprises use information technology to facilitate business acquisition, people through the Internet platform shopping and consumption, to provide great convenience for economic and social development, at the same time, due to the Internet-based market transactions on both sides of the information is asymmetric, resulting in the transaction between the two sides, in particular, manufacturers or distributors are more driven to increase the cost of the counterparty through the provision of false information, release of untruths and other means. At the same time, due to the asymmetry of information between the two parties in Internet-based market transactions, both parties, especially vendors and distributors, are driven to provide false information and publish inaccurate parameters in order to increase the counterparty’s costs. Aiming at the regulation of online non-honest market behaviours, this paper establishes a digital regulatory model “Digital Dynamic Game Regulatory Model for Online Non-Honest Behaviours” based on the basic principles of dynamic game and equilibrium theory. Specifically, this paper puts forward a generalised formal description framework for online dishonest practices, and then establishes a dynamic game regulatory model for “single merchant”, “multiple merchants” and “multiple merchants and multiple commodities” from simple to complex. A dynamic game regulatory model is then developed, and the process performance and strategy choices of each party in the dynamic game are discussed, providing a basic solution for the digital regulation of online dishonest behaviours.
