Evolutionary game of platform enterprises, government and consumers in the context of digital economy

The game process of stable strategies among the government, consumers, and platform enterprises is analyzed by using tripartite evolutionary game theory. The evolution path of platform enterprise, government and consumers is analyzed through numerical simulation by introducing parameters such as the degree of discriminatory pricing, the degree of data property right confirmation, and the intensity of supervision. Results show that the government can improve the market order by strengthening supervision and defining data property rights. When the benefits is higher than the punishment cost, the platform enterprises will choose to discriminatory pricing. But consumers and the media can effectively restrain the discriminatory behavior of platform enterprises by social exposure. In addition, in the face of discriminatory pricing on the platform and lax government supervision, consumers who are vulnerable can only "vote with their feet", and their personal rights and supervision rights are difficult to protected.
