Evolutionary game of platform enterprises, government and consumers in the context of digital economy
运用三方演化博弈理论分析政府、消费者与平台企业间的策略博弈，通过数值模拟发现加强监管和明确数据产权可改善市场秩序，而消费者和媒体的社会曝光能有效约束平台企业的歧视性定价行为。
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.
