Research on the Collaborative Regulation Mechanism of Big Data-Enabled Price Discrimination against Existing Customers in the Quantum Entanglement State

The quantum cognition and decision method can solve the sequential effect and interference effect caused by the state superposition of a large amount of uncertain cognitive information in the process of coregulation of big data "killing" behavior, and develop a reasonable strategy. The game model is constructed from the perspective of the co-regulation of the government and the e-commerce platform, and the final strategy choice is based on the co-regulation strategy of both bodies. The quantum entanglement theory is used to explain the perfect regulation and perfect non-regulation modes in the strategy choice in the quantum entanglement state. The results show that the inherent mechanism of coregulation has quantum properties based on the government and the e-commerce platform; the regulation effect is better after considering the quantum entanglement state, which can solve the free rider problem in the process of co-regulation to a certain extent; The entanglement contract can ensure that the benefits of both bodies are related to their own efforts to achieve the optimal incentive effect.
