This paper considers consumers’data with economic value and privacy value in the two-sided market, analyzes the platforms’charging strategies, reveals the underlying mechanism and social welfare impact between data utilization and charging strategy. The results show that platforms always prefer a bilateral charging strategy that charges both consumers and sellers, but the bilateral charging strategy under the “acknowledge and agree” cannot achieve the highest social welfare. The “acknowledge and agree” affects the scale of data of platforms, which yields a higher charge towards sellers, and the social welfare under the unilateral charging strategy and the bilateral charging strategy remains the same. When both the quantity of the high-privacy-concern consumers and the data processing efficiency of platforms are high, the “acknowledge and agree” achieves the best or the second best of social welfare.
