Abstract: As an important factor of production in the era of digital economy, data plays an increasingly important role in the operation of national economy. However, at this stage, China's social data is still in its infancy, so it is urgent to accelerate the data opening and sharing. In order to accurately analyze the data opening strategies of the government and the enterprises, the Nash non cooperative game, Stackelberg master-slave game and cooperative game models are constructed respectively by using differential game, and the optimal effort level, the optimal trajectory of social data opening level and the optimal return function of the government and the enterprises in three situations are obtained. Secondly, in the cooperative game situation, the time factor is introduced into Nash negotiation model to further analyze the dynamic income distribution mechanism with time consistency when the government and the enterprise cooperate. Finally,combining numerical simulation we analyze the sensitivity of related parameters. The research finds that when the proportion of government income distribution is more than 1/3, the revenue and social data opening level of Stackelberg master-slave game are higher than that of Nash non-cooperation; under the condition of cooperation, the total revenue and social data opening level of both sides can reach Pareto optimal state.
