Abstract: Taking the trend of growing network platform of cooperation between enterprises as the background,the paper analyzes the effect of the cooperation on the pricing strategy in the two-sided market.Under the assumption of bilateral multiple home users,considering the fact that inter-industry platform cooperation can improve the users’ intrinsic benefit,the study establishes a bilateral user multi homing duopoly competition model.Through the model, we can analyze the effect of enterprises participating in the cooperation and non-cooperation on the pricing, and further discusses what influences cross network externalities, platform differences and marginal cost have on the equilibrium pricing strategy. The paper indicates that with multi-homing users, the platforms tend to make strict symmetric strategy, which belongs to the symmetric equilibrium. Besides, the study also shows that cross network externalities, platform differences and marginal cost can have different influences on the platform depending on whether they participate in the cooperation.
