报告摘要：Two-sided service platforms, such as ride-hailing and food delivery, often engage in both demand- and supply-side competition. This competition can be either farsighted or myopic, depending on how the platforms anticipate the reactions of their rivals. Farsighted platforms consider the chains of reactions following their initial deviation and the long-term consequences of their actions, while myopic platforms only focus on the immediate payoff change of their one-step deviation. We study the farsighted stability in service competition between two on-demand service platforms and compare the stable outcome with the myopic one. We consider two scenarios: the platforms engage in demand-side competition only or in both demand- and supply-side competition. For the demand-side competition game, we find that the farsighted stable outcome coincides with the myopic one in ample- and moderate-size markets, but they differ in the scarce-size market. For the two-sided competition game, we find that farsighted platforms can coexist in the market with both earning a positive profit, while myopic platforms may lead to an equilibrium with zero profit for all. Farsighted platforms also tend to extract more surplus from both customers and workers than do myopic platforms. However, the platforms' farsighted behavior still falls short of achieving the optimal profit that a centralized system can attain.
