With the rapid development of shared mobility, third-party integrators have emerged recently to integrate competitive platforms that offer on-demand ride services in ride-sourcing markets. With platform integration, a passenger can request a ride through the integrator and can be matched with an idle driver affiliated to any of the integrated platforms, whichever is first or closer. As a result, passengers can access a higher level of supply, generating a thicker market with shorter average matching and pickup times. More importantly, platform integration maintains a competitive environment in which the participating platforms still set their prices, wages, and other operating strategies independently. In this talk, mathematical models are described to characterize the Nash equilibrium of the ride-sourcing market with multiple competing platforms and compare market outcomes with and without platform-integration. It is found that platform-integration can increase total realized demand and social welfare but may not necessarily generate a greater profit when vehicle supply is sufficiently large or/and market is too fragmented.
