Abstract: With the popularization of public sports service as well as the rapid development of digital economy, the smart service of public sports has become the major trend in the new era. The external network, platform-driven technology and the openness and synergy, characterized by platform economy, effectively respond to the lag of the supply-side reform of public sports service, and overcome the identification dilemma from the public as well as the performance dilemma from public sports workers. On this basis, with the help of platform-driven data integration and sharing, interest led and function coordination, a chain operation mechanism is formed to promote the accurate identification of public needs, the joint participation of multiple bodies and the in-depth integration of sports resources. In the future, the platform-driven model needs the effective guidance of the government, which can be started from the aspects of establishing platform regulation codes, promoting the platform to "turn private into public" and correcting the narrowness of technology, etc.
