In the bike-sharing ecosystem, various groups are in the information asymmetry condition. The pursuit of interests maximization causes long-term continuous game status. The three main populations of the bike-sharing ecosystem are taken as the game subjects, and the dynamic evolutionary game model and replication dynamic equation of the three-party cooperative symbiosis under the assumption of bounded rationality and information asymmetry are established by using the game theory. It is found that the main factor affecting the stable evolution of the bike-sharing ecosystem was the rate of return of cooperation strategy. The probability of the bike-sharing ecosystem tending to the cooperative state was proportional to the rate of return of cooperation strategy.
