摘要：
As a vital component of the ride sharing area in the Chinese sharing economy, the “Internet + Green Transportation” new business form of sharing bikes plays a crucial role in resolving the citizens’ problem of “the last kilometer” and contributes greatly to alleviating traffic congestion and reducing air pollution in cities due to its convenience and environmental-friendliness. However, since bike sharing firms compete against each other to capture more market share by launching sharing bikes irrationally, there are excessive quantity of sharing bikes in some cities. Consequently, the excess of sharing bikes exacerbates the negative externalities created by riding sharing bikes, i.e., the adverse impact on the wellbeing of non-riders when riders ride sharing bikes. The government issues “Quantity Restriction Order” to resolve the problem of bike sharing excess. This paper constructs a theoretical model to analyse the mechanism of the government regulation on launching bike sharing. It shows that the government should consider the trade-off between the harm to non-users represented by the cost of negative externalities created by riding sharing bikes and the benefit to users represented by the user satisfaction when controlling the quantity of sharing bikes for different firms. This result indicates that the reasonable and effective “Quantity Restriction Order” on sharing bikes is not the one that controls the quantities of all firms’ sharing bikes but the one that controls the quantities of sharing bikes for different firms stage by stage. The result provides theoretical guidance for the government to solve and avoid the problem of sharing bike excess.
