Contribution of shared bikes to carbon dioxide emission reduction and the economy in Beijing

In recent years, the popularity of sharing economy has been growing worldwide. Therefore, its features must be understood to adapt the economic development for the enterprises. The performance of Mobike in Beijing is used as a case in this study. Mobike is the largest shared bike company in the world and plays a prominent role in the sharing economy. Based on data obtained, online reports, and actual situations, the factors affecting the environment from shared bikes and the usage of bikes have been analyzed qualitatively and quantitatively. From the qualitative analysis, the model of the contribution of carbon dioxide emission reduction to the society has been constructed with the significant variables of registered rate, riding distance, and usage rate for shared bikes. The influence degree of each variable and their interactions are evaluated through response surface method and Minitab. The influencing extent of factors on CO2 emission reduction is in the following order: riding distance > proportion of registered users > usage rate of shared bikes. The results show that shared bike plays comprehensive and positive roles for economy and environment. The study will provide a significant help for policymakers and business supervisors on development of shared bikes.
