The Mobility-as-a-service (MaaS) market worldwide is expected to reach a market capitalization of about 9.5 trillion U.S. dollars by 2030. This immense growth is fueled by the growing ride-sharing, e-hailing, and carsharing service industries as well as bikesharing programs across the globe. Meanwhile, the market size of MaaS in China stood at 15 billion U.S. dollar as of 2017, and is forecasted to soar to over 200 billion U.S. dollars by 2025 and eventually till over 650 billion by 2030. Currently, the traditional mobility industry is still much bigger than the shared mobility market size in China, where car-hailing accounted for the largest share of the market compared to car-pooling and car-sharing.
Didi chuxing, the Chinese version of Uber, started providing ride-hailing service since 2012 and eventually acquired the Uber Chinese subsidary in 2016. Didi has become the leading player in the market, with hundred times more daily order than the other car-hailing apps in China, like Meituan or Caocao. Within this segment of car-hailing, over half of the transaction volume took place in first tier cities, and most of the rest happened in second tier cities.
