Abstract:With the opening of low-altitude airspace, UAVs have been rapidly developed and applied. Vigorously promoting urban air mobility (UAM)can provide a new direction for the construction and development of smart cities in the future. This paper introduces the theory of innovative ecosystem to explore how the UAM system develops. The results show that the UAM innovation ecosystem consists of ‘chnology-application-business’ main body system and environmental system. Driven by the policy-leading mechanism, technology-driven mechanism, scenario-driven mechanism and financial support mechanism, suggestions are put forward from the levels of government, technology and application scenarios to promote the sustainable development of the UAM innovation ecosystem. The conclusion is helpful to the future development of UAM, improve the industrial ecology and business model innovation of enterprises.
