Abstract:Low-altitude airspace is a resource that needs to be fully explored, and the low-altitude economy is a new type of economic activity resulted from low-altitude airspace exploration and utilization. As the primary players of low-altitude flight activities, the commercialization and wide applications of unmanned aerial vehicles (UAVs) are promoting the prosperity of the low-altitude economy. A low-altitude air route network is an effective means to ensure the safe and efficient operations of a large number of UAVs, and it is also a new key infrastructure hosting low-altitude traffic. The history shows that the investment on public transport infrastructure as a policy tool to help economic growth has been widely used; similarly, investment on and construction of the lowaltitude air route network infrastructure will yield significant social and economic benefits and foster a landscape rise of the lowaltitude economy. Addressing the current issues of vague definitions and development paths in the low-altitude economy, this study attempts to propose a technical solution from the perspectives of geography science by constructing low-altitude air route network infrastructure and an airspace revenue mechanism to unlock the potential of the low-altitude economy.
