Abstract: The low-altitude economy is a strategic emerging industry and representative of new quality productive forces. Against the backdrop of accelerated deployment across regions, how to efficiently empower economic formats is a topic worthy of study. The deep integration of the low-altitude economy with aviation-based foreign trade, and the construction of an integrated low-altitude and high-altitude air transport model, are important pathways that align with the national strategic positioning of low-altitude economic development and the demand for high-quality development of aviation foreign trade. Integrated low-altitude and high-altitude transport, both belonging to air transport, can achieve airspace coordination, share traded goods, talent, maintenance services, and port customs clearance facilities, and foster related industries, thus generating scale synergies-especially beneficial for inland regions engaging in foreign trade. However, such integration currently faces challenges such as route conflicts, inadequate facility compatibility, lack of regulatory standards, and limited coverage of international routes and scenarios. To promote foreign trade development through integrated low-altitude and high-altitude air transport, effective measures can be adopted: encourage competent authorities to establish a three-dimensional aviation concept, and develop unified integrated transport standards; support carriers in designing integrated route networks and coordinate night-time transport; permit shared use of infrastructure and expand integrated transport scenarios; and stimulate enterprises to participate in integrated transport and encourage inter-firm cooperation.
