Balancing drone adoption with infrastructure readiness in China
The low-altitude economy is reshaping the future of aviation. Covering activities below 1,000 m, and extendable to 3,000 m, it integrates platforms from delivery drones to electric air taxis, marking a fundamental transformation in airspace use. In 2025, the total number of registered drones surpassed 3.28 million, with cumulative flight hours reaching 45.3 million, marking a nearly 70% year-on-year increase.1 The low-altitude economy ecosystem, as illustrated in Figure 1, encompasses an intricate network of unmanned aircraft, satellite-based communications and navigation, ground infrastructure, and urban airspace, all of which demand seamless coordination. To ensure safety and enable sustainable growth, China’s commitment is clear. In April 2024, the low-altitude economy was first mentioned in the government work report, a milestone widely recognized as “year one” of systematic development. In 2025, the “Government Work Report” emphasized promoting “safe and healthy development” of the low-altitude economy and conducting large-scale application demonstrations. In March 2026, the low-altitude economy was included in the Government Work Report for the third consecutive year, and its positioning was further upgraded to be among the four “emerging pillar industries” along with integrated circuits, aerospace, and biomedicine.
To fully realize this potential, several developmental challenges require systematic attention. The rapid expansion of low-altitude operations presents new management challenges that require evolutionary approaches to airspace systems designed for traditional civil aviation. Despite this, unmanned aerial vehicles (UAVs) continue to operate under regulations crafted for an era when low-altitude flights were rare and uniform, highlighting areas where regulatory frameworks require modernization to accommodate emerging technologies.
Managerial challenge
Traditional airspace management is designed for high-altitude operations above 6,000 m and for controlled terminal zones around airports, relatively structured environments characterized by standardized aircraft types, mature technologies, and well-defined separation rules. In contrast, low-altitude operations introduce a far more complex and dynamic environment. UAVs range from 250-g consumer drones to 2.4-ton passenger electric vertical take-off and landing (eVTOL) aircraft, flying through dense urban corridors, mountainous regions, and coastal areas, each presenting unique challenges in terrain, weather, and electromagnetic interference.2 Their operational objectives are diverse. For example, high-speed mission demands differ fundamentally from low-speed infrastructure inspections. As a result, traditional weight-based and mode-based separation rules, effective for conventional aviation, are no longer adequate for this heterogeneous and fast-evolving environment.
Coordination mechanisms
Low-altitude operations span multiple jurisdictions and require coordination among various government departments, from airworthiness certification and safety oversight to operational licensing and emergency response protocols. This multi-stakeholder environment represents a common challenge faced by aviation authorities worldwide as they adapt to emerging low-altitude activities. The National Airspace Management Committee serves as a coordination platform, facilitating dialogue between civil aviation authorities, military airspace management, and local government agencies. Crucially, to move beyond static administrative boundaries, this platform must facilitate dynamic airspace configuration, allowing algorithms to securely and swiftly reallocate airspace blocks based on real-time demand. As low-altitude activities expand from rural cargo operations to urban passenger transport, coordination mechanisms must accommodate varying risk profiles while maintaining system-wide coherence and efficiency.
