Economic Value and Technological Synergy of Urban Low-Altitude Transportation Infrastructure: A Global Comparative Study

Abstract

With the rapid development of the low-altitude economy, urban low-altitude transportation infrastructure has become a key driver of urban economic growth and transportation system upgrading. This study explores the economic value and technological synergy mechanism of urban low-altitude transportation infrastructure through global comparative analysis. By examining 12 pilot cities in China, the United States, and the European Union, the research evaluates the economic impact of infrastructure construction from the perspectives of investment return, industrial agglomeration, and employment promotion. Meanwhile, it analyzes the integration and application of core technologies such as digital twin, 5G-A communication, and Beidou navigation in infrastructure operation. The results show that modular low-altitude take-off and landing facilities and intelligent air traffic management systems can improve airspace resource utilization by 25%-35% and reduce operational costs by 18%-22%. Policy suggestions are put forward to promote the sustainable development of low-altitude transportation infrastructure, including improving the hierarchical airspace management system and strengthening cross-regional technological cooperation. This study provides theoretical and practical references for the planning and construction of urban low-altitude transportation infrastructure worldwide.
