As the core support for the safe operation and commercial ecosystem of the low-altitude economy

low-altitude infrastructure remains a bottleneck in the industrial chain. Its development faces technological bottlenecks

structural contradictions

and institutional constraints

which hinder the scaled growth of the low-altitude economy. In response

this study focuses on three types of capital-intensive infrastructure: low-altitude communication

surveillance

and takeoff/landing facilities. It reviews their current status and operational requirements

analyzes three deep-seated structural contradictions restricting the scaled development of the low-altitude economy

and proposes targeted solutions. The research aims to provide theoretical and practical insights for advancing the large-scale construction of low-altitude infrastructure and promoting the high-quality

scaled development of the low-altitude economy.
