Recently, the "2025 IET Management Symposium: Innovation in Low-Altitude Economy and New Development Prospects for Hong Kong", hosted by the Institution of Engineering and Technology (IET), commenced at Hong Kong Science Park. As a core think tank for smart transportation in the Greater Bay Area, the SUTPC Digital Technology (Hong Kong) Limited – the international headquarters of Shenzhen Urban Transport Planning Center Co., Ltd. (hereinafter referred to as "SUTPC") – was invited to attend. It systematically put forward the "Sky-Road Interconnection · Shenzhen-Hong Kong Integration" development concept for the low-altitude economy for the first time, attracting widespread attention from government agencies, international enterprises, and academic representatives.

The low-altitude economy has become a new strategic competition track for major global economies. In the Guangdong-Hong Kong-Macau Greater Bay Area, Shenzhen, with over 1,700 drone enterprises, a "1+N" low-altitude regulatory system, and a civil unmanned aviation test zone, has built a complete industrial chain covering R&D, manufacturing, and scenario applications. Hong Kong, leveraging its advantages as an international aviation hub, free port policies, and "regulatory sandbox" mechanism, focuses on application scenarios such as drone transportation and eVTOL commuting, aiming to become a core node for the coordinated development of the low-altitude economy in the Greater Bay Area.

SUTPC's independently developed low-altitude digital management and operation platform, based on the city-wide digital twin TransPaaS platform, integrates four innovative capabilities to build a full-link intelligent solution for the Shenzhen-Hong Kong cross-border low-altitude corridor. With high-precision digital twin as the foundation, the platform establishes a low-altitude management and service system covering four modules including airspace planning and route management. For the government, it can process real-time flight data of over 100,000 concurrent in-air aircraft, enabling trajectory simulation, behavior prediction, intelligent conflict resolution, and scheduling optimization. For enterprises, it integrates service management functions such as route approval and flight activity declaration, promoting the large-scale implementation and development of the low-altitude economy.

This symposium brought together global experts, scholars, government officials, and business leaders in the low-altitude economy field, focusing on the development and opportunities of Hong Kong's low-altitude economy, and discussing topics such as future urban air mobility, cross-industry cooperation potential, and the transformation path of low-altitude smart cities. SUTPC's "Sky-Road Interconnection · Shenzhen-Hong Kong Integration" concept and its implementation path explored how to build a low-altitude economy corridor in the Greater Bay Area through digital sky roads, providing a clear technical roadmap and cooperation framework for Hong Kong and the Greater Bay Area to seize new opportunities in the low-altitude economy. Currently, SUTPC is leading two Hong Kong regulatory sandbox projects: a structured low-altitude infrastructure device (Micro-Airport) integrating aircraft navigation, surveillance, takeoff/landing, and operation and maintenance functions, and a Shenzhen-Hong Kong low-altitude digital logistics customs clearance project. It is expected to collaborate with all parties in the future to promote coordinated innovation in the low-altitude economy based on low-altitude digital infrastructure, facilitate the integrated development of low-altitude logistics, transportation, and regulation, and inject new momentum into the low-altitude industry ecosystem in the Greater Bay Area.
