Investment Rating - The report maintains a "Positive" investment rating for the industry [6]. Core Insights - The low-altitude economy is gaining momentum due to policy support, presenting significant development opportunities for the construction sector [4][62]. - The application scenarios for the low-altitude economy are rapidly diversifying, including emergency rescue, passenger transport, logistics delivery, agricultural production, surveying/planning, and intelligent inspection [17][24][26]. - The industry chain focuses on planning and infrastructure construction, with an emphasis on the manufacturing and service sectors related to low-altitude vehicles [32][50]. Summary by Sections Low-altitude Economy: Policy-Driven Development Opportunities - The low-altitude airspace generally refers to the vertical distance below 1,000 meters, which can be extended to 3,000 meters as needed. Recent policies aim to expand low-altitude airspace access and streamline management processes [4][13]. - The management reform of low-altitude airspace began in 2010, leading to a gradual relaxation of regulations and simplification of approval processes [14][15]. Application Scenarios: Rapidly Diversifying - Emergency Rescue: Drones can be used for disaster monitoring and efficient firefighting [17][18]. - Passenger Transport: Autonomous flying vehicles are expected to be widely used in urban air mobility, with significant market potential projected by 2040 [19][21]. - Logistics Delivery: Drones can significantly reduce delivery costs and improve efficiency, especially in remote areas [22][23]. - Agricultural Production: Drones are increasingly used in various agricultural applications, including pest control and crop monitoring [24][25]. - Surveying/Planning: Drones facilitate efficient data collection for land use and construction projects [26]. - Intelligent Inspection: Drones are utilized for real-time monitoring of infrastructure, enhancing inspection efficiency [28][29]. Industry Chain: Focus on Planning and Infrastructure - The manufacturing chain for drones and eVTOLs includes components such as structural parts, batteries, and flight control systems, which are crucial for the industry's growth [32][33]. - The service chain involves planning, engineering, and data services, with a focus on low-altitude airspace planning and infrastructure development [50][62]. - Ground infrastructure is essential for the low-altitude economy, including vertiports, emergency service stations, and logistics hubs [50][62].
