In the field of logistics, drones have sparked an efficiency revolution - they can provide precise point-to-point delivery, overcome ground transportation obstacles, and significantly shorten delivery time; In agricultural production, drones combined with AI visual recognition systems and other technologies can monitor crop growth in real time and assist in scientific planting... Air taxis are also becoming a reality - electric vertical takeoff and landing aircraft integrating high-performance batteries, carbon fiber materials, AI flight control and other technologies have made significant progress. The "air taxi" from Shenzhen to Zhuhai has shortened the one-way ground travel time from about 3 hours to 20 minutes. These applications have a common name - low altitude economy. Generally speaking, the low altitude economy relies on the low altitude airspace (usually below 1000 meters, and some scenarios can be extended to 3000 meters) as the core, and constructs a full chain industrial system covering manufacturing, flight, and service through manned or unmanned aerial vehicles. It is deeply integrated with traditional fields such as agriculture, logistics, and tourism, forming a three-dimensional economic ecology of sky and ground. Low altitude economy is the intersection of technological innovation and institutional change in the digital age, reshaping the modern industrial landscape with its unique "three-dimensional economy" attribute. As a new highland of national strategic science and technology, the low altitude economy is based on the general aviation industry, integrating emerging technologies such as unmanned aerial vehicles, electric vertical takeoff and landing vehicles (eVTOL), and integrated information networks of air, space, and earth, gradually reconstructing the way humans use space. From a strategic perspective, the low altitude economy has significant value in expanding a country's development space and cultivating new quality productive forces. Its level of development has become a new dimension for measuring a country's technological competitiveness. In the development of low altitude economy and technology, major economies around the world have formed differentiated paths with technological innovation as the core. The UK has relaxed restrictions on drone flights in cities, allowing for drone beyond line of sight testing; Countries such as the United States, Germany, and Japan are conducting research on air traffic operations and management to promote their integration with smart cities... At the same time, countries attach great importance to government enterprise cooperation, increasing investment in infrastructure such as vertical takeoff and landing airports and air traffic management, expanding application scenarios such as urban travel, agricultural logistics, emergency rescue, etc. Through financial support, talent cultivation, and global cooperation, they are promoting the research and development of low altitude economic technologies and industrial scale. In recent years, China has emerged as a rising star in the field of low altitude economy, becoming an important force in the global development of low altitude economy and achieving rapid growth. The "low altitude economy" was first included in the national plan in 2021, listed as a strategic emerging industry in 2023, and included in the "Government Work Report" in 2024. The Third Plenary Session of the 20th Central Committee of the Communist Party of China explicitly proposed the development of general aviation and low altitude economy. The Central Air Traffic Control Commission has issued special measures, focusing on improving the low altitude management system, optimizing the allocation of airspace resources, enhancing the quality and efficiency of operational services, consolidating basic support capabilities, and strengthening the legal management of air use. These measures will be deployed to the national air traffic control system to strengthen low altitude air traffic control work. A series of top-level designs, local pilot projects, and industrial implementation paths have demonstrated institutional advantages in emerging technology fields. Behind the vigorous development of China's low altitude economy is a powerful support for technological progress. In the field of aircraft manufacturing, China's independently developed new carbon fiber composite materials have outstanding advantages such as light weight, high strength, and strong stiffness, and are widely used in various types of aircraft, further improving endurance and load capacity. In terms of power systems, China is striving to promote the mass production of 400Wh/kg aviation lithium battery products, and in the future, achieve the application verification of 500Wh/kg aviation lithium battery products, providing solid support for the development of urban air traffic. Communication and navigation technology are also contributing to the low altitude economy. The Beidou satellite navigation system, independently built by our country, has a positioning accuracy of centimeter level. Coupled with the 5G-A low altitude communication network, it enables unmanned aerial vehicles to fly accurately and collaborate in complex environments. In logistics and distribution scenarios, drones rely on these technologies to achieve efficient distribution between urban commercial districts and communities. Artificial intelligence technology has equipped the low altitude economy with a smart 'brain'. The AI visual recognition system enables drones to accurately identify pest and disease areas in agricultural crop protection, carry out targeted operations, and effectively improve agricultural production efficiency. In terms of low altitude traffic management, intelligent algorithms can optimize flight routes in real time, allocate airspace resources reasonably, alleviate airspace congestion, and ensure flight safety. New technologies give rise to new economic forms, which require corresponding new rules, policies, and laws. In the development of the low altitude economy, there are currently some policy and legal issues. For example, the airworthiness certification cycle is relatively long, and some aircraft require up to 18 months for airworthiness certification, which to some extent delays the speed of new products entering the market. At the same time, the airspace management standards in different regions are not yet unified, and there are differences in airspace division, flight approval processes, and other aspects among different regions, which brings inconvenience to low altitude flight activities across regions. Our country has taken note of this issue. In recent years, efforts have been continuously made to construct a policy system for the low altitude economy, gradually advancing from top-level design at the national level to local practice, and safeguarding the development of the low altitude economy. On January 1, 2024, the Provisional Regulations on the Flight Management of Unmanned Aerial Vehicles were officially implemented, which comprehensively regulates the design, production, and operation of the unmanned aerial vehicle industry. In addition, local governments have introduced relevant policies and actively laid out low altitude economic industries. As of the end of 2024, Shenzhen has opened 250 drone routes and built 483 low altitude takeoff and landing points, leading the country in low altitude economic practice. Shenzhen has gradually built a distinctive low altitude economic industry ecosystem through measures such as legislation, financial support, and pilot airspace opening. Guangzhou is also making every effort to promote the development of low altitude economy, and the "Guangzhou Low altitude Economy Development Regulations" will be officially implemented on February 28, 2025. The regulation explicitly strengthens communication and coordination with air traffic management agencies and civil aviation management departments, establishes a multi-party collaborative management mechanism, and clarifies the division of responsibilities among various departments. In terms of infrastructure construction, support the construction of low altitude flight service stations, city level low altitude flight comprehensive management service platforms, and explore the establishment of a low altitude airspace classification and flexible deployment mechanism. Low altitude economy is becoming a new blue ocean. The Civil Aviation Administration of China predicts that the market size of China's low altitude economy will reach 1.5 trillion yuan by 2025 and is expected to reach 3.5 trillion yuan by 2035. In the future, innovation in low altitude economy fields such as battery technology, communication technology, AI technology, etc. will show a trend of diversification and integration. The ultimate competition in the low altitude economy has never been limited to the hardware game of aircraft, but also the coordinated development of materials science, communication technology, and intelligent algorithms in three-dimensional space. Only by allowing technological genes to penetrate the industrial texture can we unlock new possibilities for the symbiosis between the sky and the earth. (New Society)
