Integrated supply chains propel Greater Bay Area's low-altitude economy growth

The Guangdong–Hong Kong–Macao Greater Bay Area (GBA) is emerging as a key engine for China's fast-growing low-altitude economy by leveraging its dense industrial networks, efficient logistics systems, and rapid innovation capacity.

From logistics and manufacturing to urban services, the region is building an integrated industrial chain that allows low-altitude industries to scale up at unprecedented speed, thus turning drone-based applications from isolated trials into large-scale, commercial operations.

China's 15th Five-Year Plan, covering 2026 to 2030, calls for the cultivation of new pillar industries and the accelerated development of strategic emerging industrial clusters, including the low-altitude economy.

At a drone operations center in Bao'an District, Shenzhen City in south China's Guangdong Province, a dozen logistics drones take off and land within minutes. Urgently needed production parts, documents, and small parcels are dispatched from here to cities in the province including Dongguan, Zhongshan, and Zhuhai.

Behind these high-flying aircraft lies what observers describe as an "invisible industrial chain", built on speed and efficiency.

"Look at this aircraft. About 90 percent of its components come from nearby areas. Relying on Shenzhen's strong logistics capabilities and its complete supply chain, these parts can be delivered to our factory within half an hour for assembly, processing, and production," said Li Kunhuang, person-in-charge of Shenzhen GODO Innovation Technology Co., Ltd.

Once a new product is unveiled, testing and calibration begin immediately at the drone testing field. As soon as the process is completed, the new models can be put into real-world operation, realizing almost “zero delay” from research and development to application.

Supported by a robust industrial chain, low-altitude routes in Shenzhen are effectively connecting the urban landscape. From its Bao'an District to Songshan Lake in Dongguan City, production components can be delivered within one hour. Supplies are transported between Zhuhai City's Xiangzhou Port to Dong'ao Island in just 25 minutes. And light industrial goods can travel round-trip within a single day between Guzhen Town in Zhongshan City and Xinhui District in Jiangmen City.

More low-altitude application scenarios are expected to be implemented in the near future.

In Qianhai District, Shenzhen is accelerating the construction of a pilot demonstration zone of low-altitude integrated three-dimensional transportation hub.

"We have built the country's first low-altitude integrated three-dimensional transportation hub, and are gradually developing a pilot flight zone that integrates multiple scenarios such as inspection, logistics, and cultural tourism. This will provide technical support for the next step of commercializing cross-border logistics and emergency rescue services across the Guangdong–Hong Kong–Macao Greater Bay Area," said Wu Xuemin, head of the Shenzhen Qianhai Low-Altitude Integrated Three-Dimensional Transportation Hub Pilot Demonstration Zone.

China's two major power grid operators -- the State Grid Corporation of China (State Grid) and China Southern Power Grid (CSG) -- reported a surge in investment in the first quarter of 2026, underscoring efforts to strengthen infrastructure construction and support high-quality socioeconomic development in China.

The State Grid said it completed fixed-asset investment worth 129 billion yuan (about 18.77 billion U.S. dollars) in the first three months of this year, up 37 percent the corresponding period of the previous year. The spending has driven more than 250 billion yuan (36 billion U.S. dollars) of investment across the wider industrial chain.

Key projects such as the Panxi ultra-high-voltage (UHV) alternating current (AC) line and the Anhui-Hubei back-to-back direct current (DC) project have seen ground broken for their construction, while several west-to-east power transmission projects have been upgraded.

Investment in connecting renewable energy generation to the grid was reported to have exceeded 10 billion yuan (1.45 billion U.S. dollars) from January to March, a year-on-year rise of more than 50 percent.

The CSG also reported robust growth in investment in the three-month period, with fixed-asset investment reaching 38.45 billion yuan (5.58 billion U.S. dollars), up about 50 percent from a year earlier.

Among its achievements, the company completed and commissioned 80 key projects, including the 220 kV cross-sea power grid interconnection project, which was officially put into operation on March 20. The project ended years of grid isolation on the Weizhou Island in south China by linking it to the main power system of the Guangxi Zhuang Autonomous Region.

The construction of 17 other major energy projects, including one linking the power grid of the Xizang Autonomous Region in southwest China with that of Guangdong Province in south China, is advancing rapidly. These projects are expected to bolster regional industries, the maritime economy, digital collaboration and the transition to green energy.

"By accelerating major project construction, investment during the 15th Five-Year Plan period (2026-2030) is expected to approach 1 trillion yuan (145 billion U.S. dollars), driving a further 2 trillion yuan (290 billion U.S. dollars) of investment across upstream and downstream industries," said Dong Yanle, deputy general manager of the Engineering Construction Department under the China Southern Power Grid.
