Storyline: Smart logistics drives cross-border e-commerce boom in China's Shenzhen [Voice_over] This, this, this — and all of these parcels — collected from across China, are being sent to destinations around the world. It’s happening every second of every day, right here in Shenzhen — China’s No.1 city for cross-border e-commerce. With over 80,000 cross-border e-commerce sellers — nearly half of all those in China — Shenzhen stands at the very heart of the nation’s global online trade. But what’s the real engine of the boom? Innovation. [Stand_up] Bi Ran, Reporter: "This is a smart sorting and inspection system. It can measure a package's weight and dimensions, scan the SKU, and categorize it automatically." [Voice_over] Shenzhen is a launchpad for e-commerce giants and tech firms alike. It’s home to some of the country’s most advanced smart logistics systems — where AI manages supply chains. [Sound_bite] Huang Zhijian, vice general manager, Guangdong Delixun International Logistics Co., Ltd.: "Smart systems have greatly improved our efficiency. Since 2022, we’ve focused on scaling up, with our company growing 60 percent, and top logistics companies in Guangdong up over 50 percent." [Voice_over] Most of Huang's partners and vendors are industry giants like Huolala, Shein, and Shunfeng - major players in transport and retail, many rooted in Shenzhen and key to completing the e-commerce supply chain. Intelligent logistics platforms like Huolala are streamlining the supply chain— with growing R and D investment to keep pace with the industry’s rapid evolution. [Sound_bite] Wang Gong, Director of marketing department, Huolala: "Since 2019, algorithms have been fully integrated into our operations. Built on AI, big data, and advanced mapping technologies, the system uses a self-developed optimization algorithm framework to solve core challenges in resource allocation. So our intelligent platform handles the real-time matching of millions of daily orders with hundreds of thousands of drivers, achieving a vehicle-to-cargo match rate of 92 percent." [Voice_over] Even in global markets, these homegrown smart logistics systems are delivering results. [Sound_bite] Wang Gong, Director of marketing department, Huolala: "The company launched the US last-mile delivery last July. Smart routing cut delivery time to 1.2 days, with a 99 percent delivery success rate." [Voice_over] While freight services form the backbone of Shenzhen’s cross-border e-commerce corridor, drone deliveries are making the network futuristic. [Sound_bite] Heng Shilong, drone captain,Phoenix-Wings: "In Shenzhen, 800 to 1,000 drone flights are made daily to handle over 20,000 package orders. Our fleet currently has 200 drones in operation. " [Voice_over] Unmanned vehicles and drones are now working together in one site, merging ground and low-altitude logistics. The result? A next-gen delivery network — hub, grid, and last mile — built into a very effective system. [Stand_up] Bi Ran, Reporter: "Throughout Shenzhen, this end-to-end drone deliveries can be completed within two hours. For surrounding cities, deliveries can be done by four hours." [Voice_over] Goods can travel from Shenzhen’s Yantian Port to San Francisco on the U.S. West Coast in as little as 11 days through this air-ground-sea network. [Sound_bite] Wu Haifeng, research fellow, Chinese University of Hong Kong Shenzhen campus: "Last year, the cross-border trade from those e-commerce platforms have already exceeded one trillion RMB (about 137 billion U.S. dollars). This one trillion RMB actually will become the economic output in Shenzhen's local economies. So, that is quite important to Shenzhen for further AI or further technological improvement in the future." [Voice_over] From the innovation corridors of Shenzhen to smart warehouses globally, China is upgrading the global e-commerce one smart package at a time. [Restrictions : No access Chinese mainland]
