Yangtze River Delta Builds Borderless Industrial Zones via Deep Regional Integration

The Yangtze River Delta, China’s most dynamic and innovative economic zone, is advancing deeper regional integration to form borderless industrial clusters. Streamlined cross-regional collaboration has reshaped industrial layout, technological innovation and international trade, delivering prominent scale and synergy effects for high-quality industrial development.

According to Xinhua News Agency, the integrated industrial ecosystem enables full-component sourcing for new energy vehicles within a four-hour transportation radius across the delta. A six-axis industrial robot can be fully assembled on local production lines in merely 12 minutes, reflecting the region’s highly efficient coordinated manufacturing capacity.

Cross-administrative industrial collaboration has broken traditional regional barriers and formed a complete industrial chain covering design, manufacturing and application. Marine engine research and design is conducted in Shanghai, assembly implemented in Jiangsu, and final equipment deployed on Zhejiang transport vessels. Over 70 percent of the engine’s thousands of components are supplied by local Yangtze River Delta manufacturers, achieving same-day delivery and supporting sustained production with orders booked through 2028.

Such integrated industrial layouts have become prevalent across key sectors. Commercial aircraft research, design and final assembly are based in Shanghai, while enterprises in Jiangsu and Zhejiang provide critical supporting components for core civil aviation projects. The biomedical industry also benefits from regional resource allocation, with research achievements developed in Shanghai Zhangjiang rapidly transferred to Wujiang in Jiangsu, shortening commercialisation cycles.

Regional coordination empowers breakthroughs in core technologies. Joint efforts across the delta have broken long-term overseas monopolies in key fields. Advanced carbon-13 isotope industrialisation technologies are developed in Shanghai and mass-produced in Jiangsu and Anhui, with clinical verification completed within the region. AI intelligent sensing devices are iterated through a collaborative model combining Hefei’s technical research, Hangzhou’s product upgrading and delta-wide scenario implementation, enabling domestic substitution of high-end instruments.

Continuous resource mobility fosters emerging future industries. The Yangtze River Delta has formed 36 innovation consortiums in recent years, covering new energy, new materials and nuclear fusion energy. A total of 105 joint research projects focus on integrated circuits, artificial intelligence and biomedicine, with regional output of AI and biomedical industries accounting for one-third of China’s total volume.

Deep integration also bolsters robust foreign trade growth. Data from Shanghai Customs shows the region’s import and export volume reached 6.14 trillion yuan in the first four months of this year, hitting a record high with a 15.9 percent year-on-year increase and accounting for 37.8 percent of China’s total trade value. Local authorities have launched 197 digital application scenarios in shipping, trade and finance, enabling unified inquiry and coordinated processing of cross-border procedures to improve operational efficiency.

The region’s industrial competitiveness gains global recognition. Over half of China’s selected biomedical research projects for the 2026 American Society of Clinical Oncology Annual Meeting originate from the Yangtze River Delta. Optimised industrial ecosystems support local enterprises to participate deeply in global industrial and technological competition.
