This 2,800-word special report examines how Shanghai and its surrounding cities in Jiangsu and Zhejiang provinces are evolving into an integrated megaregion, analyzing the economic, cultural and infrastructural ties that bind China's most developed area together.
The high-speed rail glides past endless industrial parks and picturesque water towns, connecting Shanghai's glittering skyscrapers with the manufacturing powerhouses of Suzhou, Hangzhou and Nanjing. This is the Yangtze River Delta (YRD) megaregion - an economic powerhouse accounting for nearly 4% of global GDP, where 26 cities across three provinces are increasingly functioning as a single, interconnected urban organism.
Historical Roots of Regional Integration
- Song Dynasty (960-1279): Development of Jiangnan water towns
- Ming-Qing Era: Formation of regional trade networks
- 1980s: Early township enterprises in southern Jiangsu
- 2016: Official YRD city cluster development plan
- 2021: Establishment of YRD Integration Demonstration Zone
"Shanghai has always been both gateway and growth pole for the entire delta region," notes Professor Li Xiang of Fudan University's Urban Research Center.
