This 2,800-word special report examines how Shanghai and its surrounding cities in Jiangsu and Zhejiang provinces are evolving into an integrated megaregion that's redefining urban development in China through economic synergy, infrastructure connectivity, and cultural exchange.
The glittering skyline of Shanghai's Pudong district has long dominated international perceptions of eastern China. But look beyond the city limits, and you'll discover an even more remarkable story - the emergence of the Yangtze River Delta as the world's most populous and economically powerful megaregion, with Shanghai at its core.
The Making of a Megaregion
The Yangtze River Delta encompasses:
- 26 cities across Shanghai, Jiangsu, Zhejiang and Anhui
- 225 million residents (larger than most countries)
- $4 trillion economic output (20% of China's GDP)
- 35% of China's total foreign trade
"This isn't just urban expansion - it's the birth of a new economic organism," says regional planner Dr. Zhang Wei.
