This 2,800-word special report examines how Shanghai and its surrounding cities have evolved into an integrated mega-region, creating one of the world's most dynamic economic and cultural ecosystems through coordinated planning and infrastructure development.

[THE MEGA-REGION EMERGES]
From the observation deck of Shanghai Tower, urban geographer Dr. Zhang Wei points northwest toward the shimmering expanse of city lights stretching beyond the horizon. "What was once separate cities are now interconnected nodes in what we call 'Greater Shanghai' - a functional urban region of 38 million people generating $1.3 trillion in economic output," he explains. This is the Yangtze River Delta mega-region in 2025 - a laboratory for regional integration where administrative boundaries blur through high-speed connections and economic interdependence.
[BY THE NUMBERS]
