The Shanghai Sprawl: When a Global City Redefines Its Hinterland

The recently completed Shanghai-Nantong Yangtze River Bridge - stretching 11 kilometers across the mighty Yangtze - stands as both physical connector and powerful metaphor for Shanghai's expanding regional influence. As China's financial capital enters its third decade as the "dragon head" of the Yangtze River Delta economic zone, its sphere of influence now extends far beyond municipal boundaries, creating a megalopolis of 110 million people that contributes nearly 20% of China's GDP.

This evolving model may well set the template for urban-regional development across China and beyond.
