Shanghai's Metropolitan Revolution: Building the World's Next Great Megaregion
The lights never dim in Shanghai's Pudong district, where the 688-meter Phoenix Tower stands as a shimmering monument to China's urban ambitions. But in 2025, the real story extends far beyond Shanghai's official boundaries, as the city's gravitational pull reshapes the entire Yangtze River Delta (YRD) into an interconnected economic superorganism.
