This 2,800-word special report investigates how Shanghai's gravitational pull is transforming neighboring provinces while creating a new model of balanced regional development in post-pandemic China.
The high-speed rail network radiating from Shanghai's Hongqiao hub tells a story of unprecedented regional integration. What economists now call "the Shanghai megaregion" encompasses portions of four provinces, 26 cities, and over 150 million people - all increasingly connected through infrastructure, economy and culture.

Professor Liang Wei of Fudan University observes: "This isn't suburban sprawl - it's the emergence of a polycentric megaregion where each city maintains unique advantages while benefiting from collective infrastructure and talent pools." As this model matures, it offers lessons for urban development worldwide about achieving economic integration without cultural homogenization.
