This investigative report examines how Shanghai's expanding influence is transforming surrounding Jiangsu and Zhejiang provinces into an integrated economic megaregion, while analyzing the challenges of balanced development and environmental sustainability.
The Rise of the Shanghai Megacity Cluster
As Shanghai celebrates its 45th year of reform and opening-up, the city's sphere of influence has expanded far beyond its administrative boundaries. The Shanghai Metropolitan Area now encompasses 8 major cities in Jiangsu and Zhejiang provinces, creating what urban planners call "the world's most ambitious regional integration project."
