This investigative report examines how Shanghai and its surrounding cities are evolving into an integrated megaregion, creating one of the world's most powerful economic engines while addressing challenges of sustainable development.
The Rise of the Shanghai Megaregion: Blueprint for 21st Century Urban Integration
Introduction
The Shanghai metropolitan area, encompassing 26 cities in Jiangsu, Zhejiang, and Anhui provinces, has quietly become the world's most populous urban cluster, home to over 150 million people. This megaregion now produces nearly 20% of China's GDP while occupying just 2% of its land area - an economic density surpassing both Tokyo Bay and the New York metropolitan area.
