This investigative report explores how Shanghai's $420 billion regional integration strategy is creating the world's most sophisticated city cluster, connecting 27 municipalities across three provinces into a unified economic powerhouse.
The shimmering skyline of Lujiazui no longer represents Shanghai's boundaries - it now serves as the command center of an interconnected metropolitan network producing 24% of China's GDP. This unprecedented urban experiment combines Shanghai's financial muscle with Jiangsu's manufacturing prowess and Zhejiang's tech innovation in what planners call "the world's most ambitious regional development initiative."
