The Dragon's Head: Shanghai as Regional Powerhouse
As China's financial capital and largest city, Shanghai anchors the world's sixth-largest metropolitan economy with a GDP exceeding ¥4.7 trillion in 2024. The city's influence radiates across three provinces (Jiangsu, Zhejiang, Anhui) and one municipality, collectively known as the Yangtze River Delta (YRD) region - home to 16% of China's population generating nearly 25% of national GDP.

- Yangshan Deep-Water Port processes 47 million TEUs annually, serving manufacturers throughout YRD

Shanghai's relationship with its periphery represents a new model of Chinese regional development - not the zero-sum competition seen elsewhere, but a carefully orchestrated ecosystem where each city plays specialized roles while benefiting from collective growth. As the YRD advances toward its goal of becoming a world-class city cluster by 2035, Shanghai's ability to balance its dominance with regional cooperation will determine the megaregion's global competitiveness.
