This in-depth report examines how Shanghai serves as the core of an increasingly interconnected Yangtze River Delta region, driving economic growth and cultural exchange across eastern China.

The skyline of Shanghai's Pudong district gleams like a jewel in China's eastern coast, but its true significance extends far beyond the city limits. As the anchor of the Yangtze River Delta region—China's most economically developed urban cluster—Shanghai's influence radiates across three provinces (Jiangsu, Zhejiang, and Anhui) and 26 cities within a 100-mile radius.
Regional integration has accelerated dramatically since the 2019 Yangtze River Delta Regional Integration Development Plan. Key statistics reveal the scale:
- The delta contributes nearly 25% of China's GDP with just 4% of its land area
- High-speed rail connections now link all major delta cities within 90 minutes of Shanghai
- Cross-border commuters have increased 300% since 2020, with over 850,000 daily intercity travelers
Transportation innovation drives connectivity. The newly expanded Hongqiao Transportation Hub serves as the region's beating heart, handling:
1. High-speed rail connections to Nanjing (60 minutes), Hangzhou (45 minutes), and Hefei (90 minutes)

- Develops joint flood control systems for the low-lying region
As Shanghai prepares to host the 2025 World Expo, the entire delta region stands ready to showcase China's urban future—not as isolated cities, but as an interconnected megaregion setting global standards for coordinated development.
