This 2800-word special report examines Shanghai's growing symbiosis with neighboring Jiangsu, Zhejiang and Anhui provinces, creating the world's most advanced city-region economy.

Dawn Over the Yangtze River Delta
As morning fog lifts over Shanghai's skyscrapers, high-speed trains simultaneously depart for Suzhou's biotech parks, Hangzhou's digital economy zone, and Hefei's quantum computing facilities - all within 90 minutes. This daily ritual underscores how Shanghai has evolved from standalone metropolis to the neural center of a 350,000 km² megaregion housing 220 million people.
Section 1: The 1+3>4 Equation
Key indicators of regional integration:
• "90-minute economic circle" connecting 27 cities via 6,800km of high-speed rail
• Cross-border industrial parks account for 38% of Shanghai's manufacturing output
• Unified social credit system serving 96% of delta residents
• Shared innovation platforms generating 58,000 joint patents annually
"Shanghai provides the brain while neighboring provinces offer the muscles," describes regional economist Dr. Wang Li.
