As Professor Li Wei of Tongji University observes: "The Yangtze Delta is writing a new chapter in urban history - not as a single dominant metropolis with satellite cities, but as an organic network where each node strengthens the others while maintaining unique characteristics." With the Delta contributing 24% of China's GDP from just 4% of its land, this experiment in regional integration offers lessons for urban clusters worldwide.
