"Shanghai doesn't just lead - it listens and adapts," observes regional economist Dr. Feng Liwei. "The true breakthrough is in creating a development model where each city's strengths amplify the whole region's competitiveness while maintaining distinctive urban characters."
As the Yangtze River Delta region evolves into what experts call a "mega-city region," its carefully balanced approach to integration offers lessons for urban clusters worldwide - proving that regional success in the 21st century depends as much on collaboration as it does on competition.
