Conclusion: The Shanghai Model Goes Metropolitan
As Shanghai extends its influence across the Yangtze River Delta, it demonstrates how megacities can drive regional development through economic complementarity rather than competition. The YRD's success lies in its ability to combine Shanghai's global connectivity with specialized competencies of surrounding cities, creating an economic ecosystem that sets new standards for 21st century urban development. This evolving model offers valuable lessons for city-regions worldwide seeking sustainable growth in an era of climate challenges and technological disruption.
