For much of the 20th century, the world looked to American cities for a glimpse of the future. Places like New York and Chicago had the tallest skyscrapers, the newest airports, the fastest highways, and the best electricity grids.
But now, just 12 years into the Asian Century, the city of the future has picked up and moved to China. No less than U.S. Vice President Joe Biden recognized this when he said not long ago, "If I blindfolded Americans and took them into some of the airports or ports in China and then took them to one in any one of your cities, in the middle of the night … and then said, 'Which one is an American? Which one is in your city in America? And which one's in China?' most Americans would say, 'Well, that great one is in America.' It's not." The speech raised eyebrows among conservative commentators, but it points out the obvious to anyone who has spent time in Beijing, Hong Kong, or Shanghai (or even lesser-known cities like Shenzhen and Dalian, for that matter).
In these cities, visitors arrive at glittering, architecturally arresting airports before being whisked by electric taxis into city centers populated by modular green skyscrapers. In the not-so-distant future, they'll hop on traffic-straddling buses powered by safe, clean solar panels. With China now spending some $500 billion annually on infrastructure -- 9 percent of its GDP, well above the rates in the United States and Europe -- and with the country's population undergoing the largest rural-to-urban migration in human history, the decisions it makes about its cities will affect the future of urban areas everywhere.
