Un bel article du New York times (http://www.nytimes.com/2015/07/20/world/asia/in-china-a-supercity-rises-around-beijing.html?_r=1
évoquant la planification des extensions mégapolitaines de Pékin, le retard des services dans les villes nouvelles dortoirs comme Yanjiao, et l'enjeu des transports (train à grande vitesse Pékin Tianjin, en 37 minutes).
Now, high-speed rail is moving toward smaller cities. One line is opening this year between Beijing and Tangshan. Another is linking Beijing with Zhangjiakou, turning the mountain city into a recreational center for the new urban area, as well as a candidate to host the 2022 Winter Olympic Games.
“Speed replaces distance,” Professor Zhang said. “It has radically expanded the scope of what an economic area can be.”
Wang Jun, a historian of Beijing’s development, said creating the new supercity would require a complete overhaul of how governments operated, including instituting property taxes and allowing local governments to keep them. Only then can these towns become more than feeders to the capital.
“This is a huge project and is more complicated than roads and rail,” he said. “But if it can succeed, it will change the face of northern China.”
