【 摘 要 】

Urbanization deserves urgent attentionfrom policy makers, academics, entrepreneurs, and socialreformers of all stripes. Nothing else will create as manyopportunities for social and economic progress. Theurbanization project began roughly 1,000 years after thetransition from the Pleistocene to the milder and morestable Holocene interglacial. In 2010, the urban populationin developing countries stood at 2.5 billion. The developingworld can accommodate the urban population growth anddeclining urban density in many ways. The most importantcitywide projects -- successes like New York and Shenzhen --show even more clearly how influential human intention canbe. The developing world can accommodate the urbanpopulation growth and declining urban density in many ways.One is to have a threefold increase in the averagepopulation of its existing cities and a six fold increase intheir average built-out area. Another, which will leave thebuilt-out area of existing cities unchanged, will be todevelop 625 new cities of 10 million people -- 500 newcities to accommodate the net increase in the urbanpopulation and another 125 to accommodate the 1.25 billionpeople who will have to leave existing cities as averagedensity falls by half.
