摘　　要：伴随全球城市化发展,超大城市增长迅速。作者分析了1980—2020年35个超大城市的发展趋势,通过对比国家人口和城市人口的增长,揭示超大城市显著的增长速度,并利用首位度、城市集中度、齐普夫指数和熵测度城市体系结构,分析超大城市对城市体系的影响;在此基础上,阐述了超大城市增长的动力机制,分析超大城市对城市发展战略、政策和规划的影响。结果表明:(1)超大城市的增长速度快于国家人口、国家城市人口的增长速度;(2)超大城市的增长使得城市体系结构呈现(至少是局部)发散式的发展;(3)超大城市的增长往往以中小城市的萎缩为代价;(4)超大城市的增长改变了城市发展战略、规划和政策的理念。Megacity grows rapidly along with urbanization in the world. This paper first analyzes megacity growth patterns in 21 countries that have at least one mega city by 2020 with reference to other size cities and their influences on the dynamics of city system in those countries. The paper use four indicators(the primacy, urban concentration, and Zipf’s parameter, and entry) to measure the structural changes of city system and associate them to the emerging megacity. And then the paper examines changes of urbanization strategy in some of countries with megacities and draws policy implications. The paper concludes that 1) the growth rate of megacities could be significant;2) the emerging and development of megacities causes cities diverge at least partially;3) megacity grows sometimes at the expense of the growth of small cities;and 4) the growth of megacities has caused changes in urbanization strategy.
