发展中国家在经济转型期间出现了一些特大城市。对特大城市增长对经济转型的反应进行量化，可以为城市管理者提供重要的影响。本文从城市蔓延类型和土地利用类型两个方面考察了中国最大的特大城市上海的城市蔓延增长，并运用多元回归方法量化了其与经济转型（全球化、分散化和市场化）的关系。利用时间序列航片对1994 - 2006年上海市4种城市用地类型（居住用地、工业用地、交通用地和公共设施用地）的蔓延特征进行了分析。结果表明，城市用地面积呈线性增长，城市蔓延的幅度因城市用地类型和方向而异。城市用地以蛙式和边缘式扩张为主。随着距离城市中心区的增加，城市用地面积呈倒U型变化趋势。城市蔓延与经济转型之间存在正的线性关系。考虑到这三个组成部分的相对重要性，权力下放比市场化和全球化更有影响力。此外，分权化和市场化的综合影响最强。这项研究为特大城市增长问题提供了量化的见解。
A number of megacities have emerged during the economic transition in developing countries. Quantifying the response of megacity growth to economic transition could provide critical implications for urban managers. This paper examined the megacity growth, in terms of urban sprawl, from two aspects (sprawl type and land use type) in Shanghai, the largest megacity in China; and then quantified the relations to economic transition (globalization, decentralization and marketization) using multivariable regression. In particular, the sprawl of four urban land types (residential, industrial, transportation land and public facilities) in Shanghai from 1994 to 2006 was characterized by using time-series aerial photos. Results showed that area of urban land increased linearly and the magnitude of urban sprawl varied with urban land types and directions. Urban land sprawled mainly in the form of leapfrogging and edge. Area of the sprawled urban land exhibited an inverted-U shaped trend with increasing distance from the urban center. A positive linear association was obtained between urban sprawl and economic transition. Considering the relative importance of the three components, decentralization was more influential than marketization and globalization. Besides, the combined influences of decentralization and marketization were the strongest. This study provided quantitative insights into the issue of megacity growth.
