摘要基于中心地理论和新经济地理学关于距离的重要性，本文利用空间数据和最近公布的就业和城市设施普查数据，研究了距离对印度首都地区城市转型的影响。这项研究应用了多环模型，并确定了距离德里特大城市50 公里和100 公里以上的较低层住区的阴影效应。较高级别的居民点对较低级别的居民点产生50 公里宽的阴影，之后后者开始引发增长。人口似乎集中在该地区的特大城市和其他百万以上的城市，以最大限度地利用城市便利设施，这些设施只有在较高级别的中心才能使用。德里附近100多万座城市的发展是一种互补效应。随着离较高等级住区的距离增加，就业机会和城市服务的可获得性减少，从而阻碍等级结构中较低等级住区的增长。文件的结论是，传统的空间分散政策收效甚微，并建议采用以空间为基础的政策，以增加腹地较低级别住区的增长潜力，缩小该区域的空间差距。
ABSTRACT Based on the importance of distance as specified by Central Place Theory and New Economic Geography, this paper investigates the distance effect on urban transformation in the Capital Region of India by using spatial data and recently released census data on employment and urban amenities. This study applies a multiple-ring model and identifies a shadow effect for lower-tier settlements at a distance of 50 km and beyond 100 km from the megacity of Delhi. The higher-tier settlements produce 50 km wide shadow on lower-tier settlements, after which latter starts to trigger growth. The population seems to concentrate in the megacity and other million-plus cities in the region to maximize the utility of urban amenities, which are available only in higher-tier centres. The growth of million-plus cities in close proximity to Delhi state is a complementary effect. As the distance from higher-tier settlements increases, employment opportunities and the availability of urban services decrease, thus hindering the growth of the lower-tier settlements in the hierarchy. The paper concludes that traditional spatial decentralization polices have met with limited success and recommends embracing space-based policies to increase the growth potential of lower-tier settlements in the hinterland and to reduce spatial disparities in the region.
