Prime Locations
摘要
We develop a method for delineating prime locations—ultra-dense clusters of economic activity—within cities and apply it to comprehensive establishment data covering all US metropolitan areas. We further use big data to extend the analysis to a global context where administrative data are sparse. Many cities in the US and around the world are dominated by a small number of prime locations that can concentrate up to one-half of tradable services jobs on tiny shares of land and are dominant centers of economic gravity. In cities with fewer prime locations, a larger tradable services share concentrates in them.
中文摘要
我们提出了一种在城市内部划定核心区位（即经济活动超密集集群）的方法，并将其应用于覆盖美国全部大都市区的综合性企业数据。进一步利用大数据将分析扩展至行政数据稀缺的全球范围。美国及全球众多城市的核心区位数量有限，这些区域能以极小比例的土地集中高达一半的可贸易服务业岗位，并成为主导性的经济引力中心。在核心区位较少的城市中，可贸易服务业岗位的集中度更高。
