Headquarters,office employment,and the wave of urbanization in the New York City region

Hierarchical theory suggests that high-density office activity, such as corporate headquarters, epitomizes the concept of agglomeration. This research tests whether office employment in a metropolitan area agglomerates around suburban nodes of specialized office and corporate headquarter activity or if office employment change shifts in response to the wave of urbanization. The location of the Fortune 500 manufacturing and service headquarters and the ratio profiles of office employment within each county are used in the test. We conclude that headquarters are not located in specialized office employment nodes. Rather, the office employment becomes specialized as the county becomes more urbanized.
