Structural Determinism in the Interlocking World City Network

Abstract

Taylor's interlocking specification of the world city network has offered researchers a theoretically informed way to measure the world city network using readily available firm location data. However, the number and size of firms that are viewed as linking cities to one another impose a form of structural determinism on the world city network. Specifically, when a relatively small number of firms is used to define a network among a relatively large set of cities, or when only larger firms are used, this approach is unable to reveal a wide range of structures features that may actually be present in the world city network it is intended to measure. Through a series of examples, I demonstrate how specific features of firm location data predetermine the structure, number and size of cliques, and density of world city networks derived using the interlocking approach. Concluding comments discuss the implications of this structural determinism by focusing on the case of the commonly used Globalization and World Cities data set 11, offer some suggestions concerning how the interlocking approach can be employed while avoiding structural determinism, and identify some alternative approaches to mapping the world city network. © 2012 The Ohio State University.
