Strategic globalizing centers and sub-network geometries: A social network analysis of multi-scalar energy networks

摘要

Over the past three decades, a multitude of studies have examined the relational properties of corporate networks as a proxy for analyzing interurban hierarchies and structures. While this has been important in illuminating the nature of global connectivity, a significant conceptual lacuna exists in understanding how a multi-scalar analysis of interurban networks informs a more complete understanding of the geographies of globalization, and how cities within these networks act as regional globalizing centers. Building upon the theoretical and methodological foundations of 'world city network' (WCN) research, this paper investigates the corporate networks of the energy industry as a historic driver of globalization using social network analysis from an Australia geographical perspective. Globally and nationally scaled energy networks derived from the Platts and Australian Securities Exchange (ASX) corporate lists are used to explore the convergence of nationally and globally articulated networks, and identify cities instrumental in the globalization of the national industry sub-networks. These are strategic 'globalizing centers' which, in contradistinction to 'global cities' or 'world cities' as broad classifications, play nuanced roles in anointing industry-specific circuits of capital and information. The analysis of two complementary yet distinct networks provides theoretical insight into how scale plays an integral role in defining/articulating interurban relations.
