A City-Networks Perspective on the Global Economy  


A popular approach to conceptualising the global economy has been through the lens of network science, in which cities act as economic ‘hubs’, and the connections between them as ‘spokes’. Such connections refer to various types of flows, including information, resources, and capital. This presentation provides an overview of how the ‘global network of cities’ can be conceptualised from the perspective of global corporate networks, in this case using data on connectivity between firms and their subsidiary locations. Drawing upon data from 1.1 million corporate records, it reports on the findings of a multi-year ARC project focussing on firm networks. The presentation will provide a broad overview of network science and its applications in economic geography, followed by a more detailed set of findings relating to how and why network connectivity occurs, and what this means for contemporary cities and their global economic dimensions.
