Extending beyond ‘world cities’ in World City Network (WCN) research: Urban positionality and economic linkages through the Australia-based corporate network
本文运用社会网络分析，基于澳大利亚证券交易所上市公司数据，比较四个行业子网络与整体城市网络，发现不同行业有独特的城市间关系配置，为制定全球化城市政策提供参考。
Defining the role of cities within economic networks has been a key theoretical challenge, particularly as nuanced understandings of positionality are increasingly championed over hierarchical notions of influence or power in the World City Network (WCN). This paper applies social network analysis (SNA) to identify the critical role that a wide range of cities plays in the Australian economic system. Drawing upon the set of Australian Securities Exchange (ASX) listed firms, four distinct sub-networks are compared against the overall urban network. Each of the materials, energy, industrials, and financials sector sub-networks are found to have unique configurations of inter-urban relations, which are articulated through institutional and industry-specific factors, grounded in diverse histories and path-dependent trajectories. This analysis applies five different centrality measures to understand how positionality within the overall network and respective sub-networks might better inform policymakers formulating ‘globalizing’ urban policy. This addresses the long-standing theoretical debate regarding territorially articulated hierarchies of urban/corporate power, extricating WCN research from the core-periphery assumptions tied to its world-systems theory lineage. Understanding how, rather than if, cities are global provides contextual knowledge about how cities are situated within broader circuits of production, and the exogenous relations that shape urban economies around the world, providing a framework for research in other global contexts.
