World City Network Analysis
Research Guide
What is World City Network Analysis?
World City Network Analysis applies network theory to quantify inter-city connectivities based on flows of advanced producer services, capital, and information across global urban hierarchies.
Researchers use data from firm office networks to construct interlocking network models measuring city centrality and connectivity changes over time. Key methods derive from the Globalization and World Cities (GaWC) research group, analyzing 315+ cities via service firm presence. Over 10 papers from Taylor, Derudder et al. (2002-2017) provide foundational datasets and metrics, with Taylor & Derudder (2003) cited 1209 times.
Why It Matters
World City Network Analysis reveals hierarchical shifts in global urban systems, informing policy on economic inequalities and infrastructure investments. Taylor et al. (2002) enable measurement of intercity relations for 391 citations' worth of studies on globalization impacts. Derudder et al. (2010) track connectivity changes from 2000-2008, applied in urban planning for emerging markets like China (225 citations). Bassens et al. (2009) map Islamic financial services networks, guiding fintech strategies in 115-cited analyses.
Key Research Challenges
Data Construction Variability
Interlocking network models rely on firm office data, but firm selection and size thresholds vary across studies. Taylor et al. (2002) specify criteria for measuring intercity relations, yet replication faces inconsistencies in service sector coverage. Derudder & Taylor (2017) highlight comparability issues in central flow theory (127 citations).
Capturing Dynamic Changes
Quantifying temporal shifts in connectivities requires repeated data collection over decades. Derudder et al. (2010) analyze 2000-2008 pathways, but short intervals miss long-term trends. Taylor & Aranya (2008) detect 2000-2004 'roller coaster' effects, complicating causal inference (117 citations).
Beyond Producer Services Bias
Focus on advanced producer services overlooks air travel, migration, or digital flows. Bassens et al. (2009) extend to Islamic finance but note gaps in non-Western data. Van Meeteren et al. (2016) disentangle agglomeration from network effects, urging multi-flow integration (113 citations).
