Integrating world cities into production networks : the case of port cities
Summary (2 min read)
Introduction
- Producer services (APS) to international commodity chains that move through seaports.
- Based upon their empirical findings, the authors conclude that while port-related APS activities predominantly follow the world city hierarchy, a number of port cities stand out because they act as nodes in global commodity flows and as centres of advanced services related to shipping and port activities.
- The focus is on how the dynamics of urban hierarchies is related to the overall restructuring of the world economy (Friedmann 1986).
Integrating World Cities and Global Production Networks
- Rather than providing a complete overview of the conceptual evolution of GCC-GVC-GPN and world city network research, the authors compare them conceptually and methodologically and address how an integrative approach could advance the study of the global economy (for a complete review, see Coe et al.
- Hence, although the concept of network is their core unit of analysis, the respective interests of the WCN school (i.e. international connectedness of cities through corporate networks), and of the GPN-school (i.e. territorial embeddedness of - social - networks involved in global commodities) remain somewhat different in nature and scope.
- The GPN approach takes a more sophisticated and theoretical stand by emphasizing the relational character of networks (Dicken et al. 2001).
- Nevertheless, the authors agree with them that research on GPNs should incorporate more explicitly quantitative data and relevant statistical tools into their analytical apparatus.
- GCC/GVC primarily focuses on the governance of inter-firm relationships, whereas GPN encompasses both intra- and inter-firm relationships and actors such as the state, NGOs, and international regulatory agencies.
Towards an integrated approach
- Recently, the WCN school has started to develop a relational approach.
- More specifically, this contribution recognizes that cities are both embedded within networks (in this case of international operating advanced producer services) and within territorial contexts.
- Thus, despite little evidence about the specific role of APS within commodity chains and global production networks, the aforementioned studies have fostered integration between WCN and GPN frameworks towards a more accurate picture of the „nexus of interconnected functions, operations and transactions through which a specific product or service is produced, distributed and consumed‟ (Coe et al. 2008: 2).
- Such an approach demands that the authors analyse the sector specificity of advanced producer services.
The case of port cities
- Seaports have not received much attention in both bodies of research.
- On the other hand, WCN has largely ignored the significance of commodity flows and the role of APS in relation to these flows.
- Some ports are serviced completely by APS firms located elsewhere, while other port cities will attract more APS firms.
- In port cities and world port cities, urban and port functions coexist in relative harmony and interdependence.
- By combining both data sources, the authors can see how port cities are positioned within the global flow of commodities and within the corporate networks of specialized advanced producer services.
Empirical Results
- The global picture of maritime and port-related APS.
- When the authors look at the global picture of maritime related APS, one of the clearest findings is the dominant position of London.
- In addition, London is set apart in terms of international links, especially with Hong Kong, Singapore, New York and Tokyo.
- The authors data also show the relatively strong position of some cities that do not have a seaport, such as Madrid, Moscow and Paris.
- The position of cities in the graph thus echoes their respective proportion of exclusive linkages with other cities and their relative importance in terms of decision functions.
Relation with Commodity Flows
- Total annual throughput volume per port (in metric tons) is used as measure of port activity.
- There is no straightforward relation between APS establishments and throughput tonnage (the authors do not observe noticeable correlations, cf. Table 3).
- The service centres are port cities that have strong positions within APS networks but not within the physical flows of goods.
- A more detailed picture may be obtained from the comparison of rank in the APS hierarchy and distribution of commodity shares in total port traffic by port city (Table 4).
- Northern range port cities such as Rotterdam, Hamburg, and Antwerp rank high as locations of APS due to the presence of a strong port cluster embedding local and global industries with the port function.
Conclusions
- Based upon their conceptual analysis, the authors developed a topology of locations that are firmly inserted in international physical commodity chains and serve as centres of specialized advanced producer services.
- The concentration of maritime APS firms within non-port cities such as Madrid, Moscow and Paris supports this argument: these specialized APS agglomerate on the basis of something other than commodity flows, like proximity to political-administrative units, APS services in general or proximity to customers (e.g. headquarters of ship owners).
- This inconclusive statement calls for more empirical research in which the following methodological issues should be taken into account.
- Their results indicate that some port cities attract more APS than predicted by their position in the WCN hierarchy.
- Some methodological issues may be addressed, such as an analysis based on morphological and/or functional criteria defining port cities based on port jurisdictions or functional economic areas.

Q2. What future works have the authors mentioned in the paper "Integrating world cities into production networks: the case of port cities" ?
Future research should take into account these points of attention. Further studies that focus on a particular commodity and a specific local context should shed more light on the role of specialized advanced producer services within global production networks. In addition, research may benefit from further application of social network analysis through graph visualization and the use of clustering techniques to highlight the cliquishness of port cities within geographical and/or functional regions of the world. It will also allow us to include specific institutional features into the analysis as well as to assess the role of strategic policy and government agencies in shaping the development paths of port cities in the global economy.
