A port system is a system of two or more ports, located in proximity within a given area. In literature, various geographical and functional scales have been identified ranging from complete coastlines to the notions of a ‘range’ and a ‘multi-port gateway region’. Not only does the spatial scale create confusion on the true functional delineation of port systems, but it also complicates a clear understanding of the relational mechanisms at stake within these port systems.

The latest port study of PortEconomics member César Ducruet and Theo Notteboom revisits existing approaches to and empirical delineations of port systems. Maritime network analysis techniques are deployed to understand hierarchies and interdependencies among nodes of container port systems and sub-systems in North Europe and Northeast Asia. The results provide additional insights on how ports interact from a maritime services’ perspective and demonstrate whether or not ports which are traditionally considered as belonging to the same port system can in reality be considered forming a fully integrated port system.

Cesar’s and Theo’s study has been published in the scientific journal Geojournal. Access journal’s website and download the study for free for 40 days.

Cesar Ducruet

Dr. César Ducruet is geographer and Research Director for the French National Centre for Scientific Research (CNRS) at the research laboratory UMR 7235 EconomiX (Paris-Nanterre University). His research interests include network analysis, urban & regional development, and spatial analysis, through the looking glass of ports and shipping networks, with a special focus on Europe and Asia. After being post-doctoral fellow in South Korea (KRIHS) and The Netherlands (Erasmus University), he joined the CNRS and worked as expert for various organisations (OECD, World Bank, Korea Maritime Institute), and guest lectured regularly abroad. Cesar is a member of the STAR Alliance (HK) and editorial board member of Journal of Transport Geography. After leading the ERC Starting Grant "World Seastems" (2013-2019) he also worked for the World Health Organisation (WHO). He edited two books with Routledge on "Maritime Networks" (2015) and "Advances in Shipping Data Analysis and Modeling" (2017) and co-edited "Global Logistics Network Modelling and Policy" (2021) with Elsevier. He has published more than 50 articles in peer-reviewed journals and 30 book chapters in the last 15 years or so.

About PortEconomics

PortEconomics is a web-based initiative aiming to advance knowledge exchange on seaport studies. Established by maritime economists affiliated to academic institutions in Belgium, Greece and the Netherlands. It provides freely accessible research, education, information, and network-building material on critical issues of port economics, management and policies.
