Competition and complementarity between seaports and hinterlands for locating distribution activities.
Preprint / Working Paper
Monios, J., Notteboom, T., Wilmsmeier, G., & Rodrigue, J.-P. Competition and complementarity between seaports and hinterlands for locating distribution activities

A locational duality in port-related distribution activities is emerging. In some regions, distribution activities have moved from ports to inland locations, driven in part by ‘push factors’ such as port congestion and scarcity of land for container...
