Port development is challenged not only by growing trade flows, but by institutional conditions that are more contextual, exhibiting aspects of both path dependence and contingency. This paper analyses the intersection of two clear trends in the evolution of port systems, decentralisation of port governance and deconcentration of port traffic. The goal is to identify how the institutional setting governing the spatial diversification of container port activity has changed as a result of this intersection and whether it is suitable to deal with new challenges as they arise. An additional question is whether the new institutional settings created by port reform in developing countries are suitable to support the successful application of port devolution policies imported from developed countries with different political and institutional histories.
