e overall petitiveness of national economies. Cullinane and Song (2021) point out that ports constitute a critical link in the supply chain and that their level of efficiency and performance influences, to a large extent, a country’s petitiveness. Similarly, Sanchez et al. (2021) in the context of a number of Latin American countries, showed that port efficiency is a relevant determinant of a country’s petitiveness and interestingly they add that, unlike most other relevant variables, port efficiency can be influenced by public policies. Bryan et al. (2021) provide a prehensive review of the literature generally on ports and regional economic development and, taking the case of ABP’s port activities in SouthWales, they quantify the economic significance of that set of ports activities on the issues then have generated the drive today to improve port efficiency, lower cargo handling costs and integrate port services with other ponents of the global distribution work. 4 4. Conclusion and remendations for further research Ports have evolved from being simple transhipment points and can provide a range of services and activities to support the wider supply can be of benefit to supply chains by making them both more efficient and effective, while allowing ports to bee more profitable. The important, sometimes even critical, role which ports play in supply chains should not be underestimated. The emerging area of portcentric logistics, as outlined in this paper, is an area of potential revenue generation for ports. This is especially relevant given the changing nature of the ports sector which is characterised by inter alia increased petition between ports, changing port ownership structures, and more powerful shipping lines. Where ports traditionally may have had some “captive” traffic, this can no longer necessarily be taken for granted. Notwithstanding all of these challenges (which in any event should not be seen as obstacles by good researchers!) the unearthing and analysis of accurate data could, we believe, be of major benefit to the ports and logistics sector, and to those of us who research in these sectors, and particularly so if it can lead to greater insights into the emerging area of portcentric logistics. Ports need to move from taking a passive role in the supply chain to a more active r
