This paper deals with port competition and port selection for cargo to/from Austria. Austria is located centrally in Europe and seaports in at least five countries are used for imports and exports. Changes of market shares over time of different ports serving Austria are analysed. Switching of cargo between ports does take place, but friction prevents instantaneous switching. Consequently, it took a decade for the new potential of inland shipping to Austria, resulting from the opening of the Rhine-Main-Donau canal, was fully realised. A survey was held to analyse port choice decisions of two types of decision makers: shippers and forwarders. These results show shippers and forwarders have similar views on port selection, but shippers have a less price-elastic demand.
