Resumen
The Spanish port system is subjected to a Data Envelopment Analysis (DEA)-Bootstrapping analysis of its operational and financial efficiency to be compared to two other scenarios. One of these presents a port cluster based on the grouping of ports because of their proximity, and the second scenario proposes a port cluster based on seafronts. The analysis is made up of a DEA-Bootstrapping of two inputs and two outputs for both the operational and financial efficiency analyses. The results of the DEA-Bootstrapping analysis show a series of results that favour these two scenarios against the present situation, as both the operational and financial efficiency are improved in relation to the current scenario or scenario 0.
