Seasonal Concentration Decomposition of Cruise Tourism Demand in Southern Europe

Abstract

This article analyzes cruise tourism seasonality in Southern Europe, assessing the seasonal concentration levels by means of the Gini index. The additive decomposition of this index is used to evaluate the contribution of each port to the global seasonal concentration in the regions where they are located. It also allows the estimation of marginal relative effects to identify the most propitious ports for reducing seasonality within the Mediterranean regions. The analysis is complemented by estimating the seasonal patterns of each port. Given the significant heterogeneity revealed in the regions analyzed, a bootstrapped bagged clustering is applied to classify the ports into homogeneous groups according to their seasonal patterns. The techniques used form a methodological framework that serves as a control and monitoring tool for measuring seasonal concentration levels in cruise tourism, allowing for policies against seasonality to be tailored for this segment.
