Cruise shipping has been extremely popular in recent years, and one of the fastest-growing areas has been the Mediterranean. In the paper, we examine the evaluation of possible competitive–cooperative relationships among Mediterranean cruise ports for the period 2000–2017. To this end, we use three models: the dynamic shift-share model, the Lotka–Volterra model (LVM), and the logistic model (LM). The evaluation of basic market indices is included for completeness. The analysis shows that cruise traffic is in a saturation phase. The shift-share and LVM models reveal that interaction among ports is not significant for the large ports, but could be essential for the small ones.

自2000年以来地中海邮轮港口之间竞争合作关系的发展

近年来，邮轮运输非常受欢迎，而发展最快的地区之一就是地中海。在本文中，我们研究了2000-2017年间地中海邮轮港口之间可能存在的竞争合作关系的评估。为此，我们使用了三个模型：动态转移份额模型，Lotka-Volterra模型（LVM）和逻辑模型（LM）。为了完整起见，还包括对基本市场指数的评估。分析表明，邮轮交通处于饱和阶段。移位共享和LVM模型表明，端口之间的交互对于大型端口而言并不重要，但对于小型端口而言则至关重要。
