“Latin American countries, especially those located on the West Coast of South America, have shown significant economic growth in recent years. The objective of this article is to analyze the variables that affect the growth of the Gross Domestic Product (GDP) in Colombia, Ecuador, Peru and Chile, emphasizing variables related to maritime transport, to infer its importance in those countries. The methodology used focuses on a multivariate analysis specifying a panel data model, through which it can be stated that the trend in the four countries regarding the behavior of the variables is common. It is concluded that the maritime transport connectivity index, the volume of containers moved (measured in TEUs), commercial activity and the existence of transregional trade agreements positively affect GDP”.
