In this paper, we analyze the determinants of maritime and road transport costs for Spanish exports to Poland and Turkey and investigate the different effects of these costs on international trade. First, we investigate the extent to which maritime and road transport costs depend on different factors such as unit values, distances, transport conditions, service structures, and service quality. Second, we analyze the relative importance of road and maritime transport costs as determinants of trade flows. The data on transport costs are drawn from a new database compiled from primary data sources. The main results of this investigation identify the central variables influencing road and maritime transportation costs: for both modes, transport conditions are strong determinants, whereas efficiency and service quality are more important for maritime transport costs, and geographical distance is more important for road transport. Road and maritime transport costs are important explanatory factors of exports and they seem to deter trade to a greater extent than road or maritime transit time when considered endogenously determined.
