Port Authorities from Spain 2014-2022

This dataset contains annual observations on port governance structures, vessel capacity metrics, and market concentration indicators for 20 Spanish port authorities from 2014 to 2022. The data supports the study of how institutional arrangements, market dynamics, and international trade orientation influence port efficiency, particularly in managing vessel capacity. The dataset integrates multiple official sources, including Puertos del Estado’s Statistical Yearbooks and UNCTAD's Maritime Transport Database. It supports econometric modeling using Stochastic Frontier Analysis (SFA) with an inefficiency effects framework.
