摘要: There have been various analyses of the efficiency container port (or terminal) production using Data Envelopment Analysis (DEA) based on cross-sectional data. When time is not considered, results derived this approach can be biased. In order to overcome problem, paper applies DEA windows analysis, utilising panel data, a sample worlds major ports in deduce their relative efficiency. The suggest that estimates fluctuate over time. concludes existing programming methods for estimating are inadequate capturing long-term increased and competitiveness accrue from significant investments.
