| Summary | Recently, considerable attention has been focused on the performance of various ports in terms of efficiency. However, available studies have not provided a satisfactory answer to the problem of few decision-making units (DMU) and a priori specification of input and output weights. Data envelopment analysis (DEA) and assurance region (AR) models were used in this paper to investigate the technical efficiency and pure technical efficiency of the major ports in Taiwan. The DEA technique is useful in resolving the measurement of port efficiency because the calculations are non-parametric, can handle more than one output and do not require an explicit a priori determination of relationships between outputs and inputs, as is required for conventional estimation of efficiency using production functions. The AR approach overcomes the issues caused by free running of input and output weights in basic DEA models. Efficiency measures in this study were based on four inputs and three outputs. The results show the Keelung Port (KLG) is the most inefficient port among the three samples based on constant and variable returns to scale assumptions, mainly due to the enormous slack in their number of labours, total expense, ship berths and tons of tug boats. This study also draws some policy implications for ports and recommends certain areas for future research. |
