基于极效率DEA模型的港口绩效评价

对集装箱港口的绩效进行评价一直是港口当局关心的问题，现有文献尚未提出比较有效的方法，尝试利用极效率(super-efficiency)DEA模型对集装箱港口的绩效进行评价。极效率DEA模型能够有效地区别出有效(绩效值1)决策单元之间的绩效差异，可以对所评价的决策单元进行有效的排序。此方法已在城市和企业的评价中得到了应用，但尚未在港口得到应用。在案例中，汉堡港最有效率，新加坡港次之，然后是香港港、泽布勒赫港和基隆港，香港港由于船舶的无效逗留时间长、新加坡港集卡数配置不合理，导致两者的绩效低于吞吐量远小于它们的港口。

Efficiency Measurement of Ports Based on Super-efficiency DEA Model

Available studies have not provided a satisfactory answer to the problem of measuring the ports efficiency. DEA has been applied to a wide number of different situations where efficiency comparisons are required. The DEA technique is useful in resolving the measurement of port efficiency because the calculations are non-parametric, can handle multiple (output) and input. In this paper, the super-efficiency data envelopment analysis(DEA) was used to provide an efficiency measurement for selected ports and rank the selected ports. Some factors affecting ports efficiency were also been discussed in detail.
