港口物流综合效率测度研究

Research on Measurement of Comprehensive Efficiency for Port Logistics

随着世界经济的衰退和我国经济结构的调整,各大港口之间的竞争正从以往的注重外延扩张向内涵式发展转变,从盲目追求吞吐量向提高综合效率转变.目前国内外港口物流的研究中缺乏对综合效率测度的研究,尤其是缺乏X-效率的测算分析.为此,本文在以往研究的基础上,构造了港口物流投入产出的效率测度指标体系,将DEA二次相对评价模型引入到港口物流效率测度中,以生产效率和X-效率测度值为基础,提出了测算综合效率的公式.最后利用此模型对我国13个港口进行了实证模拟,结果表明,该模型适用于港口物流效率的测度研究.

The competition among the ports is changing from focusing on extension to focusing on inner development, and from blindly pursuing throughput to improving overall efficiency, along with the decline of the world economy and the adjustment of China＇ s economic frame. In order to counterbalance the slow development of research on measurement of overall efficiency in port logistics, especially on the measurement analysis of X-efficiency, this paper demonstrates a KPI, which is a measurement of efficiency that deals with the investment and return on investment in port logistics, and introduces DEA quadratic relative evaluation model to measure port logistic efficiency. On the basis of production efficiency and measurement analysis of X-efficiency, this paper put forward a formula to measure the overall efficiency, which supplies a gap in this research. In the end, this paper uses this model to give a demonstration to simulate the relevant operation in 13 ports of China, and the result validates that this model is applicable and appropriate to measure the efficiency of port logistic.
