The purpose of this paper is to investigate the effectiveness of FDH( Free Disposal Hull) model for measuring the productive efficiency of world container ports by using the raw data from the previous research by Jun, Il-Soo et al.(1993). The central feature of the FDH model is the lack of convexity for its production possibility set. And the most strong point of FDH model is the ability to classify the dominating and dominated ports with benchmark ports among the container ports. The empirical main results of this paper are as follows: First, inefficient ports are Bremerhaven(0.9883), Antwerp (0.5333), Le Harve(0.95), Kobe(0.9756), Seattle(0.9385), New York(0.6735). The benchmark ports (dominated ports) are the ports of Tokyo(Tokyo), Busan (Busan and Tokyo), Fellixstowe(Fellixstowe), Hongkong(Hongkong), Fellixstowe (Fellixstowe), and L.A (Hongkong and L.A.) each. Second, dominating (dominated) relationships among the ports are as follows. The ports of Fellixstowe(Le Harve, and Seattle), Hongkong(Kobe, and New York), Busan(Antwerp), Tokyo (Bremerhaven, and Antwerp), and L.A.(New York). In order to enhance the productive efficiency for international competition power, the port authorities should recommend benchmarks ports and dominated ports to the inefficient container ports which have shown an efficiency score of below 1.
