Abstract:

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.
