Analysis on Efficiency of Hub Ports in Northeastern Asia Based on DEA Model

Twenty-two hub ports in Northeast Asia were analyzed in an empirical way based on the Technology Efficiency Model, Pure Technology Efficiency Model and Scale Efficiency Model in Data Envelopment Analysis (DEA). Five input indicators and 1 output indicator were selected in this study and the average value in 4 years in the CCR model was 0.55, 0.65 the in BCC model, and 0.84 in the SE model. Analysis data revealed that irrespective of the strategic differences of each port, the scale efficiency of each port is reasonable on the whole, though non-efficient application in terms of technology still exists. Therefore, efficient ports and non-efficient ports were compared in the analysis and indicators of non-efficient ports needing improving and corresponding improvement were put forward.
