The purpose of this study is to show the measurement way of the efficiency and inefficiency of 32 Korea and China container terminals by using Parallel DEA and CCR(constant returns to scale, input-oriented) models for the period of 2015 with 4 inputs (berth length, terminal yard, number of quay cranes, and number of gantry cranes) and 1 output (container TEU), also especially is to find out the CCR efficient terminals((SGICT, SPICT, SIPGZCT, HPNT, GANGI, GNICT, FICT, DCF)) and Parallel DEA efficient terminals((SGICT, SIPGZCT, DCT) with inefficiency of terminal for the related port. Wilcoxon signed-rank test was used to investigate the ranking changes. The main empirical results of this study are as follows. First, Parallel DEA model is superior to CCR model in terms of efficiency ranking measurement. Terminals of Yidong, YICT, KBCT, CMICT, GOCT, TBCT, Guojigangwu, and PNCT have negative effects to the efficiency of relative ports, because of Parallel low efficiency scores. The efficiency ranking comparisons between the two models of Parallel and CCR using the Wilcoxon signed-rank test were matched with the average level of 89.3 % and 51.6% with or without the statistics of main ports respectively. The policy implication of this study is that Parallel DEA model analysis should be introduced for measuring and increasing the Busan port and terminal efficiency including the clustering with Chinese ports and terminals.
