A Study on the Efficiency Analysis of Certified Integrated-Logistics Company Using DEA Model

Improving the efficiency of logistics companies and logistics industry has become the top priority to all decision-making units for the era of unlimited competition. The purpose of this paper is to analyze the efficiency of 33 certified integrated-logistics Korean companies(CILKC) for 11 years from 2001 to 2011 by using the DEA(Date Envelcpment Analysis) and Malmquist models. The empirical main results are as follows. First, Dongjin, UCTC, Pantos, and KMTC in CCR efficiency and Dongjin, UCTC, Glovis, Pantos, and KMTC in BCC efficiency show the efficient score 1. Dongjin, KMTC, UCTC, Pantos, DTC, KUKBO, CKLlNE, and KCTC whose average values of scale efficiency are 1. This means that those are operated by the economies of scale and effective management, compared to the other CILKC. Second, The Malmquist analysis shows that the average total factor productivity index(0.9994) was decreased by about 6% from 2001 to 2011, because of the backward step of technical change in the logistic industry due the global economic recession. The policy implications are as follows. ① scale expansion by revitalization of 3PL, ② strengthening the custorrer-oriented service, ③ comprehensive plan by govemment for logistics rationalization, ④ tax reduction with consulting support plan for changing cargo companies into 3PL, ⑤ continuous policy for enhancing the efficiency.
