ABSTRACT

We used DEA-SBM(Slack Based Model) to investigate the efficiency of logistics industry in Korea. In order to conduct the study, 11-years samples(2002~2012) of 2,147 Korean logistics companies wereused. We chose fixed asset, liquid asset and labour for input variables and revenue for output variable. We analysed the relative efficiency of the all companies and investigated the trend and features of thelogistics industry. Also by grouping the companies into sub-sectors(marine transport, air transport, landtransport, railway transport, forwarder, parcel service, storage, terminal) and sizes(large, medium, small),we investigated the trend and features of groups. The implication of this study is as follows. First, the efficiency of Korean logistics industry has beenimproved, and it is considered to be the result of Korean government effort to bring logistics industrycompetitive. Second, the efficiency of groups related to global activities such as marine transport, airtransport and forwarder, have been considerably improved and found out to be more competitive and stablecompared to the other groups. Third, air transport and parcel services are growing fast, and the utilizationof their inputs were optimized in an ideal status. Lastly, the efficiency of storage and terminal are measuredto be low because of the oversupply problem in the logistics market.
