Longitudinal and International Approach to assess 3PL firm's Efficiency using DEA

초록

In this paper, we present the DEA application result, extending the analysis scope to longitudinal andinternational range, to assess 3PL firm’s efficiency. Total twenty-two 3PL firms, located in Korea, Japan, andTaiwan, are chosen for the DEA analysis with following selection criteria such as, considerably large in scale toget listed on the Industry Classification Benchmark (ICB) (2017), and have been listed in the Stock Market andWall Street Journal for more than five years. The data are gathered from the consolidated financial report postedannually on company web sites from 2013 to 2017, which results in total 110 DMUs. The distinguishing featureof this study is that both the individual firm level longitudinal efficiency variations, and aggregated national levelefficiency changes are examined altogether. The DEA computational results offer useful insight for firm levelbenchmarking and national level 3PL policy regulations development. The procedures and computational DEAresults illustrated in this research could be further elaborated in this field.
