우리나라 항만공사의 경영효율성 평가 및 비교

The purpose of this study is to evaluate and compare the managerial efficiency of Port Authority in Korea by using data envelopment analysis(DEA) from 2015 to 2018. The DEA method is a relative evaluation method on the basis of linear programming. The main empirical results of this study are as follows. First, the average technical efficiency of Korea's port authority by year was measured at 0.8419 in 2015, 0.8419 in 2016, 0.8549 in 2017 and 0.8632 in 2018. It indicates that overall efficiency was improving on a yearly basis. However, the total average technical efficiency showed 85.05% which revealed about 14.95% of non-efficiency. Second, DMU1 and DMU3 port authorities show that both pure technology efficiency and scale efficiency are measured at a value of 1, indicating that efficiency is achieved under efficient work and optimum scale. However, it shows that the remaining port authorities are inefficient, and that the reason for inefficiency is due mainly to inefficiency, which is a net technology factor, rather than a scale factor. These port authorities show that they should increase their operating profits and net profits by reducing operating expenses and non-operating expenses rather than adjusting the size of the business with a strategy to improve management efficiency.
