Efficiency Measurement of Domestic Ports in the Philippines Using Data Envelopment Analysis

抄録

This paper measures the relative efficiencies of select major domestic ports in the Philippines for the year 2018. This study applies the non-parametric model called Data Envelopment Analysis (DEA) to provide the efficiency scores of the eight identified ports. An output-oriented analysis approach was applied for both the DEA constant return to scale model (DEA-CRS) and DEA variable return to scale model (DEA-VRS) to compute for the overall technical efficiency and pure technical efficiency of the ports. Two inputs and three outputs were used in calculating for the relative efficiency scores. Based on the results, the ports of Calapan, Ozamiz, and Panay were proved to be consistently efficient. The ports of Tagbilaran and Batangas were efficient using DEA-VRS but were deemed inefficient in DEA-CRS. On the other hand, the ports of Dumaguete, Puerto Princesa, and Surigao were identified to be relatively inefficient.
