Abstract

This study analyzed the efficiency change and the factors affecting productivity change for the six railway operation corporations that are local public enterprises; study was performed with the DEA-CCR Model and Malmquist Productivity Index, using data collected from 2010 to 2014. Since it was not feasible to collect data on the operating expenses and the number of employees of each of the lines, the efficiencies of each operation corporation were analyzed by integrating the operation corporations, and the Malmquist Productivity Index was used to investigate the trend of the periodical productivity change. Average efficiency for urban railway operation corporations was found to be higher in the case of the bigger corporations. In 2014, the Seoul Metro and the Daejeon Metropolitan Express Transit Corporations were analyzed and found to be the most efficient operation corporations. The Malmquist Productivity Index was used to determine the periodical change; the average MPI was 1.06, with a continuous increase of productivity. The analysis showed that changes of technology were generally more obvious than change of technology efficiency for all six operation corporations.

본 연구에서는 지방공기업으로 운영하고 있는 6개의 운영기관의 2010년부터 2014년도의 자료를 가지고 DEA-CCR모형과 Malmquist 생산성 지수를 이용하여 운영기관의 효율성 변화와 생산성 변화요인을 분석하였다. 운영기관을 전체적으로 통합하여 운영기관별 효율성을 분석하였으며, 생산성 변화의 추이를 살펴보고자 Malmquist 생산성 분석을 이용하여 기간별 변화를 살펴보았다. 효율성 분석결과 각 도시철도 운영기관별 평균효율성은 대체로 규모가 큰 기관이 효율성이 높은 것으로 분석되었다. 2014년에는 서울메트로와 대전도시철도공사가 가장 효율적인 운영기관으로 분석되었다. Malmquist 생산성 분석을 이용하여 기간별 변화를 살펴본 결과, MPI는 평균 1.06으로 생산성이 계속해서 증가하는 것으로 분석되었다. 6개 운영기관 모두 기술효율성 변화보다는 기술변화가 대체로 높은 것으로 분석되었다.
