Abstract

The purpose of this paper is to provide basic information on how to make better policies that improves efficiencies and to derive policy directions using DEA (data envelopment analysis) model. Through this paper, we can identify whether or not the railroad service has an excellent performance, if there are any structural problems, in which sector it is experiencing a degree of inefficiency, and, therefore, how to set up a realistic target to improve efficiency of railroad transportation. According to the result, we need to introduce a better resource efficient economic strategy to reduce the rail line extension and the number of passenger cars for better efficiency from a public interest perspective, while to widen headways and/or reduce the rail line extension from an economic point of view.

본 논문은 자료포락분석 모형을 이용하여 지역 간 철도의 노선별 효율성을 분석하여, 효율성을 보다 향상시킬 수 있는 정책을 수립하기 위한 기초자료를 제공하고 정책방향을 도출하고자 한다. 본 논문을 통해 철도 운송서비스가 우수한 성과를 지니는지, 구조적인 문제점이 있는지, 어느 부문에서 어느 정도의 비효율이 발생하고 있는지, 운송효율성을 높이기 위해서는 어느 부문에 어느 정도의 목표치를 설정하여야 하는지를 파악할 수 있다. 분석결과를 보면, 철도운송의 공익성을 중시하여 공공성 측면에서 효율성을 개선하기 위해서는 선로연장과 객차수의 절감을 통해, 그리고 수익창출을 중시하여 수익성 측면에서 효율성을 개선하기 위해서는 화차수와 선로연장의 절감을 통해 자원을 보다 효율적으로 사용하는 전략이 필요함을 알 수 있다.
