초록

본 연구는 우리나라 도시철도들의 수송효율성을 분석하여, 수익성 측면에 있어서의 효율성을 향상시키기 위한 정책방향을 제공하고자 수행되었다. 본 연구를 통해 우리나라 도시철도들의 상대적 효율성을 측정하고, 효율성이 부족한 도시철도 노선에 대해 구조적인 문제가 존재하는지를 분석하였다. 분석대상은 전국 공공기관이 운영하는 17개 도시철도 노선이며, 자료포락분석기법(DEA)으로 노선별 효율성을 분석하였다. 분석된 결과로부터 규모의 경제성을 도출하고, 외부요인으로서 무임 손실비용과 운임제도에 따른 운수수입에의 영향정도를 파악하였다. 이 때 분석을 위한 변수로는 다중회귀분석을 통해 도출된 차량수, 운행횟수 두 생산요소를 투입하여 운수수익을 산출하는 형태로 상정하였다. 마지막으로 자료포락분석기법으로 도출된 효율성값을 다차원척도법(MDS)에 적용하여 전국 도시철도에 대한 수익성 측면의 효율성 향상방안을 제시하였다.

The purpose of this study is to analyze transport efficiency of each of the 17 urban railway lines being operated by national public agencies using Data Envelopment Analysis (DEA) and to seek strategies for improving efficiency of the urban railway system. The study identified the economies of scale derived from these values of efficiency and examined the effects on cost for free ride loss and profit of transport by the fare system as the external factor. At the time, Transport profits are estimated by two production factors such as the number of vehicles and service frequency derived from multiple regression. Finally, the measures to improve the efficiency were presented in terms of profitability in the national urban railway line by applying the values of efficiency derived from DEA to multidimensional scaling (MDS).
