Abstract

This study analyzes the relative efficiences through satisfaction on taxi services of thirty-one cities and counties in Gyeonggi Province. The DEA (Data Envelopment Analysis) is used to measure efficiencies on the privately owned taxies and the corporate taxies respectively. Efficiency in the DEA is measured relative to the highest observed performance rather than against some average. Pyeongtaek, Pocheon, Osan, Yangpyeong, and Gapyeong have the highest efficiency in the private owned taxies. And Pyeongtaek, Pocheon, Osan, and Gapyeong have the highest one in the corporate taxies. These cities and counties have the ability to use less resources for equal efficiency relative to others. Rank-sum test proves that there is no statistical difference in efficiency between the privately owned taxies and the corporation owned taxies.

본 연구는 경기도내 31개 시군에서 운행되고 있는 택시의 서비스에 대한 만족도를 기초로 지역별 택시의 효율성을 평가하였다. 효율성 평가는 개인택시와 법인택시로 구분하여 분석하였다. 시 군별 효율성 평가는 DEA(Data Envelopment Analysis) 모형을 이용하였다. 본 연구에서 사용한 자료는 경기도 31개 시 군의 개인 및 법인택시를 대상으로 조사한 자료이다. 31개 지자체의 효율성 평가 결과를 살펴보면, 개인택시의 경우 효율적인 지자체는 평택시, 포천시, 오산시, 양평군, 가평군 등 5개 지자체로 나타났다. 법인택시는 평택시, 포천시, 오산시, 가평군 등 4개 지자체이다. 이들 지자체들은 일정한 수준의 만족도를 생산함에 있어서 다른 지자체보다 적은 양의 서비스를 사용하는 능력을 확보하고 있음을 의미한다. 개인택시와 법인택시간 DMU들의 통계적 차이가 있는지를 검증하기 위하여 순위합검증(Rank-sum Test)을 시행한 결과 두 집단 간에 서비스제공에 따른 만족도 차이는 없는 것으로 분석되었다.
