Abstract

The purpose of this study was to examine the efficiency of local waters in Chungnam. The Statistics of Waterworks data released by the Ministry of Environment were analyzed by DEA (Data Envelopment Analysis). DEA is a relatively data oriented approach to evaluate the performance of a set of peer entities called decision making units which convert multiple inputs into multiple outputs. It was possible to obtain significant results on the regional efficiency of local waters in 15 regional, the causes and degree of their inefficiency and what areas one could refer to. It was evaluated that the efficiency of Gun regional was insufficient, and it was found that an improvement policy was needed to improve productivity. This study provided implications for entire local waters operation in Chungnam

본 연구는 DEA를 적용하여 충청남도 기초지자체의 지방상수도 사업에 대한 효율성을 평가하였다. DEA는 여러 종류의 투입 요소를 이용하여 여러 종류의 산출물을 생산하는 유사한 목적을 위하여 결성된 의사결정조직들 간의 상대적 효율성을 평가하기 위해 사용되는 선형계획법의 하나이다. 분석 결과, 충남 15개 시·군 중 CRS 모형에서 7개, VRS 모형에서 8개 지역이 효율적인 지역으로 평가되었다. 반면 절반에 가까운 지역이 효율적이지 못한 것으로 나타났고, 투입과 산출 측면에서 비효율의 원인과 수준을 파악할 수 있었다. 특히 주로 군 지역이 비효율적인 것으로 추정되어 생산성 향상을 위한 개선 정책이 필요가 있음을 알 수 있었다. 본 연구는 충남 지역 지방상수도 운영과 관련된 전반적 의사결정에 시사점을 제공하였다는 점에서 의미가 있다.
