This paper tries to show the efficiency of water financing between central and local governments. From the year of 2017, the operation and maintenance costs for change water pipes has been provided by central government as block grants system(RDSA: Regional Development Special Account). Even though the water financing is responsible for local government, water drought and high production cost in poor area affects the quality of life nowadays. Then, fiscal transfer through block grant for water financing has been decided to invest regional SOC. The purpose of the paper sheds light on the function of the block grant for public provision by water financing. The firstly tried empirical results are based on the survey from local governments and ministry of environments. The point of the empirical analysis shows that the local governments does not have proper measurement for unexpected water leakage and termination until now. In a policy manner, the paper raises the issues about benefit principle for water users by the increase of tariffs. In order to do so, the paper investigates the relationship between the water provision and fiscal status of each local governments.

본 연구의 목적은 지방자치단체 상수도사업의 효율성을 분석하는 것이다. 먼저, 네트워크분석절차를 사용하여 평가 요소들을 경제적 요인, 환경적 요인, 물공급 요인으로 군집화하고, 군집 내의 각 요소에 대한 가중치를 추정하였다. 그리고 네트워크분석절차에서 추정한 평가 요소별 가중치를 여분 기반 자료포락분석 모형의 가중치로 반영하여 지방자치단체 상수도사업의 효율성을 분석하였다. 이때, 자료포락분석 모형의 투입요소로는 유지관리비, 부채액, 누수량, pH, 탁도, 잔류염소를 사용하였고, 산출요소로는 급수량, 급수인구, 수도요금수입액을 사용하였다. 모형수행 결과, 지방자치단체의 상수도사업에 대한 효율성 순위를 도출하고, 비효율적인 지자체의 벤치마킹 대상을 확인할 수 있었다.
