- W2079249915 abstract "기존에는 댐사업의 생활용수 공급편익 산정시 실무적으로 대체댐비용법을 적용하였다. 그러나 해당 댐의 대체시설로서 2순위의 댐을 적용하는 것은 논리적으로 적절하지 않다. 본 연구의 목적은 생활용수 공급사업의 효과에 대한 소비자의 효용을 지불의사액으로 측정하고, 수요함수를 도출하여 편익산정 방법을 제시하는 것이다. 이를 위해 수도권지역에서 1,000가구를 대상으로 생활용수의 사용량 변화에 대한 한계지불의사액을 측정하였다. 그리고 한계지불의사액을을 이용하여 가구별 수요함수를 추정하고, 최종적으로 용수공급 사업의 경제성분석에 적용할 수 있는 월평균 편익산정식을 도출하였다. 제시된 방법론은 적용방법 설명과 토론을 위해 예제로서 송리원댐(현 영주댐)에 적용하였다. 예제 적용 결과, 내용연수인 50년간 총 편익은 약 900억원으로 산정되었다. 본 연구에서 제시된 방법론은 향후 관련 연구 뿐 아니라, 댐 건설사업을 비롯한 생활용수 공급사업에서 경제성분석시 실무적 활용이 가능할 것으로 기대된다. In the past, the domestic water supply benefit of dam has been estimated by replacement dam cost approach. But it is logically inappropriate that we use the second priority dam as a replaced facility. Therefore, this study aims to suggest the estimation method of the domestic water supply benefit by using demand function, which is deduced from Willingness-To-Pay (WTP) of consumers. For this purpose, a survey concerning the marginal WTP is carried out according to the change of water use amount used, targeted 1,000 households in metropolitan area. And by using the marginal WPT, we estimated the demand function of a family. Finally, the monthly benefit equation is derived. The approach is demonstrated and discussed for an example, the Song-Li-Won dam project which is now renamed Young-Ju dam. From the example study, the total benefit for the durable years (50 years), was about 90 billion won. The method proposed herein is expected to be practical and useful in the economic analysis of the domestic water supply project including dam construction, as well as in further studies." @default.
