Abstract

There is imminent need to find a way to measure the recreational benefits of water so that appropriate actions can be taken to make a multi-purpose reservoir. Therefore, this study attempts to apply a choice experiment to quantifying the recreational benefits of a multi-purpose reservoir, using a specific case study of Sangkwan multi-purpose reservoir. We consider the trade-offs between price and attributes of recreational attributes for selecting a preferred alternative and derive the marginal willingness to pay (MWTP) estimate for each attribute. The results show that the MWTP for providing additional 10,000 ton of water is estimated to be 3 won per household per year. The MWTP for improving 1 level of water quality is computed to be 645.5 won per household per year. Moreover, the MWTP for providing recreation facilities is calculated to be 1,518.6 won per household per year. This study allows us to provide policy-makers with useful quantitative information that can reduce uncertainty in the decision-making process related to a multi-purpose reservoir construction projects.

물에 대한 기능 중 레크리에이션 기능은 빼놓을 수 없는 중요한 기능중의 하나이다. 그러나 레크리에이션 편익에 대한 정량적 연구는 매우 미흡한 실정이다. 이에 본 연구는 실험선택법을 적용하여 레크리에이션 편익을 추정하고자 한다. 레크리에이션과 관련된 몇 개의 속성과 가격속성으로 이루어진 여러 개의 대안 중에서 선호하는 한 가지를 응답자로 하여금 선택하게 함으로서 개별 속성에 대한 한계지불의사액(MWTP) 정보를 도출한다. 분석결과 레크리에이션 용수 10,000톤의 추가적인 확보에 대해 각 가구는 연간 3원의 MWTP를 갖는 것으로 추정되었다. 또한 레크리에이션 용수의 수질을 1등급 개선시게 되면 각 가구는 연간 645.5원의 MWTP를 갖는 것으로 분석되었다. 아울러 레크리에이션 시설의 추가적인확보에 대해 각 가구는 연간 1,518.6원의 MWTP를 가졌다. 이와 같은 정량적 정보는 다기능 저류지 조성 여부와 관련된 의사결정에서 유용한 정보로 활용될 수 있을 것이다.
