Valuation of Use Value on Environmental Goods

환경자원의 이용가치 평가

The contingent valuation method used survey questions to elicit people's preferences for public goods by finding out what they would be willing to pay for specified improvement in them. The method is thus aimed at eliciting their willingness to pay in money amounts. It circumvents the absence of markets for public goods by presenting consumers with hypothetical markets in which they have the opportunities to buy the good in question. The hypothetical markets may be modeled after either a private goods market or a political market. Respondents are presented with material, often in the course of a personal interview conducted face to face. An on-site survey was conducted to 1107 randomly selected P-mountain users using a dichotomous choice questionnaire for the contingent valuation method. Seventeen different bid sets were chosen ranging from the lowest bid of 300won to the highest bid of 2,100won to elicit a reasonable entrance fee in the suggested bid had been determined, and the expected value of willingness to pay was estimated using binary-logit model. The average public value of P-mountain per individual user was estimated to be 1,055.92won∼1,995.61won according to the binary-logit model. The economic value of this P-mountain which includes both use value and existence value can be determined by aggregating the average value giving total willingness to pay for the entire population, in this case 5.491 billion ∼ 10.377 billion.

가상상황 가치평가법은 시장에서 거래되지 않는 비시장재 또는 공공재의 가치를 평가하는데 자주 사용된다. 이 방법은 특정 금액에 대한 응답자의 지불의사를 질문함으로써 특정 공공재에 대한 지불의사확률을 추정하고 이를 binary-logit 분석을 통하여 그 재화의 사용가치를 추정한다. 본 논문에서는 이 방법을 사용하여 P산의 사용가치를 3가지 시나리오를 사용하여 평가하였다. 그 결과 P산에 대한 1회 이용의 지불의사액은 1,055.92월 ~ 1,995.61원이고 매주 10만명의 이용객을 가정할 때 P산의 사용가치는 년 54.91억원 ~ 103.77억원으로 추정되었다.
