충주댐 상류지역 하수도시설 확충사업에 관한 주민의 지불의 사액 추정을 위한 CVM의 적용에 관한 연구 = Application of contingent valuation method for estimating willingness-to-pay in planning the intergrated sewerage system in the catchment of Dam Chung-Ju

다국어 초록 (Multilingual Abstract)

The objective of this research was to estimate residents’ willingness-to-pay using contingent
valuation method and to investigate their environmental sensibilities prior to conduct the costbenefit
analysis on the watershed management program of integrated sewerage construction
and operation in the catchment of Dam Chung-Ju. A set of questionnaire was prepared and
asked to 1,200 residents at downstream area as well as upstream area of Dam Chung-Ju. As a
result, environmental sensibility of the residents living in the catchment of upstream of Lake
Chung-Ju seemed very high. However, the substantial practice in their own life for conserving
their environment was inactive, although residents’ efforts trying to collect and dispose
garbages in separate containers and to minimize the waste discharge load were actually made.
The willingness-to-pay on each month for 20 years was estimated as 4,841 wons for the openended
question and 3,411 wons for the close-ended question. Factorial analysis was also
performed to obtain correlation among the questions asked. Seven groups of the correlated
questions were identified and their contribution to the estimated willingness-to-pay was
analyzed.
