摘 要:条件价值(CV)法是评估环境与资源价值的重要手段,后续确定性问题可有效便捷地提高CV结果的有效性。应用10刻度量化表式后续确定性问题对鼓山风景名胜区非使用价值CV评估结果进行校正。问卷采用双边界二分式,面对面调查获得518份有效调查问卷。结果显示:具有正支付意愿的受访者,其付费加入"鼓山保护协会"的确定度呈正态分布,确定度的平均值为6.72;确定度与受访者的收入、受访者对鼓山的熟悉程度呈显著正相关;受访者对起始投标值敏感。当确定度门槛值取7或8时,正支付率从51.5%分别下降至27.8%或23.3%,而平均支付意愿分别从33.24元下降至19.74元或16.36元,采用后续确定性问题校正后CV结果下降了一半左右。Contingent valuation (CV) method is an important method in environment and resource valuation assessment, and follow-up certainty question is just one of the convenient and effective measures to enhance CV validity. We illustrated contingent valuation calibration using fol low-up certainty question with a 10-point Likert quantization table by a case study of Gushan scenic area nonuse value assessment. We employed double boundary dichotomous choice elicitation. The experiment was conducted face to face, and produced a total of 518 valid questionnaire sampies. The action certainty of respondents with positive willingness-to-pay for Gushan Protection Society were normal distribution with mean certainty 6.72. Respondent' s income and his familiarization to Gushan scenic area were significantly positively related to his action certainty, and his action certainty is sensitive to the initial bid. Respondents' positive willingness-to-pay dropped from 51.5% to 27. 8% or 23.3% respectively when certainty threshold value was 7 or 8, and mean willingness-to-pay dropped from 33.24 yuan to 19.74 yuan or 16.36 yuan accordingly. CV result falls by half by followup certainty question calibration.
