摘要/Abstract

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。

Abstract: 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 follow-up certainty question with a 10-point Likert quantization table by a case study of Gushan scenic area non-use value assessment. We employed double boundary dichotomous choice elicitation. The experiment was conducted face to face, and produced a total of 518 valid questionnaire samples. 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 follow-up certainty question calibration.

Key words: natural resource and environment economy, value assessment, contingent valuation, validity, follow-up certainty question
