| 摘 要： | 本文采用二分式诱导技术，针对广西北部湾四城市当地居民保护滨海生态环境的WTP值进行了测算，并分析了影响其WTP值选择的偏差形成因素。结果显示：①分别应用Logit模型测算得到受访者在未来的5年里，至少愿意支付（204.13~450.17）元人民币（/人·年）来恢复或保护当地滨海区域的良好生态环境；②在测算过程中分别对单边界和双边界模型进行了多重拟合计算，显示单边界的WTP期望值高于双边界的WTP期望值，且两者均高于其简单算术平均值，表明可以减少低估性偏差；③为有效地避免框架锚定效应偏差，在二分式问卷格式基础上，追加了支付卡投标值问项，统计显示选择值大多落在所设定的投标值范围，因而从一侧面验证了本研究不存在明显的框架锚定效应；④对居住环境、环境政策和经济收入满意度高的受访者，其支付意愿明显高于满意度低的受访者，原因在于产生了抗议性偏差。

| Abstract: | Using dichotomous induction technology we estimated the willingness to pay (WTP) for ecological environmental protection or restoration in four coastal cities of the Guangxi Beibu Gulf Economic Zone. The influential factors of deviation in WTP choices were also analyzed. According to a questionnaire survey of 940 people we found that citizens'WTP in the four coastal cities is estimated at 204.13~450.17 CNY per person per year in the next five years to recover or protect the good ecological environment in local coastal areas,and the total economic value is 2.56~5.65×109CNY a year. The expected WTP value in a single boundary is higher than that in the multi-boundary; both are higher than the simple arithmetic mean value. Given that the latter excludes other variables,it is considered that it will reduce underestimate bias to arrive at the WTP expected value in both the single and multi-boundary as the intervals of WTP value. To avoid a framework anchoring effect error,the questionnaire is not designed as a single dichotomous questionnaire,but adds items of payment card bid value. The results show that highest bid value chosen by respondents is within the intervals of the presupposed bid value in dichotomous questions,which indicates that the presupposed value bid is reasonable without obvious framework anchoring effects. The respondents have high satisfaction regarding living conditions, environmental policy and economic income. Their willingness to pay is higher than those who have lower satisfaction and the reason may be because of protest bias. |
