以1 592份长江流域生态环境恢复价值的微观调查数据为例,采用Spike模型估算了南京市居民对流域环境改善的支付意愿及其总补偿价值。结果发现,不考虑＂零响应＂会造成支付意愿的明显高估。南京市居民的支付意愿区间为459-475元/户.年,总补偿价值约为9.43亿元/年;实行差别定价能获取更多的补偿价值,为9.82亿元/年。环境服务为奢侈品,只有收入超过某个最低水平后居民才愿意购买。年龄越高支付意愿越低,以55岁以上老年群体的支付意愿最低。
以1 592份長江流域生態環境恢複價值的微觀調查數據為例,採用Spike模型估算瞭南京市居民對流域環境改善的支付意願及其總補償價值。結果髮現,不攷慮＂零響應＂會造成支付意願的明顯高估。南京市居民的支付意願區間為459-475元/戶.年,總補償價值約為9.43億元/年;實行差彆定價能穫取更多的補償價值,為9.82億元/年。環境服務為奢侈品,隻有收入超過某箇最低水平後居民纔願意購買。年齡越高支付意願越低,以55歲以上老年群體的支付意願最低。

This paper applies Spike model to measuring the willingness to pay（WTP） for Yangtze River basin ecosystem restoring based on 1592 individual questionnaires in Nanjing City.The results demonstrates that no consideration of ＂zero response＂ will lead to the obviously high estimation of WTP.It is also found that the WTP of Nanjing citizens is between 459 and 475 Yuan per year,and the total compensation is 943 million Yuan per year.Environmental services are luxury,and only when people＇s income reaches a certain level will they buy them.The higher the age,the lower the willingness,and people above 55 have the lowest willingness.
