摘要:

以流经浙江北部的重要河流东苕溪流域为研究区域,从社会效益的视角,遵循意愿调查评估法的思想和技术,估算东苕溪流域居民对水质改善的支付意愿金额,分析影响支付意愿的主要因素。结果发现:357份有支付意愿,占问卷的65.9%,支付意愿范围为104.01~128.54元,中位数的支付意愿为115.63元/(a·户); 185份零支付愿意,占问卷的34.1%。其中影响流域居民支付意愿度的主要因素为:水质改善应为政府或企业的责任,流域居民不应是水质改善的承担者。同时,家庭人口数、文化程度、是否知道其饮用水源来自东苕溪与支付愿意度成正相关,对自家自来水状况的评价与支付意愿成负相关。基于此,研究提出适当增加水费用于水质改善;建立水环境信息制度,引导广大居民参与决策;严格执行环保标准,减少企业污染物排放等建议。

Abstract:

The East Tiaoxi River(ETR) is one of the dominant branch of Tai Lake Watershed where is one of the most developed area in China. In recent years, water pollution in the ETR has become so serious that the current water quality of some drinking water destrict can’t meet the drinking water district standard grade. This article aims to assess the benefits of water quality improvements in the ETR and adopt the Binary Logistic Model to make empirical researches towards affective factors of the ETR, which is based on contingent valuation method(CVM) questionnaire investigation. Results on a contingent valuation study are shown: 1) 357 of 534 residents have willingness to pay for water quality improvements in the ETR, willingness payment is from 104.01 to 128.54 yuan/(a·home) or 115.63 yuan/(a·home) . 2) 34.1% of the residents have zero willingness to pay for improvement of the water quality in the ETR,the first cause is that they think it is not their duty but government or enterprises’s duty. 3) By using Binary Logistic Model, it shows that resident population, degree of education, knowingness of their drinking water comes from the ETR or not have the positive effects on willingness payment, but satisfaction or not with their own tap-water quality has negative effect. Suggestions are as follows: Increasing water fee to improve the water quality; Founding water environment information system to make residents to know; Executing serious environmental standard to push industries to decrease pollutants.

Key words: willingness to pay, contingent valuation method, water quality improvement, the East Tiaoxi River
