【摘要】：选择实验法是当前国内外用于分析资源环境价值的前沿方法,可以用来估算居民心中公共物品的经济价值。目前我国少有学者将该方法应用于湖泊水资源价值评估。论文尝试将选择实验法引入湖泊水资源非市场价值评估中,以安徽巢湖为例展开实证研究,建立多项对数模型(Multinomial Logit)和混合对数模型(Mixed Logit)对巢湖水资源非市场价值进行测算。主要研究结果表明:1城镇居民的支付意愿普遍高于农村居民;2三个属性中,城乡居民对湖泊自然景观的关注度最高,其次是长江水引入量,最后是水体富营养化;3基于多项对数模型估测未来10年巢湖水资源非市场价值约为60.74亿元/年,其中城镇居民年均支付意愿为160.8元/户,农村居民年均支付意愿为9.9元/户;而基于混合对数模型估测未来10年巢湖水资源非市场价值约为44.66亿元/年,城镇居民年均支付意愿为111.75元/户,农村居民年均支付意愿为21.77元/户。
[Abstract]:The selective experiment method is the frontier method used to analyze the value of resources and environment at home and abroad. It can be used to estimate the economic value of public goods in residents' hearts. At present, few scholars in China have applied this method to the evaluation of lake water resources value. This paper attempts to introduce the selective experimental method into the non-market value assessment of lake water resources. Taking Chaohu Lake, Anhui Province as an example, an empirical study was carried out. The multivariate logarithmic model and mixed logarithmic model were established to measure the non-market value of water resources in Chaohu Lake. Urban and rural residents pay the most attention to the natural landscape of the lake, followed by the amount of water introduced into the Yangtze River. Finally, the eutrophication of water body is estimated to be about 6.074 billion yuan per year in the next 10 years based on multiple logarithmic models. The average annual willingness of urban residents to pay is 160.8 yuan per household, and that of rural residents is 9.9 yuan per household, while the non-market value of Chaohu water resources in the next 10 years is estimated to be about 4.466 billion yuan per year based on the mixed logarithmic model. The average annual willingness of urban residents to pay is 111.75 yuan per household, while that of rural residents is 21.77 yuan per household.
