摘要: While scholars have studied extensively the individual determinants of willingness to pay (WTP) for improvement in environmental quality, few have delved into the nonparametric nature of such determinants. This study identifies the different major determinants for high and low WTP groups for improvement of water quality in Miyun Reservoir, Beijing. Using QR, interval regression, and Tobit model, this study finds that household income is highly and positively correlated with maximum WTP. In addition, attitude towards the environment, environmental knowledge, demand for improvement in environmental quality, education, and being male are all positively correlated with maximum WTP. In contrast, age is negatively correlated with maximum WTP, consistent with many existing studies. Compared with interval regression and Tobit, QR reveals more interesting results. We find that household income is more significantly correlated with WTP above the median maximum WTP value than below. For the top 1% of maximum WTP group, all nine determinants are highly significant, suggesting that the well-educated ones who command high salaries should be the target group of such policy initiative. By using QR, this paper sheds light on the varying public preferences rooted in income distribution and ability to pay in a fine-grained manner, and thus provides insight into effective policy targeting to implement water policies.
