- W2348285718 abstract "The Contingent Valuation Method (CVM) is a direct interview approach that can be used to provide acceptable measures of the economic value of recreation opportunities as well as preservation of natural resources. This latter use is unique to contingent valuation. Contingent valuation methods use simulated (hypothetical) markets to identify values similar to actual markets. The experience gained in US and Europe for about three decades shows that CV is a promising technique which could potentially help public decision-making. Lots of empirical studies conducted in various contexts show that the approach is well-accepted by the general public. The authors take it as an tool to analyze the economic benefits of restoring ecosystem service in an impaired river basin, Heihe river basin, which ranks the second large inland river basin in northwest China. To obtain accurate benefit estimates using CVM technique requires detailed descriptions of the resources being valued. In our survey, a 12-page questionnaire with maps, pictures and figures depicting the reason why the ecosystem of Heihe river basin and Zhangye prefecture has been deteriorating, the measures by which ecosystem services could be restoring from their current level, and the benefits the households in the area could get from restoring ecosystem services. Results from 700 in-person interviews indicate that 96.6% of the households in Heihe river basin would like to pay for restoring the ecosystem services of Zhangye prefecture. Non-parameter analysis of the payment card data shows that the maximum average willingness to pay (WTP) is 45.9～68.3 RMB Yuan per household per year. Parameter analysis of the data indicates that the maximum average WTP is 53.35 RMB Yuan per household per year. The annual aggregate benefits of restoring ecosystem services of Zhangye prefecture is at least 2246.28×104 RMB Yuan, calculated by the number of the households in 1999 in the Heihe river basin. This result is a conservative estimates for the economic value of restoring the ecosystem services of Zhangye prefecture because of the positive externalities of restoring the ecosystem services on the outside of Heihe river basin. This estimated economic value suggests that the general public in Heihe river basin would be willing to pay to restoring the ecosystem services. Thus, the application and development of CVM technique in China should be encouraged because of the necessity of the integrated environmental and economic accounting and the rationally environmental economic decision-making." @default.
