本文的目的是估计生态河流修复的非市场效益，并测试其在欧洲第二大河流流域的可转移性。河流恢复减少了洪水风险，改善了水质，其福利影响是衡量在多瑙河流域的三个国家：奥地利，匈牙利和罗马尼亚进行了相同的选择实验。估计的选择模型在偏好和尺度参数方面有所不同。距离衰减的影响被检测到在奥地利和罗马尼亚的水质改善和减少在奥地利的洪水风险。公众对当前水质的看法影响到人们对进一步改善这三个国家水质水平的重视程度。控制这些影响因素，河流恢复政策情景的估计非市场效益似乎可以在匈牙利和罗马尼亚之间转移，但不能在奥地利和匈牙利之间转移。考虑到特定位置因素的作用，如人口密度和城市化程度的差异，使用一个普遍适用的研究设计似乎是必要的，但不充分的先决条件，以减少转移错误时，适用于现有的估计非市场效益的河流恢复从国际文献到新的河流恢复的情况。(C)2015爱思唯尔B.V.保留所有权利。
The objective of this paper is to estimate the non-market benefits of ecological river restoration and test their transferability across the second largest river basin in Europe. River restoration reduces flood risk and improves water quality, the welfare impacts of which are measured in an identical choice experiment conducted in three Danube river basin countries: Austria, Hungary and Romania. The estimated choice models differ in preference and scale parameters. Distance-decay effects are detected for water quality improvements in Austria and Romania and for a reduction in flood risk in Austria. Public perception of current water quality affects the value people attach to further improvements in water quality levels in all three countries. Controlling for these influencing factors, the estimated non-market benefits of river restoration policy scenarios appear to be transferable between Hungary and Romania, but not between Austria and Hungary and Austria and Romania. Given the role of location specific factors such as differences in population density and degree of urbanization, the use of a generally applicable research design seems a necessary, but insufficient precondition to reduce transfer errors when applying existing estimates of the non-market benefits of river restoration from the international literature to new river restoration contexts.
