The Hedonic Travel Cost Method
介绍享乐旅行成本法，通过回归旅行成本与目的地特征来估算用户对户外休闲场所属性的支付意愿，并以华盛顿州溪流中钢头鳟鱼密度为例展示其应用。
The hedonic travel cost method is a technique which reveals how much users are willing to pay for the individual characteristics of outdoor recreation sites. The prices of recreation attributes are estimated by regressing travel costs on the bundles of characteristics associated with each of several potential destination sites. The demand for site characteristics on site quality is then revealed by comparing the site selection of users facing different attribute prices. The technique is applied to value steelhead fish density in Washington State streams.
