我们回顾了关于非市场商品的利益价值估计汇总的文献。通过两个案例研究，我们开发了一种聚合方法，该方法应用地理信息系统的空间分析能力，将地理参考物理，人口普查和调查数据结合起来，以估计空间敏感的估值函数。这些案例研究表明，普遍依赖政治而不是经济管辖权以及在汇总过程中使用样本平均值容易导致结果值出现重大误差。我们还强调了这样一个事实，即对于具有使用价值的资源，我们应该预期总体价值会随着与这些地点的距离增加而减少，但福利措施选择的变化将决定这种“距离衰减”是否会在那些目前非用户所陈述的价值中出现。论文最后提出了对该方法未来改进的建议。(c) 2006 Elsevier B.V.版权所有
We review the literature regarding the aggregation of benefit value estimates for nonmarket goods. Two case studies are presented through which we develop an approach to aggregation which applies the spatial analytic capabilities of a geographical information system to combine geo-referenced physical, census and survey data to estimate a spatially sensitive valuation function. These case studies show that the common reliance upon political rather than economic jurisdictions and the use of sample mean values within the aggregation process are liable to lead to significant errors in resultant values. We also highlight the fact that for resources with use values then we should expect overall values to reduce with increasing distance from such sites, but that changes in the choice of welfare measure will determine whether such 'distance decay' is to be expected within values stated by those who are presently non-users. The paper concludes by providing recommendations for future improvements to the methodology. (c) 2006 Elsevier B.V. All rights reserved.
