The development of economic valuation methods based on environmental expenditures for the comprehensive evaluation of ecosystem services

以环境支出为导向的估价方法，例如，相对于重置成本法和陈述偏好法，综合评价的费用规避模型在估价研究领域还没有得到充分的探讨。在这些研究中，日本和中国的饮用水质量，和实际的城市和森林公园使用信息相结合和/或比较的假设场景的选择实验。结果表明，环境支出法和选择实验的相互补充提高了估计结果在边际支付意愿和拟合优度方面的信度和效度。

Environmental expenditure-oriented valuation methods, e.g., averting expenditures model, for comprehensive evaluation have not been fully explored in valuation research fields compared with replacement cost method and stated preference methods. In these studies, drinking water quality in Japan and China, and actual urban and forest park use information were combined and/or compared with choice experiments of hypothetical scenarios. It was demonstrated that reciprocal and complementary use of environmental expenditure method and choice experiments enhance the reliability and validity of estimation results in terms of marginal willingness to pay and the goodness-of-fit.
