摘要
针对收益现值估价法无法合理地估价已探明但未开发或开发时间很短的矿物资源资产这一缺陷。本文综合应用案例决策思想和现代统计理论对矿物资源资产案例估价法进行了研究。首先对属性指标、标的资产、案例资产及案例相似度等关键概念进行了界定,提出了剔除非资源性资产对矿物资源资产价格影响的公式;然后建立了属性强度函数未知情况下案例相似度模型,该模型充分考虑了估价者要加强更相似案例之作用的偏好;最后通过应用实例证明该方法简单易行,只要案例选取得当,估价结果的可信度较高。
Considering that the method of income present value can't appraise mineral resource assets that has been explored but not exploited or exploited for a short time, the paper makes researches on case-based evaluation method for mineral resource assets (for short CEM). Firstly, some key conceptions are defined such as attribute indexes, subject asset, case asset and case similarity, and a formula that can eliminate effects of other assets on the price of mineral resource assets is put forward. Then, a case similarity model under the conditions that attribute intensity function isn't previously acquired is established. The model adequately considers the preference of which valuators emphasize functions of more similar cases.
