可比销售法中参照矿业权优选方法优化

Optimizing the Comparable Sales Method by Referring to the Optimization Method of Mining Rights

因为与矿业权市场紧密相关,可比销售法是最容易被交易双方当事人接受的矿业权评估方法。但在应用可比销售法时,需要解决在地质资料数据库中找寻与待评估矿床条件相符的参照矿业权信息费时费力以及如何筛选"近期相似交易环境"的问题。利用模糊决策的方法对地质资料数据库中的参照矿业权信息进行优选,阐述了具体的方法;提出了增加矿产品及矿业权市场条件可比因素的假设。并以24个矿业权案例建立数据库,利用该方法进行优选。研究结果表明O、C、K矿床与待评估矿床的可比因素最为相似,但由于可比因素2物化探异常条件高度不匹配的原因,仍不满足可比销售法的使用条件。为此进行可行性分析,分析结果表明该方法可以对高度相似矿业权信息进行筛选。通过实例分析证明了增加矿产品及矿业权市场条件可比因素的合理性。

Comparable sales method is closely related to mining rights market,so it is the most acceptable mining right evaluation method for both parties involved in the transaction.However,when applying the comparable sales method,it is necessary to solve the problems of time-consuming and laborious searching for the reference mining right information in the geological data database which is consistent with the conditions of the deposit to be evaluated and how to screen"recent similar trading environment".Therefore the fuzzy decision method was used to optimize the reference mining right information in the geological data database.The hypothesis of increasing comparable factors of mineral products and mining right market conditions was put forward.And then,a database of 24 mining rights cases was established and optimized by this method.The results of the study showed that the O,C,and K deposits were most similar to the comparable factors of the deposits to be evaluated.However,they were still not met the conditions of the comparable sales method as the high mismatching of the comparable factor 2.The feasibility analysis showed that this method could screen highly similar mining right information.The feasibility analysis showed that this method could screen highly similar mining rights information.And then,the rationality of increasing the comparable factors of mineral products and mining right market conditions was demonstrated with the example analysis.
