摘要

房地產估價事關重大公共利益，但其官方理論——以過去與當前條件下的市場價值意見為核心——與估價產品在當代金融流程中的實際用途之間的張力正日益加劇。本文分五個階段建構這一論證，每個階段均配有明確、可查詢的 Prolog 知識庫：前兩個階段確立估價所承擔的社會與經濟功能；第三個階段指出其主要最終產品——市場價值意見；第四個階段考察估價相對於量化預測與金融預測的時間取向和方法論取向，以及將兩者分隔開來的監管邊界。這些內容匯聚為第五個階段的核心主張：在抵押貸款中，按貸款價值比折算的市場價值實際上充當著未來法拍價值的隱性替代指標——這是一種面向未來的用途，而現值理論並不予以承認。許多估價師並未意識到這一擔保品估值角色，因而未能以應有的審慎態度對待市場價值的未來走勢——本文旨在揭示這一問題，並歡迎後續研究。
