從 行為學的角度,不動產的估價過程並非絕對的理論,事實上存在有非規 範性的自我主觀,此種特質正是客戶影響可以著力之處。也許因為客戶影響之課 題事涉敏感,相關研究並不多見,僅Levy & Schuck(1999,2005)有較為系統性 的研究,但僅以紐西蘭的估價師為對象,張能政(2004)、汪駿旭(2005)研究及 於影響客戶因素,然不僅國內外文獻,均未同時由委託方與估價方同時進行研 究,因此見解上較難令人信服。此外,Levy & Schuck(1999,2005)指出在較嚴 格的規定下及能較取得較充份且即時的資訊之環境下,較有助於減少客戶影響的 數量和機會。 本研究經問卷調查與訪談結果顯示,客戶影響是一個普遍存在的現象,基 本上在委託前的影響較之委託期間於估價技術或方法的影響更為顯著。至於交易 資訊透明化,對降低客戶壓力的影響,在資訊相當透明的新加坡,卻未必認為資訊透明有助於減少客戶之影響,但資訊透明化確有助於縮小估值調整的幅度。

The subjectivity, discrepancy in the view of the value, creates the opportunities for negotiation to take place between the valuer and client and thus influence the final reported value. However, the topic of client influence has been lightly researched.Levy & Schuck(1999,2005), Chang(2005) and Chen(2006) tried to identify and classify what client pressure can influence valuation. Unfortunately, researchers have focused on the viewpoint of valuer. This study aims to consider the theoretical potential for client influences to bias valuation, and assess the validity of the resulting framework by seeking input from valuers and clients. We conclude clients influence valuation is a common phenomenon and opinion shopping is a most important factor in Taiwan. Moreover, more openness of transaction database more client influence does come into existence in Taiwan and Mainland China, but doesn’t in Singapore. But adjustment range will be smaller in Singapore.
