過去文獻對於不動產擔保品估值的研究，通常以銀行最終核定之價格做實證分析，本研究從銀行內部不動產擔保品價格變動情形，來探討影響銀行辦理授信程序時內部各單位決定不動產擔保品價值之因素，就不動產擔保品估值為依變數，實證分析申請人與不動產擔保品各項條件，研究結果顯示分行內部承辦人員估值及總行授審處估值之各項變數中以申請額度、區位、建物面積、屋齡、車位之有無等五項變數對估值具顯著影響。總行鑑價科則在區位、建物面積、屋齡、車位之有無等四項變數呈現顯著，影響總行授審處估值與鑑價科估值差額之因素則以是否為年齡、六個月平均存款餘額及申請額度等變數呈現顯著。分析結果顯示，分行承接業務時，考量擔保品條件與申貸金額。鑑價科則可能因此受到分行內部承辦人員估值的錨點影響，產生干擾效果。而授審處調整擔保品估值金額時，考量還款能力時，可能更重視的是借款戶於本行的往來存款實績。 / Previous studies on the appraised values of real estate collaterals are mostly empirical analyses on the final value approved by the creditor bank. The study, directing its attention to the changes in the appraised value of real estate collateral within a bank, examined the factor affecting the value of real estate collateral appraised by the different units of a bank. With the appraised value set as the dependent variable, the study conducted an empirical analysis on the loan applicants and the various features of the pledged collaterals. According to the study results, loan amount, location of the pledged collateral, floor area, age of the building, and provision of parking space emerged to be variables reaching statistical significance in the appraisal at both a local branch and the head office. Location, floor area, age, and parking space remained the statistically significant variable for the head office. Age of the applicant, average deposit account balance for the past six months, and loan amount appeared to be the statistically significant variable influencing the discrepancy in the values appraised by the local branch and the head office. As indicated by the analysis results, the local branch tended to place greater emphasis on the features of the pledged collateral and the loan amount; the appraisal office at the local branch might therefore be interfered by the value assessed by the responsible appraiser due to the anchoring effect. On the other hand, in adjusting the value appraised by the local branch, the head office would pay considerable attention to the applicant’s overall performance as a bank client in addition to repayment capacity.
