本研究擬以地價人員面對公告土地現值評估時，所形成的心理機制，以計劃行為理論為基礎架構，透過估價相關文獻與社會心理學觀點，尋覓出與本研究相關的外生因素共計6項變數，分別為定錨、從眾、主群體、次群體、自我效能、工作便利性。藉此瞭解影響評估公告土地現值因素，以提供政府機關的參考依據。 經本研究實證結果發現，影響地價人員評估公告土地現值模式內變數，僅有主觀規範未達到統計水準要求，而態度、知覺行為控制皆到達統計水準要求。另外生變數而言定錨、從眾皆會影響地價人員評估公告土地現值的態度。主群體、次群體也會影響地價人員評估公告土地現值的主觀規範。自我效能會影響地價人員評估公告土地現值的知覺行為控制。 / According to mental mechanism that is formed when land-value personnel face the evaluation of announced land current value, the study planned to use the theory of planning behavior as basic frame to find out exogenous factors that are related with the study through documents and social psychology viewpoints related with evaluation.
