近年來，社會經濟進步，對「不動產估價」之需求日益殷切，例如投資房地產、利用房地產來進行借貸行為等各項需要，在在皆得依靠不動產估價的技術，因此提升了社會上對不動產估價的重視。而在今日科技如此蓬勃發展的資訊時代，若能將不動產估價的技術與電腦的數位技術相互結合，藉由電腦的強大計算能力與快速的回應能力，相信必能提升不動產估價的技術及準確度。 　所以本研究致力於將不動產估價與電腦科技相結合，期望能提升不動產估價的準確度，除了利用其強大的計算能力之外，本研究更進一步地將不動產估價動作與地理資訊系統ＧＩＳ（Geographic Information System）相結合，利用ＧＩＳ強大的地理資料處理能力，希望能將不動產估價的技術提昇至更高的境界。 　本研究的研究過程為先對不動產估價之理論與方法進行研究，並尋找出不動產估價時的程序及其所需要考量的事項，在整理融會之後，再進一步地結合ＧＩＳ，以建構出一個以ＧＩＳ為基礎的不動產估價系統。且每當一估價個案完成，系統便自動將此筆估價個案之資料與結果回饋（輸入）給系統，成為一筆新增之買賣實例，如此一來，買賣實例資料庫將會愈來愈大，愈來愈完整，也將會使得系統的估價能力愈準確、可信度愈高。 因為在台灣不動產估價已經逐漸受到社會各界，例如銀行、租賃公司和房屋仲介公司等的重視，所以本研究企圖整理出各種常用估價模式及其所需的資料，並結合地理資訊系統（Geographic Information System，GIS）的技術，建構出一個以ＧＩＳ為基礎的泛用型不動產估價資訊系統之原型，期能藉此提高不動產估價行為的效率與精確度，並希望對ＧＩＳ的應用領域提供一個新的窗口，進而擴大ＧＩＳ的長遠發展。 / Recently, the need for appraisal of real estate is more and more important for people. When we invest the money in the real estate or use real estate to borrow money, we must depend on the technique for appraisal of real estate. Now, we are in the information world. If we can take advantage of the ability of the computer to appraise the real estate, it must be able to promote the technique and accuracy of appraisal in real estate. 　So in this thesis, it was applied to combine the appraisal in real estate and the ability of the computer and it hoped that it could increase the accuracy of appraisal. Besides the computing ability, this thesis wanted to combine the technique GIS (Geographic Information System) and the appraisal in the real estate. It wanted to take advantage of the processing ability in geographic data in GIS to higher the technique in appraising real restate. 　In this thesis, we attempt to arrange some general appraisal models and data the models need and to use the technique of GIS to design a prototype appraisal system. We hope that the system will be able to higher the efficiency and accuracy of appraisal in real estate. And we hope we will create a new way to take advantage of the ability of GIS.
