近年來政府將閒置、低度利用的非公用土地以設定地上權之方式釋出,然而,地上權僅為一定期間之土地使用,待存續期限屆滿後,土地權屬則回歸政府,與「有土斯有財」的傳統土地私有觀念相異,因此,非公用土地設定地上權進行活化,對民眾、投資人之接受度是一大考驗。本研究藉由文獻回顧與次級資料之蒐集,了解影響地上權價值之相關理論基礎與現況發展,再與建築開發業者、壽險業者及不動產顧問業進行訪談,了解投資人投標地上權的動機、評估過程中可能面臨的問題、投資地上權案之利弊得失及進行投資時考量之因素,從中建構投標非公用土地設定地上權案之評估架構,可分為不動產市場條件、土地開發條件、地上權招標條件及開發者能力等四個構面;最後運用模糊德爾菲法及分析網路程序法,了解投資人投標非公用土地招標設定地上權案考量之關鍵因素。
In recent years, government liberates the unused and under-utilized national non-public use land by conducting establishment of superficies. Nevertheless, superficies only allows land use for a certain period—after the existence period expires, the land tenure is then returned to the government, dissimilar with the traditional concept of private ownership that says "the wealth comes from land". Thus, activation of establishment of superficies on national non-public use land is extremely hard to be accepted by the public and investors. Through the gathering of literature reviews secondary data, the study aims to understand the related theoretical basis and current development affecting superficies value. Interviews are then conducted with building development industry, life insurance industry and real estate industry consultant; in order to understand the motivation of investors bidding on superficies, evaluate problems that may occur during the process, recognize the pros and cons of investing on superficies, and know the factors to consider when investing. From that, assessment framework of tendering national non-public use land case which conduct establishment of superficies are constructed, dividing into 4 dimensions: real estate market conditions, land development conditions, superficies tender conditions, and developers’ capability. Finally, Fuzzy Delphi Method and Analytic Network Process are applied to understand the key factors considered when investors tender national non-public use land case which conduct establishment of superficies by public bidding.
