於臺灣之都市發展過程中，市場上時可觀察到已開發地區中存在空置或低度利用土地之不連續開發現象（Discontinuous Development），此情形於地狹人稠且土地資源稀少地區將可能產生資源浪費疑慮。何以土地於相同市場環境下呈現不一致之使用決策，其成因值得深入探討，針對此問題，個別土地開發時機決策差異可能為合理解釋之一。有別於以往相關研究由區位及實質選擇權之總體觀點或Evans（2004）所提出之投機及不確定因素等經濟觀點切入分析，本研究乃以個體觀點出發，由土地本身產權條件之非經濟因素為基礎，選定台北市松山二期重劃區商業區土地為研究範圍，觀察於區位、實質選擇權因素對開發之影響力因重劃機制而降低情況下，土地使用決策與土地供給面因素之關係，分別針對土地開發與否及已開發土地開發過程歷時長短、開發前之產權整合情形、未開發土地成因進行探討，進一步建立土地開發與土地產權條件之互動關係，將土地供給面之產權因素帶入土地開發行為分析中。 首先，配合我國之產權條件特徵，本研究以土地面積及所有權權屬狀態作為產權條件指標內容，定義土地面積越大、權屬越單純（所有權人越少、持分狀態越集中）之土地產權複雜度較低，對土地開發具正面效果，反之亦然。立基於以上命題，利用土地登記謄本標示部及所有權部、異動索引及異動清冊資料，整理1984年重劃分回至2013年底研究地區各筆土地之產權條件與歷年產權變動情形。並由敘述性統計、Januszewski Index、Simpson Index、吉尼係數（Gini Coefficient）及賀芬達指數（Herfindahl-Hirschman Index）呈現每筆土地之產權條件特徵。再配合建築執照存根之開發資料，透過Logistic迴歸模型將產權因素與開發行為進行連結。 由迴歸結果可觀察到土地開發與否與面積及權屬因素具顯著相關，當面積越大、權屬條件越單純則土地開發機率將上升，然而，由皮爾森係數計算結果發現土地開發過程歷時長短則似與產權條件無關聯。此外，土地開發前之土地產權整合行為以權屬整合為主，開發者之整合行為具兩階段論，其傾向優先處理權屬分散問題，次考慮最適開發面積之選擇。於未開發土地成因部分，藉由比較已開發土地與未開發土地之產權條件差異，可觀察到大部分未開發土地之面積確實較小、權屬條件較複雜，其土地空置之原因實可以反共有財困境（Anticommons Dilemma）進行解釋，當一資源之所有權分散於多個所有權人手中，則該資源易落入低度使用或空置之情形，產權分散將阻礙資源有效利用。由此觀之，則市場空置土地似可能受制於產權複雜之僵局而無法自主開發利用，於開發行為分析上若忽略此等因素將可能對未來開發趨勢產生過度樂觀之錯誤預期。 / In the process of city growth in Taiwan, discontinuous development can be found in many markets. This condition, especially in the country with limited amount of land, will lead to the dispute over resource. Therefore, what makes development timing of individual land plots different may be the key issue that deserves further examination. Previous studies have found that option value, speculation, uncertainty are possible causes of discontinuous development. In addition to the macro and economic point of view, this study concentrates on land supply as the basis of research. The Songshan 2nd Land Readjustment Project, that is, Xinyi Planning District, where land is equipped with proper infrastructures is selected as the research area. This study takes advantage of this laboratory-like environment to investigate the interaction between land development and land supply. In order to identify land supply, this study uses land ownership information including size, number of owners and respective land share documented in land registration book as the index, and defines land plots with a larger size and fewer owners to be under a simpler ownership. This study proposes that a simpler ownership condition will have positive impact on land development. The empirical study is arranged as follows. First, the descriptive statistics, Januszewski Index, Simpson Index, Gini Coefficient and Herfindahl-Hirschman Index are calculated to show the configuration of land ownership over time. And the development statuses are identified based on the construction permit. Second, the relationship of land development and land supply is constructed by logistic regression analysis. The empirical results imply that the timing of developing land has a strong connection with land supply, and that land plots with a larger size and fewer owners tend to be developed sooner. However, the duration of development progress seems to be independent of these factors. Besides, there are two phases of the land assembly process. Developers tend to deal with fragmented land ownership first, followed by the consideration of development size. Last, the anticommons dilemma serves to be one possible explanation for the vacant or underused plots in the developed area. The anticommons dilemma indicates that if too many owners hold a resource jointly, the resource may tend to stay vacant or underused for the sake of fragmented ownership. The empirical evidence suggests that the vacant or underused plots appear to suffer from the gridlock of property right diffusion. In consequence, the expected development pace may be too optimistic if this gridlock is not taken into consideration.

20世紀初期，以新城建設為特徵的發展形式對大陸地區的農地資源造成極大破壞，在經歷了「空間大躍進」的失敗之後，都市更新成為大陸地區新時期城市建設的的重點方向。台灣地區之都市更新事業早在日治時期就已起步，1998年《都市更新條例》頒布以來已具備完善的制度架構以及豐富的實施經驗。在相似的文化背景之下，作為都市更新的先行者，台灣地區是否能夠給尚處於起步階段的大陸地區提供借鏡意義，大陸地區又能否後來居上為台灣地區的都更困境提供良方？這便是本研究所要探討的課題。 本研究從法令政策及實施效果兩個面向切入，以制度面與執行面對兩岸之都市更新政策與方法進行比較分析。法令政策方面，通過台灣地區都市更新制度以及大陸地區土地產權制度變遷過程之梳理，釐清當前兩岸都市更新的基本流程。本研究認為兩岸都更流程雖然在某些細節存在差別，但總體來說仍十分相似。實施效果方面，本研究選取台北市、上海市以及深圳市三個城市之案例進行分析。在相似的都市更新流程下，兩岸在具體案例的實施過程則表現出政府角色的差異，形成了台灣地區民間主導更新、大陸地區政府主導更新的局面，而這也是兩岸都市更新的主要差異。 本研究認為，土地產權制度的差異是造成兩岸都市更新中政府角色不同的主要原因。換言之，台灣地區土地私有制使得民間成為都市更新的主導者；相對地，大陸地區土地公有制下的土地財政則使得地方政府主導了都市更新。在產權差異的大背景下，兩岸都更在操作方法上並無足夠的相互借鏡意義，因此本研究僅從更新理念上對兩岸之都更事業提出了一定的建議。

過去一般認為，土地供給是固定不變，故價格彈性為零。這樣的思考方式背後隱含需求面才是不動產市場的主導力量，因此土地供給面往往被忽略。不動產僵局的議題近年來不斷出現在世界各國，臺灣社會也不例外。由此觀之，都市住宅供給過程中，似乎不完全由市場需求面主導，尤其都市進入成熟發展階段後，土地供給面的重要程度更應該被突顯。故本研究從供給角度出發，並認為土地面積和產權在都市住宅供給過程中，可能扮演關鍵的角色。透過本研究提出之二維向度分析，也確實發現開發難度和住宅區開發量間存在一定的負向關係，為後續迴歸分析的立論基礎。市場力量或政府力量是否能克服基地面積過小和產權複雜問題，亦是本研究關注之重點。 利用臺北市民國94年到103年的使用執照和拆除執照，以里為分析單元，計算臺北市各里住宅區的樓地板面積淨增加率，並觀察其在空間上之高低分布。影響樓地板面積淨增加率的因素除包含土地面積和產權因素，亦應包括總體因素，區位與政策因素。一般迴歸模型和空間迴歸模型之實證結果顯示：各里中住宅供給多寡主要受到總體因素影響。此外，劃定都市更新地區之政策亦具有吸引建築投資之效果。然而土地面積並非是影響住宅供給之關鍵因素。但本研究進一步發現，在相同條件之下，產權單純對於住宅開發供給多寡的差異，因臺北市區位而有不同，住宅開發供給量由多至少依序為早期發展區、郊區和市中心。且在早期發展地區，產權越複雜的里比起產權較單純的里，住宅供給確實有較少的趨勢，顯示土地產權仍然在臺北市部分地區，造成開發上的問題。 / It is understood that land supply is fixed and the price elasticity is zero, which implies that the side of demand is the dominant force in the real estate market. Because of this the supply side of land is often ignored. The issues of gridlock of real estate development are emerging in recent years worldwide, and Taiwan is no exception. In these instances the market does not seem entirely dominated by demand in the process of housing supply. Especially in cities which have entered a mature stage of development, the importance of land supply should be highlighted. This study is taking the perspective of supply and considering that lot size and land property key roles in the process of housing supply. Throughout this study, we proposed a two-dimensional analysis and indeed found that there was a negative relationship between development difficulty and the amount of residential development, which was the theoretical basis for the subsequent regression analysis. Whether market force or government force can overcome the problems of small lot size and complex land property was also a focus of attention in this study. We used Building Use Permit and Demolition Permit from the year2005 to2014 in Taipei and the analysis units were individual neighborhoods. We calculate net increasing rate of floor area in residential sections of Taipei and observe its distribution in space. Factors affecting net increasing rate of floor area in residential sections include lot size and ownership factors, as well as general factors, region and policy factors. According to ordinary least squares (OLS) and spatial regression, the empirical results show that housing supply in each neighborhood in Taipei is dominated by general factors. In addition, the policy of the delineated renewal areas has the effect of attracting construction investment. However, the lot size was not a key factor in the process of housing supply. Furthermore, the study found that under simple land property conditions, housing supply discrepancies over location in Taipei and supplied quantity in order was the old core, periphery and center. And in the old core, compared to the neighborhoods of simple land property, the housing supply in neighborhoods of complex land property has a decreasing trend which reveals that land property is still causing development problems in parts of Taipei.
