地方公共建設與土地稅資本化效果之研究李泳龍, LI, YONG-LONG Unknown Date (has links)
以土地經濟分析之觀點,資本化效果被定義為任何增加或減少房地未來收益屬性的變動,都將增加或減少房地權益價值。就影響因素不同,大致可分為正面及負面資本化效果;而就影響範圍區分,又可分為內部及外部資本化效果。
本研究首先以「淨現值」及「效用最大化」之理念,建立資本化效果之理論模型。接著在實証上,以台北市全區為範圍,擴充過去單年之橫斷面分析,以民國七十五年七月一日至八十年六月三十日之房地移轉個體資料,藉由典型相關分析整合多項地方公共設施之效益權重,排除可能的共線性關係;再透過BOX-COX轉換模式尋求適當函數型態以及二階段最小平方法消除房地價與土地稅間之同步誤差問題。由此分別進行分年橫斷面、時間趨勢面及新舊發展區之資本化效果分析。
結果發現,分年橫斷面之資本化效果呈現不穩定現象,時間趨勢面則呈現出較穩定的資本化效果,而且新舊發展區間之資本化效果有差異現象。此外,以內湖垃圾焚化廠設置為個案研究對象,驗証嫌惡性設施之負面資本化效果。最後將研究結果應用於土地政策上之探討,並提出政策上之建議。

房地價格分離與已開發土地價值分析之研究-以台北市為例 / Analysis of developed land value in Taipei city with housing price decomposition method朱家麒, Jhu, Jia Chi Unknown Date (has links)
近年來,公部門或私部門多有土地價值評估之需要,現今土地交易課稅稅基與私部門投資抵押評估上,多未考量土地與建物個別因素應相互影響價值之因素,導致已開發土地價值評估產生偏誤,故如何合理自房地價格中分離已開發土地價值,是現行土地評價之重要課題。在房地價格分離之相關研究中,如何精準區分土地和建物價值影響因素為其關鍵的基石,而不同房地價格分離方法間差異,亦為本研究探討之議題。
本研究利用特徵價格模型分析方法,以臺北市區分所有建物之住宅交易案例為研究對象,建立複迴歸模型以分離房地價格。實證結果指出臺北市房地價格隨屋齡增加,呈現先遞減後遞增之變化,驗證高屋齡下土地再開發價值之存在,並發現各屋齡分層間土地移轉面積、管理維護對房地價格影響程度不同,藉以有效區分屋齡對土地與建物價值之影響;而現行實務上常見之土地抽取法,在分離房地價格上恐有高估已開發土地價值,以及放大價值漲幅與縮小價值跌幅之問題,顯示其建物成本價值評估過於僵固,將產生偏誤,使建物價值無法有效隨市場景氣變動。此外,透過分量迴歸模型檢驗,其結果顯示已開發土地價值與高屋齡效果間呈現正向關係,亦指價值愈高,其土地再開發價值影響愈顯著。最後,本研究統整相關實證結果,釐清現行房地價格分離上之問題,盼能改善與提升土地價值之評估能力與精準度。 / In recent years, land value assessments have been needed for different purpose. The current assessing of land transaction taxable base and mortgage demands does not consider the individual factors of lands and structures should affect the value of each other, resulting in the developed land value assessment has generated errors. Therefore, how to decompose housing price reasonably and analyze the developed land value is important for land value assessments.
This study establishes multiple regression model by selecting residential condominium sale data in Taipei City as sample, in order to decompose the housing price into developed land and structure value. The empirical results show that the reversion of housing price is due to the redevelopment value, and land area and level of maintenance have impact on housing price in different age variables. Besides, we also find that it has a positive relationship between developed land value and redevelopment value effect on price, and land extraction method probably has some problems in overestimation of developed land value, resulting in miscounting of land price fluctuation. According to the aforementioned, this study concludes with some issues of decomposition housing price for improving and enhancing the accuracy of land value assessments.

都市更新權利變換房地權利價值分離估價之研究黃國義 Unknown Date (has links)
現實生活裡,舉凡土地合建分屋、房地分離課税、徵收補賞、容積移轉、聯合開發、乃至都市更新權利變換等土地價值估價,最終均不免涉及基地因分層使用,而產生的立體地價應如何評估,始符合權益分配公平的問題。
本研究係以成本法計算公式為基本模型,對區分所有建物房地分離估價的拆算方式做一檢視,藉以釐清基地權利價值拆算基礎的爭議,以及立體地價評估模式的應用。
都市更新權利變換前為區分所有建物者,以其房地總價求取區分所有建物之基地權利價值估價,依現行不動產估價技術規則、計有地價分配率、土地開發分析及房地價值構成比率三種分離模式。按理,三種分離模式均為成本法計算公式的應用,在同一估價時點,依相同的估價條件與一致的基礎數據上,三種分離模式之計算公式應可互通使用,拆算結果也應無不同。惟依現行不動產估價技術規則之實際應用上,三種分離模式拆算後之基地權利價值卻有所不同,因此,對區分所有建物之基地權利價值估價,究竟應如何運用三種分離模式的拆算方法,以建立一適當的立體地價評估模式,始不致扭曲其價值之真義,乃為本論文研究之重心。

從房地價格分離探討公告土地現值查估之研究游輝振 Unknown Date (has links)
摘 要
目前我國地價制度是以公告土地現值為核心,但現行公告土地現值嚴重偏離市價,區段內各筆土地相對值極不合理,以此作為課稅稅基及徵收補償的依據,違背賦稅公平原則,為避免稅負漏損,落實漲價歸公,並於土地徵收時作到完全補償,讓公告土地現值趨近於市價,是現階段政府平均地權土地政策「價」的目標。
本研究即以此為論述出發點,從房地總價分離地價的根本查估問題導入,房地分離地價雖是現行公告土地現值查估最重要的價格來源基礎,但因公告土地現值掺雜了素地價和房地分離地價,造成「價」的定位不清、性質不明。經本研究實證結果發現,素地價格區間值相對於房地分離地價是較穩定且乖離率較低,房地分離地價會因建物存在狀態不同而異,且求算過程易受三個貢獻學說爭議的影響,不若素地地價單純,分離地價因含有超額利潤,有重複課稅之嫌,故公告土地現值及基準地價應以定位為「素地價」為宜。
採聯合貢獻所分離出來的地價較採土地貢獻分離地價,更接近素地地價,且與周邊的地價較為均衡,因此房地價格的分離方式應以聯合貢獻說較為合理。現行地價調查估計規則條文過於簡陋,應徹底修訂和不動產估價技術規則接軌,將房地分離方式納入聯合貢獻說的運用,採聯合貢獻分算房地價格時,分算基礎應以含間接成本的建物成本價格為宜,且不動產估價技術規則有關房地分離的相關法規,應予整合統一,房地分離估價方法定義、房地價值比率求算方式,應予明訂。
本研究建議採「價稅分離」,將公告土地現值功能用途單純化,使不同需求之地價回歸其功能目的,讓地政機關查估地價得以切實反應市價。並持續推動基準地地價查估制度,基準地查估不但具有個別宗地估價之精確度,又不失大量估價之方便性,亦能使公告土地現值更趨近於市價,應可改善現行公告土地現值查估制度的諸多缺失。
關鍵字:房地價格分離、公告土地現值、基準地、素地價、區段地價 / Currently, the core of the land value system in Taiwan is based on the Announced Current Land Value(ACLV). However, the ACLV deviates from the market value and the relationship between each parcel of land within the Land Value District is not reasonable. If the ACLV becomes part of the tax base and the foundation for compensation when the land is expropriated, it would be against the fairness and equity principle of taxation. In order to prevent tax loss, put the “Land Increment to the Public” into reality, compensate to the fullest when expropriation, the current goal of the Equalization of Right, the “Land Evaluation” of the land policy by the government is to make the ACLV approximating to the market value.
Based on those issues mentioned above, this research delves into the core issue, the separation of improved property price. Although the land value separated from the improved property price is the most important foundation of the ACLV, the orientation of the value is not certain, and the nature of the value is not clear due to the ACLV is a combination of the land value from the vacant land and improved property. This thesis discovers the vacant land value range is more stable and the possibility of deviation is lower compared to the improved property price. The land value separated from the improved property will differ owing to the difference of the buildings which have already existed, and the controversy resulted from three contribution principles, which makes it more complicated than the vacant land value. If the land value separated from the improved property contains surplus profit, whether the double taxation occurs or not is in doubt. Hence, the orientation of the ACLV and the benchmark land value is better to be identified by the vacant land value.
The separated land value adopting the land-build-united contribution principle approximates the vacant land value more compared to land contribution, and maintain better equilibrium status with surrounding lands. Hence the land-build-united contribution is more reasonable when separated the value from the improved property. Current articles of the “Regulations on the Land Value Investigation and Assessment” are too simplified. It needs to be totally overhauled to be in conformity with the “Regulations on the Real Estate Appraisal.” The land-build-united contribution should be incorporated for the separation of improved property price. The building cost value, which is to be deducted, should consider the indirect cost. Related stipulations of the separation of improved property price should be unified. The definition of the separation approach of improved property price and estimation of the land value ratio and the building value ratio shall be stipulated.
This dissertation suggests the “separation of the evaluation and the taxation” and makes the function and purpose of the ACLV simple. When the land value identified for different function and political purpose is not directly relevant to the ACLV, the ACLV the land administration assess would reflect the market value. The land value benchmark system needs to be implemented continuously. Not only is the precision of the land value benchmark appraisal identical to the individual parcel of land appraisal, but also maintains the efficiency of the mass appraisal as well as making the ACLV closer to the market value, the implementation of the Land Value Benchmark could improve the deficiency of the current Announced Current Land Value system.
Keywords: the separation of improved property price, Announced Current Land Value, Land Value Benchmark, vacant land value, District Land Value.
