現今由政府所主導土地開發，常因開發方式的僵固化而造成公平與效率的爭議，本研究的目的即在於尋找另一種新的土地開發方式──浮動開發，希望能有效地解決爭議而達成開發目標，並以南二高交流道特定區開發為例，模擬浮動開發之運作模式，使其能落實應用。

　　本研究首先探討現行國內土地開發方式的優缺點及比較國外彈性土地開發方式之功能目的，期望能從中找適合國內的開發模式。結果本研究採用浮動分區(Floating Zone)為主要依據，配合現實環境，研擬出二階段浮動開發模式及運作流程，並以理性預期理論及獨占理論來說明浮動開發的立論依據，進而探討其特性及限制面，同時與現行土地開發方式作一比較。

　　另外，浮動開發的基礎在於協商的運作，因此本研究從協商的基本意義及目的作探討，並針對土地開發協商，尋找國內外範例來分析其優缺點及運作情形，進而建立二階段二部分之浮動開發的協商模式。

　　在模擬應用浮動開發於交流道特定區時，首先進行交流道特定區的特性分析，並以中山高交流道特定區的開發情形作檢討，而認為其開發成果並不理想，實因受限於土地開發的不合理性，因此南二高新市交流道特定區的開發，採取本研究之浮動開發方式來模擬運作，評選出四處浮動區位來協商開發。

　　為了解專家學者對浮動開發方式之意見，本研究以層級分析法(AHP)來對浮動開發與協商作專家學者的問卷實證。首先對浮動開發及協商之特性與策略作出層級設計，選出三十位專家學者作答，其綜合結果如下：

　　1.浮動開發為較為公平的土地開發方式，而效率也能在整體運作下達到成果。

　　2.協商的運作應是可行且公平的，但效率的達成則較差，而法令制度的建立被視為運作上最重要的依據。

　　綜合以上之分析，本研究之結論及建議如下：

　　1.浮動開發先期作業長，應用上應及早規劃。

　　2.應有一套合理鑑價制度，使權益分配更合理。

　　3.應用於交流道特定區時，建議將交流道與特定區一同規劃浮動。

　　4.為使協商運作順利，應籌組公正的仲裁機構。

　　5.及早培養協商人才，以利協商的進行。

　　6.可建立政府間的協商管道，使中央與地方共享開發成果。

　　The land development led by the government often causes the issues of fairness and efficiency by inflexible development methods. The purpose of this thesis is to propose a new land development approach-floating development-to effectively solve the problems and achieve the goal of land development. This thesis takes the special district areas of the South Second Highway Interchange as examples to study the feasible of floating development.

　　First, this thesis considers the pros and cons of the domestic land development methods and compares with the function and goal of foreign flexible land development methods. Moreover, according to the Floating Zoning and the current environment, this thesis offers a two-stage floating development and an operating process, explains the floating development mode by monopoly theory and rational expectation theory, examines its characteristic and limitation, and compares with current land development methods.

　　In addition, the floating development approach bases on negotiation, therefore, this thesis examines the definition and the aim of negotiation. Moreover, this thesis focuses on land developing negotiation to analyze its pros and cons and operation and to build the negotiating mode of a two-stage floating development approach.

　　Applying the floating development to the interchange special district area, this thesis first analyzes the characteristics of the interchange special district areas of the Chug-Shane Highway, and finds that it is not successful resulted from the irrational land development. Therefore, this thesis takes Shin-Shih interchange special district area of the South Second Highway for example to examine the floating development method and to screen out four floating locations for development and negotiation.

　　In order to study the experts' and scholars' opinions on floating development method, this thesis adopts the AHP (Analysis Hierarchy Process) to survey the floating development and negotiation. This thesis designs goals and strategies of floating development and negotiation, and selects 30 experts and scholars to answer an AHP questionnaire. The results are as follows:

　　1.The floating development is fair and more effective.

　　2.The operation of negotiation is workable and fair, however, is lack of efficiency. Establishing disagrees and regulations is regarded as the most important reference of operation.

　　According to the above analyses, this thesis concludes and suggests:

　　1.It takes long time to prepare the floating development, therefore, it should be designed and planned earlier before applying.

　　2.We should develop a reasonable evaluating system to make the distribution of benefits more reasonable.

　　3.When applying floating development to the interchange special district area, it would be better to plan floating interchanges and floating special district areas together.

　　4.To operate negotiation fluently, establishing appropriate arbitration institution is suggested.

　　5.Cultivating professional negotiators earlier will be helpful to negotiation process.

　　6.Building the negotiation channel among governments will benefit both central and local governments.
