捷運車站的聯合開發通常是公部門和私地主之間的雙贏合作方式。各縣市聯合開發之合作機制的主要概念可能類似，但是影響因子的細節經常因地而異。本研究目的在於探討桃園捷運綠線沿線捷運車站聯合開發的影響因子並作出權重排序。先利用文獻回顧找出切合當今討論議題的聯合開發影響因子，再進行專家訪談，以確立所採用之聯合開發影響因子的相關細節及其鑑別度。經綜整得到層級分析法（AHP）調查問卷共六項主要構面，並包含二十一項關鍵性影響因子。發放調查問卷對象為聯合開發領域相關工作經驗至少5年以上的專家，回收有效問卷共11份。分析得到研究成果如下：（1）主要構面中以用地取得的權重為最高，佔總數的近30％;（2）綜合主要構面前三名之用地取得、規劃設計和權益分配的公平性，我們建議投資人和機關須著重其可行性並使相關內容更為完善;（3）關鍵性影響因子之協議價購金額的合理性、協議價購之民眾陳情、地主之聯開協商等項目是辦理捷運聯合開發成功的關鍵。調查結果符合桃園目前辦理中的捷運車站聯合開發的需求，並可提供作為投資人和機關辦理聯合開發之評估準則優先清單。 ;Joint development for massive rapid transit (MRT) area is usually a win-win collaboration way between public and private sectors. The collaboration mechanism may be similar for the major concept; however, details such as impact factors often vary significantly from place to place. The study objective is to explore and weight the impact factors for MRT joint development along the Taoyuan MRT green line. Literature review was initially carried out to discover factors that have been brought into discussion recently, followed by the expert interviews that determined the identifications and details for the adopted factors. There are 6 aspects with 21 factors that have been taken into consideration for the Analytic Hierarchy Process (AHP) questionnaire. The questionnaire was distributed to professionals with at least 5-year working experience regarding MRT joint development and there were 11 valid returns. The analysis resulted in contributable findings: (1) Aspect Land Acquisition has the highest weight, accounting for almost 30% of the total; (2) combing with the top three aspects of Land Acquisition, Planning, and Equity Redistribution, we suggest that practitioners and officials focus on how to make them more feasible and smooth; (3) Factors Contract Price, Civilian Demands, and Negotiations Terms are the keys to the success for MRT joint development. The findings match the needs for the ongoing MRT joint development in Taoyuan and provide practitioners and officials with the priorities of a to-do list.
