近年來隨著台灣威權體制的轉型，使得國內有關軍文關係以及軍方角色的議題，逐漸成為學術上關注與討論的焦點。然而，現有的研究大多是以西方的理論來解釋台灣的現象，並且是屬於國家層級以及制度面的研究，卻很少針對軍方在地方政治、經濟與社會所其有的角色作深入的探討。因此，本文試圖採取由下而上的探討方式去考察地方層級的軍文關係，並且採用歷史結構的研究途徑，運用深度訪談的田野研究方法進行經驗資料的蒐集，並輔之以歷史文獻與官方統計資料的佐證，來分析1945年以來澎湖地區軍方角色之轉變。主要的研究發現是：何以軍方在澎湖地方的支配性角色會從1986年開始崩潰，同時又如何逐漸轉變為支援地方的新角色。

Issues of military-civilian relations in Taiwan have attracted the attention of scholars during Taiwan's democratization process. Existing literature have borrowed heavily from Western theories and were primarily focused on research at a national or institutional level. This paper proposes to take a bottom-up approach, to look at the relations through a case at the local level, Penghu County, and it will adopt a historical and structural approach, relying on fieldwork, in-depth interviews, past documents and official statistics. We will begin from the early stage of military presence on Penghu islands, and proceed to analyze the transition of military roles in Penghu since 1945. The primary findings include: why and how the military's domination of local politics in Penghu has collapsed since 1986, and how it has gradually taken up the role of aiding local development, a new role that has emerged since.
