本研究以探討我國武器獲得方式之影響因素及其傾向為目的，全文從武器系統之觀點出發，將武器獲得方式區分為「國外採購」與「研發自製」二類，於透過文獻論述與專家訪談後，彙整影響武器獲得方式之因素與變項，作為問卷設計與調查之基礎。研究中，首先進行探索性因素分析並萃取十二項影響因素，然後再經由變異數分析發現「國家經濟與工業發展」、「科技能力」、「建立外交與戰略關係」及「決策受組織主導程度」等四個因素，在我國武器獲得方式決策上具有顯著的差異，最後，再利用區別分析檢視此四個影響因素。研究結論發現，若我國武器獲得方式較重視「國家經濟與工業發展」及「科技能力」時，則將傾向於「研發自製」 ；反之，若較重視「建立外交與戰略關係」及「決策受組織主導程度」時，則傾向「國外採購」。

This research tries to explore the factors that affect the acquisition process of the Republic of China by dividing the arms acquisition into Foreign Purchase and In-House R&D. By doing so, this paper starts from interviewing the experts and drawing some factors from the literatures so that the questionnaire can be established. Next, the 12 factors had been acquired by carrying out the exploratory research and divided into four groups after conducting the variance analysis, which has significant level on the acquisition policy of Republic of China. The conclusions are: if the government policy tends to focus on national economic and industrial development and the building up of the technology capability domestically, then the acquisitions in practice would be more cline to In-House R&D. However, if the government policy attempts to establish the foreign relationships and somehow the decision is controlled by the top-management bureaucracy, then the acquisitions in practice would be more cline to Foreign Procurement.
