因近年來政府公務預算逐年減少，加上武器市場與戰爭形態的轉型，已對國内國防 工業產生大幅變革，國軍如何在有限資源内，充分運用預算，改善國軍採購人員專業素 質，強化競爭能力，已是刻不容緩的問題。本研究利用LISREL因果關係模式，研究組 織福利因素、環境因素與周邊支持性因素，對國軍採購人員外派績效的潛在影響。研究 樣本爲曾經因軍事採購而接受外派任務的專業人員，計獲得160份有效問卷。研究結果 建議掌管國軍採購體系之主管當局，須注意與外派受訓人員績效有關幾項因素，如組織 越大、福利制度越好、升遷機會越多的組織，會正面影響外派人員適應；家人適應越好 以及對外派文化越好奇者，其外派適應性越好；但組織與主管越支持的外派人員，反而 對其外派適應性有負向的影響。

Due to the current governmental budget decreasing, the changes of weapon market and war style make reforms for defense industry and military institute. It is an essential problem to use the limited resource improving quality of military purchasing officers and competitive ability. This research uses LISREL to study the internal relationship of expatriate's organization welfare factors, context factors, supporting factors and expatriate performance for military purchasing officers. The samples of military purchasing officers should have the experience of expatriate. The total 160 effective questionnaires are collected. From the research result, we suggest that or-ganization should pay attention to the influence factors of expatriate adjustment and perfor-mance. The larger organization, the better welfare, the more promotion opportunities are positive to expatriate adjustment. The better adjustment of family and better culture novelty are posi-tive to expatriate adjustment. But the more organizational support and manager support are negative to expatriate adjustment.
