有鑑於中共對我軍事壓力日增，我國防預算呈現年年成長趨勢，然而相較中共的國防預算，兩者相差比例懸殊，在國防預算有限的情況下，國軍將非機敏性核心能量裝備維修委由民間廠商執行，妥善運用民間企業資源，加速料件獲補效率與裝備修復時效，故委外合約管理與執行成效攸關裝備妥善與戰力支援的重要關鍵。而為充分瞭解國軍通用裝備委商保修能量與維持裝備妥善情況，本研究具體找出保修作業與保修裝備在委商執行維修成效的差異，且分析委商契約規範對於各項通用裝備保修績效的影響，如此才能具體掌握委商保修作業與委商契約規範的管理成效。結果證實保修作業方式、裝備的類型、規格、用途、功能及價位其委商保修績效具有顯著差異，而合約核定契約的權責單位、契約廠商的型態、行業、規模及契約規範的維修時限對於委商保修績效也具有顯著不同，最後驗證委商契約規範確實具有干擾效果，國軍通用裝備的保修績效確實會因委商契約規範而有所差異，因此，後勤維修可依不同類型裝備訂定廠商資格並制定適宜契約規範，以提高委商保修品質與執行成效。

In view of the increasing military pressure by the CCP and under the trend of shrinking defense budget, the national army will commission the maintenance of insensitive core equipment by private manufacturers. In this way we will use private enterprise resources properly. We can accelerate the replenishment efficiency of materials and the timeliness of equipment repair. Therefore, the performance of outsourcing contract management and execution is critical to proper equipment and combat capability support. In order to we understand the maintenance capability of outsourcing for military common equipment and the situation of maintain proper equipment. This study will specifically find out the difference of outsourcing maintenance performance for maintenance operation and military common equipment. We will analysis the effect of maintenance performance for military common equipment on outsourcing contract specification. In this way we can grasp the management performance of outsourcing maintenance operation and contract specifications. The evidences indicate that the maintenance performance of outsourcing has significant differences with the equipment category, specification, application, function and price. We also find the maintenance performance have significant differences with contract authorization, contractor type, contractor industry, contractor scale and maintenance time limit specified in the contract. Indeed, outsourcing contracts have moderation effect. The maintenance equipment caused by different maintenance performance will vary depending on outsourcing contracts. The result can provide reference that conduct logistics outsourcing to meet contractor qualification. That will increase outsourcing quality, and maintenance performance.
