我國訂有「行政法人採購作業規章訂定參考原則」,以使監督機關及行政法人訂定採購作業規章有所依循,在確保採購程序符合公平、公開原則下,達成行政法人公共任務及營運之目標,然而實務運作時仍有許多需要改善之處,尤其是複雜的工程採購。本研究透過公開資訊管道,收集並分析行政法人採購制度共通性問題,並以中科院工程採購制度為例,深入分析中科院工程採購契約與工程會工程採購契約範本之差異,及司法院工程訴訟判決案例,進而分析目前制度存在的問題,並提出改善建議以降低或避免肇生履約爭議。期待本研究已綜整各行政法人採購制度共同性問題及中科院工程採購制度存在的問題,可用以協助解決目前行政法人在工程採購制度之不足,並提供後續研究的方向與建議。;Taiwan government has issued the “Reference Principles for the Establishment of Administrative Corporation Procurement Regulation” to guide supervisory agencies and administrative corporations in setting their own procurement regulations. These principles ensure that the procurement procedures adhere to fairness and transparency, achieving the goals of the administrative corporations’ public missions and efficiency operations. However, there are still many areas for improvement in practical operations, especially in complex construction procurement. This study collects and analyzes common issues in the procurement systems of administrative corporations through publicly available information. Using the construction procurement system of the National Chung-Shan Institute of Science and Technology (NCSIST) as an example, the study further analyzes the differences between NCSIST’s construction procurement contracts and the Public Construction Commission’s standard construction procurement contract templates, as well as the litigation cases related to construction procurement. This study has examined the existing problems in the current system and proposes improvement suggestions to reduce or avoid performance disputes. It is hoped that this study, which summarizes the common issues in the procurement systems of various administrative corporations and the specific problems in NCSIST’s construction procurement system, can help address the current deficiencies in the construction procurement systems of administrative corporations and provide directions and suggestions for future research
