政府採購法第三十六條第一項規定，機關辦理採購，得規定投標廠商之基本資格。於同條第二項又規定，特殊或巨額之採購，須由具有相當經驗、實績、人力、財力、設備等之廠商始能擔任者，得另規定投標廠商之特定資格。然而，為了避免不當限制競爭而採用「特殊或巨額門檻」之方式，限制達到門檻之採購案始得設定特定資格，造成資格設定之斷層，並使機關無法依照該條第一項依招標標的之特性以及實際需求，設定投標廠商資格，以致於無法達成保障採購品質之目的；故以避免不當限制競爭為目的所採用之限制方式，不可違悖設定投標廠商資格之目的。本研究以此觀點出發，收集國內外資格設定相關文獻，整理分析後發現，以市場調查方式，收集廠商資料作為設定資格內容與門檻之參考依據，不但可降低資訊不對稱情形，對採購之負面影響，更是避免不當限制競爭之最好方式；因此，本研究提出一套建議修正方式，取消特殊或巨額門檻以及限制資格門檻之限制，以市場調查作為設定資格之必要程序，讓投標廠商資格設定回歸案件實際需求，同時能達到避免不當限制競爭之目的。 According to Article 36 of the Government Procurement Act, a procuring entity may prescribe basic qualifications of tenderers based upon actual needs. From the same article, for special procurement or huge amount procurement which must be contracted to suppliers with substantial experience, performance record, manpower, financial capability, equipment, etc., specific qualifications for tenderers may be prescribed. It means that only for special procurement or huge amount procurement, an entity can prescribe specific qualifications of tenderers. The purpose of setting the thresholds of special or huge amount procurement is to prevent an entity restrains competition unduly. Therefore, a gap of qualification appears in the provision, and which might force an entity giving up prescribing qualifications of tenderers based upon the characteristics of the procurement and actual needs for procurements not meeting the thresholds. This contradiction within the article may lead to unguaranteed quality of procurement. In this research, according to the foreign literature referenced, the best way to prevent an entity restraining competition unduly is to prescribe qualifications of tenderers in accordance with market survey for potential tenderers upon work experience, financial capability, etc. It is proposed in this study to make some revision on Article 36 and other related regulations to delete the thresholds of special procurement and huge amount procurement to allow the procuring entity establishing qualification for tenderers based on actual needs and practical market survey. This will also serve the purpose of preventing the entity to restrain competition unduly.
