政府採購法於今(88)年5月27日生效實行，為我國重要之經濟管制法律。在此之前，公平交易法一直扮演著政府公共工程採購重要之行政管制工具。因此，在政府採購法施行之後，該如何與公平交易法調和適用，即為本文主要之目的。 本文之論點基礎在於：為何要將政府採購與私人操購為不同之對待，及應如何管制。通常為二種解決的方式:一種「內部監督」，如行政稽核；另一種是「外部監督」，即市場機制。為了保障投標者之權利，除了建立多種審查機制讓採購機關得以自行審查外，爭議處理制度同時提供投標者向政府機關表示異議機會。其目的均在於增進採購機關之效率及保護投標者之權利。其次，維護市場競爭秩序亦為法秩序之另一目的。因此，本文認為，公平交易委員會 (公平法之執法機關) 及公共工程委員會 (政府採購法之執法機關) 有必要互補其不足，由於政府採購法無法取代公平交易法之所有功能。 本文可大致分為三個部分，第一部分在於歸納及分析公平交易委員會對於政府採購之實務見解；第二部分在於分析公平交易法與政府操購法之互動關係；第三部分為本文之結論及建議。

　　　　　Graduate Student, Law school of National Taiwan University Procurement of public construction is the preeminent concern of Taiwan economic regulation. In May 27, 1999, "Government Procurement Act"(GPA)is going to be effective. Before that, " Fair Trade Law" (FTL)has been one of the most significant regulation of government procurement, especially in the disputes of public construction. Therefore, how to harmonize the relationship between GPA and FTL is the main purpose of this article. This article is based on the thinking of why we should treat public purchasing differently from private doing and how we could do for that. One method is internal control, as administrative monitor system; the other one is external control, as market monitor system. For redress to disgruntled offerors, we set up multiplicity of devices to permitting review within the purchasing agency itself. Besides, the 'bid protest' system also provides offerors with contest procurement decision of government agency. All of these, along with promote the efficiency of purchasing and protect the advantages of offerors, maintaining the competition order of market is one of the aims of the legal systems. The opinion of this article, therefore, considers it necessary for the cooperation of FTC and PCC (Public Construction Commission ) to reciprocate deficiency, since GPA can't totally replace of the function of FTL in the field of procurement. This article is simply divided into three parts. Part I is to epitomize and analysis the practices of Fair Trade Commission about procurement. Part II is to analysis the interaction of FTA and GPA. Part III is the conclusion of this article and provides some suggestion.
