公平交易法與消費者保護法是我國由管制經濟進步到市場經濟的二個劃時代的立 法，前者著重維護競爭秩序之自由及公平，後者則著重保護消費者。二者無論在立法目的、 規範對象、主管機關乃至彼此法條之解釋適用上，均有極密切的互動關係，本文之研究即以 橫向之綜合比較，指出其間之異同以及可以相互映照之處，希望有助於改善分別研究不足之 處。

　　　　　Two years after the enactment of the Fair Trade Law (FTL) the Consumer Protection Law (CPL) was adopted on Jan. 10, 1994. This paper compares the two laws with respect to their purposes, subject matters, administrative authorities, and mutual influences. It comes to the conclusions that: 1. FTL with its Fair Trade Commission (FTC) aims to protect the market competition and competitors in the first place, and only secondarily to ensure an environment that is beneficial to the consumers as a whole, while CPL pursues the direct protection of the comsumers. 2. FTL with its administrative instruments regulates transactions in the market place that are not to satisfy consumer needs only. On the contrary CPL regulates the transactions that are made by the consumers. 3. FTC is an independent legal person under public law with full authority to investigate and make administrative acts, while the Consumer Protection Commission (CPC) is only a cabinet internal consulting body, which can neither investigate nor make administrative acts. 4. According to § 24 FTL deceptive or obviously unfair acts are forbidden. Some regulations from the CPL can contribute to the finding of deception and unfairness, for example paragraphs 13, 18, 21, 24, 25 (deception), 12, 20 and 10 (unfainess). § 24 FTL in return helps to concretize some regulations of CPL, like § 4 and § 22.
