摘要
本篇文章主要談論於代理人與被代理人間利益衝突之問題，透過對於我國實務與學說見解，與外國之立法例為參考，針對「代理人外部關係下之利益衝突」與「代理人於內部關係與外部關係之利益衝突差異」二議題為深究。 於現代社會中，代理制度於經濟活動中扮演著不可或缺之腳色，倘被代理人透過代理人取得利益時，便同時須面臨一項風險，便係代理人利用其地位，為自己或是第三人謀取利益，致被代理人受有損害，此等風險得透過法律規範避免其發生。 於我國法之下，於代理關係中，關於利益衝突之部分，具有自己代理與雙方代理之規範，隨時代更迭，原本之構成要件與例外是否足以達成立法目的之要求？本文以「利益衝突」為核心概念，針對構成要件與例外規範之妥適性，重新進行檢驗，此外，利益衝突係屬於一抽象概念，其內涵又應包括何種情形，亦屬本文欲探討之主題。 另一方面，於內部關係（即原因基礎關係）中，我國法並無如同英美法系中具有忠實義務之概念，而此等概念於我國法之下是否有存之必要？本文認為，於面對代理人利益衝突之問題，蓋因外部關係與內部關係各有其不同之功能，故不僅應自外部關係為規範，亦須自內部關係避免代理人之利益衝突行為。隨著情況不同，於制度上則應對著不同之法律效果，如此方能使我國法下關於利益衝突之體制更為完整。

This paper deals with the conflict of interest between agents and principals, and emphasizes on "the conflict of interest in external relation" and "the different of the conflict of interest in the external relation and in the internal relation", by examining and analyzing the foreign legislation and the practice and theory in Taiwan. In modern society, Agency System plays an important role in business activities. When a principle uses an agent to obtain benefits, he must take a risk, that the agent uses his Status to make profit for his own interest or the third party’s interest, and therefore leads to principle's damages. Such risks can be avoided through the designs and patterns of legal norms. There is a rule concerning the conflict of interest in Republic of China (R.O.C., or Taiwan) law. In the civil code of the R.O.C, Article 106 [hereinafter Article 106] prohibits the self-dealing and dual agent. With the progress of the times, we wonder whether the rule still satisfies its original legislative purpose. As a result, this paper reviews the appropriateness of the constituent elements and the exceptions of Article 106. Moreover, “Conflicts of interest” is an abstract concept. In what circumstances can we apply to the concept, is also the subject the paper want to analyze. On the other hand, unlike the concept of “duty of loyalty” in Common law, should Civil Law in Taiwan also adopt the concept is one of the significant issues in this paper. The external relation and the internal relation have different functions, so the paper argues that the problem arising from the conflict of interest should be restricted by the external relation and the internal relation. Especially, there are more legislative types concerning the internal relation, which can be applied in different circumstances and cases. Consequently, the system of Taiwan law concerning principal-agent problems will be more complete than status quo.
