本文探討歐盟電子通訊法制中對顯著市場力量之管制議題。首先就對電子通訊產品與服務市場加以界定,透過三項標準測試進行分析事前管制特定市場。其次,探討在特定市場中如何認定顯著市場力量,就顯著市場力量、共同優勢地位與獨占槓桿三種樣態,從競爭法之優勢地位案例與學說,配合電子通訊相關指令之規範,提出對顯著市場力量意義之具體描述。提出對顯著市場力量意義之具體描述。從共享權限與歐開法之補充原則,瞭解歐盟與會員國如何透過如Article 7程序進行合作,以處理顯著市場力量之管制。最後,我國電信法引進對「市場主導者」之不對稱管制,引發許多爭議與後續管制之困難。因此「通訊傳播管理法草案」中將顯著市場地位之管制革新列爲重點之一。本文將從以歐開顯著市場力量之立法例與學說之研究,對於顯著市場地位之意義與認定標準進行比較研究,並提出建言供國內參考。
This article examines several issues of significant market power (SMP) in EU electronic communications law. Firstly, it defines the relevant product and service markets within the electronic communications sector and analyzes ex ante regulation on specific markets by three-criteria test. Secondly, it discusses how to determine SMP in specific markets. By examining cases and theories related to SMP in competition law under the EU regulatory framework for electronic communications networks and services, it tries to clarify the concept of SMP in its three categories of dominance position, joint dominance, and monopoly leveraging respectively. By view of share competence and principle of subsidiary in EU law, it points out how member states and EU cooperate by applying the Article 7 procedure. Finally, it argues that the introduction of asymmetric regulation on ”Dominant Market Player” in the Telecommunication Act of Taiwan is controversial and problematic. Accordingly, the draft of ”Communications Regulator Act” proposed by the National Communications Commission has adopted several provisions in order to cope with the significant market position problems. As conclusion, it suggests lessons that may be learned from the EU electronic communications legislation and its experience.
