就法制面觀察，我國電信相關法制似已銜接GATS電信參考文件之基本電信服務監管架構原則。但近年來，外國電信業者對於我國電信服務產業競爭規範，多所質疑，我國應檢討相關競爭政策，以完全符合GATS之要求。此外，我國對於正在進行中之美墨關於電信服務產業競爭規範之爭議，應有高度注意，以確保我國未來在WTO多邊體制下之權益。 WTO架構下以特定服務部門為基礎之競爭規範，對於該特定產業之市場競爭秩序，有其正面實質意義。以電信參考文件為例，首先，將該文件納入額外承諾欄之WTO會員，必須在內國法制實現競爭之防護、網路互連合理化、以及普及服務義務透明化等競爭政策。再者，過去如美國有效競爭準則等雙邊機制，已被GATS電信參考文件所取代，使電信服務產業之競爭規範由雙邊模式轉移到多邊架構之下。 然而，近年相關貿易爭端也呈現了GATS電信參考文件之侷限性。競爭政策之國際化有其本質上之困難。本文針對「特定部門方式」之競爭規範，分析其可行性。在由管制規避與管制俘虜等論點切入後，本文認為，WTO應以整合角度處理競爭政策，提出一套全面的實體競爭規範，並強調在多邊架構下促進競爭政策對於國際貿易發展之整體貢獻。

　　　　　We have made significant progress in bringing our telecommunications laws and regulations into compliance with our commitments under the GATS. However, more work needs to be done to effectively prevent anticompetitive practices. Particular attention should be given to the ongoing dispute between the U.S. and Mexico being brought before the WTO. It is a good opportunity for the "Reference Paper" to actually go through the dispute resolution process so that some sort of precedent exists and we can obtain a surer understanding of what the actual meaning of the Reference paper. Most governments included commitments on regulatory disciplines based on a Reference Paper which defines competition safeguards, interconnection guarantees, licensing criteria, independence of regulators from operators, and other principles for the regulatory framework for basic telecommunications services. The U.S. ECO test, for example, has been modified by the 1997 Foreign Entry Order. The Reference Paper, therefore, is revolutionary. Domestic competition policies regarding telecommunications services are being multilateralized. This article discusses the limits of the sector-specific competition rules under GATS. Sectoral approaches can serve as a model for the future liberalization of other regulated industries. The sector-sepcific competition rules are, however, exposed to the risks of regulatory bypass and regulatory capture. Substantive competition principles should be applicable to all economic sectors under the WTO to enhance the integration of trade and competition rules in the multilateral framework.
