多邊主義下帶動之「全球化」及區域主義下所帶動之「區域化」皆已成為現階段國際經貿發展的兩股重要潮流，透過洽簽自由貿易協定所達到之區域經濟整合，在區域內可消除絕大部份之關稅及非關稅貿易障礙，預計將有助於增進會員國間之貿易量，形成貿易創造效果，而或對於非會員國造成貿易轉向效果。故其將影響國際貿易的流向，國際資源的重分配，進而改變國際分工型態。 為瞭解區域經濟整合對於貿易流量的影響，本文首先將就區域經濟整合之定義與法源、區域經濟整合發展與現況、及台灣與各主要區域經濟整合之貿易概況進行概述。鑒於引力模型可有效的分析雙邊的貿易流量，本文針對該模型之相關文獻及實證歸納與整理，並利用引力模型，選擇全球六個重要區域經濟組織包括北美自由貿易區、歐盟、東協自由貿易區、南方共同市場、安地略集團及紐澳緊密關係協定等區域共計37個國家，以設定虛擬變數之方式實證1990年至2003年長達13年間各區域經濟整合的過程中，其對於區內會員國及對非屬會員國進、出口貿易流量之影響，特別是整合過程中對台灣是否產生貿易轉向之現象進行實證研究，並分析影響貿易流量之因素。 本實證研究發現影響二國間貿易流量的因素分別為出、進口國之國民生產毛額及人均國民生產毛額，以及距離。區域經濟整合具有明顯的貿易創造效果，而貿易轉向效果則隨經濟整合的緊密程度、區域內產業分工型態及與區域外國家出、進口結構及產業間相互競合程度不一而產生不同的影響。在上述六個區域經濟整合中，北美自由貿易區及南方共同市場對台灣產生貿易轉向的現象。本研究亦針對上述之結果與區域經濟整合實際進展現況進行交互分析。最後，本研究將就政策面及後續研究的方向提出建議，俾供參考。 / Globalization and regionalization have been the two main trends in international economic development in recent years. Already, many countries have signed Free Trade Agreements to achieve the goal of regional economic integration. This integration allows members of the region to virtually eliminate all tariff and non-tariff trade barriers and, as a result, increase trade volume between member countries. This phenomenon is called trade creation. On the other hand, trade volume between members of the region and non-member may decrease, a phenomenon called trade diversion. All of this will affect international trade flows, the allocation of international resources and change the pattern of the international industrial division. In order to learn how regional economic integration influences trade flows, this paper deals first with the definition and regulation under the GATT of regional trade agreements, the present situation and the development of regional economic integration. We also examine the current state of import and export trade between Taiwan and the main regional economies in the world. This paper reviews the relevant literature on the gravity model, a model that can effectively analyze trade flows between two countries, then proceeds to use this model with NAFTA, EU, AFTA, MERCOSUR, ANDEAN Community, and CER (Closer Economic Relationship between the Australia and New Zealand) as regional dummies. This allows us to test alterations in trade flows between members and other members as well as between members and non-members (especially Taiwan) in these six regional trade blocs for the 13 years between 1990 and 2003. This model also analyzes the main factors affecting trade flows. We find first that the main factors influencing trade flows between two countries are the GDP and per capita GDP of the importer and exporter as well as distance. Secondly, while regional economic integration clearly brings with it trade creation, the degree of trade diversion is affected by such factors as the degree of regional economic integration, the pattern of industrial division in the region, the structure of imports from and exports to non-member countries and the level of competition and cooperation in various sectors. The empirical evidence shows that NAFTA and Mercosur have resulted in trade diversion away from Taiwan. Based on our findings, we offer policy suggestions and suggestions for further research.

不論是反全球化或是支持全球化，我們都無法否認，全球化已經是一個現在進行式。另外一個與全球化一樣逐步成長的乃是市場經濟體制，市場經濟體制植基於開放競爭有助於資源合理分配的觀念，而全球化則擴大了資源分配的範圍。然而，全球化和市場經濟體制的發達，貿易壁壘的消除，也帶動跨國界限制競爭活動的發展，反托拉斯不再是單純的國內問題，而是國際問題。 國際反托拉斯所帶來的問題大致可分為下述兩種，一是阻礙國際貿易的發展，二是因為各國不同的反托拉斯標準造成國際緊張以及企業成本。第一類問題可以細分為下述幾種情況：1. 國際卡特爾破壞市場競爭機制以及消費者福祉； 2. 跨國公司在全球濫用獨占力，影響國際競爭秩序和消費者福祉；3. 競爭法的缺乏以及競爭法的不力執行構成市場進入障礙。第二類問題亦可以細分為下屬幾種情況：1. 國際合併的多國標準造成企業的額外成本，不利國際合併之進行，並造成國際緊張；2. 國與國間產業政策以及競爭政策的衝突。 面對上述這些跨國性的反托拉斯問題，各界紛紛提出競爭法調和的呼籲，此議題近來在各國際組織也漸獲重視。事實上為了處理國外限制競爭行為對國內所產生的影響，以保護本國利益，國內法方面已有所謂的「域外適用（extraterritorial application）」對策產生。但是競爭法的域外適用並無法全然解決現時國際限制競爭行為所帶來的問題，反而還帶來了新的問題，並造成國際緊張。為了在國際案件有效執行反托拉斯法，不論是在卡特爾案件或是獨占力濫用案件，各國競爭法主管機關互相合作與協調都是不可或缺的。至於將競爭法提升至國際法層次，避免國家以非關稅措施破壞自由貿易制度，似乎也有需要。 本文目的在於藉著對競爭法調和現況的瞭解和其成就之分析來尋求目前全球化時代，貿易自由化時代下跨國限制競爭問題的解決之道。 全文一共分為六章，第一章為緒論，為本論文做出開端，闡明全球化時代國際競爭秩序的問題，並提出研究範圍與目的。 第二章研究關於國際競爭秩序的雙邊條約，著眼於美國和歐盟，澳洲和紐西蘭，以及我國和世界各國所訂立的條約。討論範圍為該些雙邊關係所建立之合作內容，其具體成效，成功失敗之因素，以及可供世界各國借鏡之處。台灣部分則著眼於我國目前現狀之檢討，和未來走向之研究。 第三章為從事競爭法調和的區域性國際組織，研究範圍包括歐盟、APEC以及NAFTA。其中APEC所從事的活動較近於政策性的調和，屬於競爭政策的宣導；NAFTA則進一步具有競爭法的實體規範；歐盟不但具有實體規範，並具有一套全球獨步的競爭法執行架構。 第四章為國際組織，將討論UN, WTO和OECD在國際競爭法的發展。UN基本上雖為政治組織，但是對於競爭議題也相當重視；WTO部分則將討論目前競爭議題在WTO體系的進展，並進一步討論WTO進行國際競爭法調和工作的可行性和不可行性；OECD對於競爭議題也一直相當重視，本文將探討OECD在競爭議題方面的研究成果。 第五章為全球性的競爭法規範，討論的範圍有UNCTAD所提出的「管制限制性商業行為的一套多邊協議的公平原則和規則（Set of Multilaterally Agreed Equitable Principles and Rules for the Control of Restrictive Business Practices）」以及DIAC。這兩套全球性的競爭法不但都具有實體規範也都提出一套制度性規範，雖然兩者都未能成為具有拘束力的國際競爭法，但是其所提出的實體規範內容和架構設計仍值得我們做進一步的研究。「管制限制性商業行為的一套多邊協議的公平原則和規則」本身是以聯大決議的形式呈現，因此在某一角度而言，「管制限制性商業行為的一套多邊協議的公平原則和規則」並未失敗，然而DIAC原本乃是預定成為WTO的附件之一，唯最後這樣的理想並未實現，因此我們有必要去問，DIAC的失敗因素為何？是基於其實體內容的設計問題，或是制度面的設計問題？或者是因為其他的外在因素？ 最後，在第六章的結論，本文將試圖分析各種競爭法調和方式的利弊得失，並且提出建議。 / Some people oppose globalization, while others support globalization. However, it is undeniable that globalization is an on-going trend. Another on-going trend is market-oriented economy structure. The structure of market-oriented economy bases on the theory that competition contributes to reasonable allocation of resource. On the other hand, globalization expands the scope of the allocation of resources. However, the proliferation of globalization and the structure of market-oriented economy and the elimination of trade barriers also promote the development of transnational anticompetitive activities. Antitrust is no more a pure domestic issue, it is also an international issue nowadays. International antitrust problems could be divided into two parts. First, the international antitrust activities hinder the development of international trade. Second, different antitrust standards of each country cause international tense situation and increase enterprises’ cost. First situation contains following aspects: 1. International cartels ruin market competition system and welfare of consumers. 2. Transnational companies abuse their dominant power all globally and affect international competition order and consumers’ welfare. 3. Absence of competition law and unenforcement of it constitute market entrance obstacles. Second situation also contains following aspects: 1.Different standards of international mergers bring many results, such as increasing enterprises’ extra cost, hindering the proceedings of international mergers, and causing international tensions. 2. The conflict between industry policy and competition policy of countries. Facing those transnational antitrust problems, the issue of the harmonization of competition law has been raised. This issue is drawing more and more attention in several international organizations day by day. In fact, to deal with the domestic effect of abroad anticompetitive activities to protect national interest, the theory “extraterritorial application” of domestic law has been raised. However, the extraterritorial application of domestic law is unable to solve all the problems that the international anticompetitive activities have brought. Furthermore, it has also made new problems and caused international tensions. To enforce antitrust law effectively in international cases, cooperation and coordination between national competition agencies are unavoidable. In addition, bringing antitrust law up to international law level and avoiding nations ruin free trade system by non-tariff strategy seem also be needed. The main purpose of this essay is to understand and analysis the current situation of the harmonization of competition law and to find out the solution of transnational competition problems in the era of globalization and the era of free-trade. This essay has been divided into 6 chapters. The first chapter is the introduction, which illustrates the international competition problems in the era of globalization and brings out the studying scope and purpose of this essay. The second chapter talks about international competition bilateral treaties between U.S. and E.U., Australia and New Zealand, Taiwan and other countries. The discussing scope contains the cooperation content which was set up by the bilateral treaty, its concrete result, and the reasons of its failure or success. As for Taiwan, this essay focuses on the review of its current situation and where its future is. The third chapter talks about regional international organizations which involve in the harmonization of competition law, such as E.U., APEC and NAFTA. APEC’s activities are more closer to the harmonization of policies, which promote competition activities. NAFTA has substantial competition regulations. E.U. not only has substantial regulations but also has the first set of enforcement system of international competition law in the world. The forth chapter is international organization, which talks about the development of international competition law in U.N., WTO and OECD. Although basically U.N. is a political organization, it also highly emphasizes competition issues. In addition, this chapter talks about the development of competition issues in the WTO system and the possibilities of promoting the harmonization of international competition law in WTO. Additionally, OECD also emphasizes competition issues very much. This chapter also talks about the study result of OECD in the competition issues. The fifth chapter is the global competition regulations, which contains “Set of Multilaterally Agreed Equitable Principles and Rules for the Control of Restrictive Business Practices” of UNCTAD and “ Draft International Antitrust Code”. Both of the global competition laws contain substantial regulations and the design of enforcement systems. Although both of them ended up in unrestrictive regulations, they also deserve further research. “Set of Multilaterally Agreed Equitable Principles and Rules for the Control of Restrictive Business Practices” was brought out with the form of UN General Assembly Resolution, but it is successful in some aspect. DIAC was meant to be an Annex of WTO originally. However this idea was not realized at the end. Why DIAC failed? Was it because of the design of its substantial content or the design of the enforcement structure or other outside factors? At last, this essay will analysis the shortages and advantages of all kinds of the harmonization of competition law and bring out recommendations in the conclusion of chapter 6.
