本研究從觀察台灣基改食品政策領域的特色著手，發覺其大都與國際規範息息相關，因而促使我們去關注國際組織與跨國行動者的影響力所在。本文從全球治理的角度，探討國際政府間組織、跨國企業與國際非政府組織，如何影響台灣的基因改造食品管制政策的制定？透過全球治理文獻的檢視，本文指出主要的政策影響途徑、主要的行動者、基因改造食品的領域現況，從而提出兩大有待實證的假設，並透過文獻分析與深度訪談方法，進行實證研究，同時以政治經濟學的觀點對研究結果提出解釋，包括何以台灣主動且自願遵守國際規範，何以美國政府及其跨國企業在基因改造食品議題上緊密攜手合作，何以歐盟緊抓預防原則不放，因為背後都牽涉到龐大的經濟利益；本研究也指出由於台灣政經結構的限制，以至於必須有所抉擇，例如不採歐盟預防原則係因有政策執行上的困難，由於我國是大宗穀物進口依賴度相當高的國家，如果動輒以預防原則而又無充分科學證據顯示其可能危害人體或環境，進而拒絕基因改造食品的進口，恐易遭致進口國（主要是美國）的貿易抵制或報復，而我國是經不起這種對抗與打擊的；更何況美國是生技技術產業發展的龍頭，我國近年來汲汲於發展生技產業，都以美國的發展模式及管理制度為主要參考對象。此外，本研究中的案例一與案例二都是基於共同利益而利用既有的網絡，由跨國企業帶頭作為主體行動者，並聯合國內公會、協會與廠商進行Bachrach and Baratz（1970）所謂的「第二面向權力的運用」，將法案封殺於進入決策之前，使之無法進入一讀程序。最後，國際非政府組織在本個案中扮演的是一個諮詢顧問的角色，必須由國內民間團體主動與其聯繫進行資訊交流，雙方才會有所互動，相對而言，反而是國內民間團體對政策制訂過程具有一定的影響力。

Observing from the characteristics of the Genetically Modified（GM） foods regulatory policy in Taiwan, we find that they are closely related to international norms. This leads us to begin to concern with international organizations and transnational actors’ influences. From global governance perspective, this study explores how International Governmental Organizations（IGOs）, Transnational Corporations and International Non-Governmental Organizations （INGOs） use their influences to affect domestic genetically modified foods regulatory policy in Taiwan. Drawing from the relevant literature about global governance and GM foods regulation and from in-depth interview data, we point out main actors, significant policy influential approaches and propose two major hypotheses to be tested. We argue that the political economy perspective can explain why Taiwanese government voluntarily and positively conform to international regulations, for what reason American government and its transnational corporations keep close collaboration on the GM foods issue, and for what purpose the European Union grasps firmly the precautionary approach, as these political actions are tightly related to tremendous national or private economic gains and interests. This study also indicates that it is because of the special features of the Taiwanese political economic structure that constraints Taiwanese government not to adopt European Union’s precautionary approach. Taiwan is a country that being highly dependent upon importing a large shipment of crops from the Unites States annually. Besides both countries have close political and economic relationship. If applying precautionary approach against U.S. without sufficient evidence to show that GM foods will damage the human body or natural environment, the result for Taiwanese government to refuse to import GM foods might generate U.S. trade retaliation. Under the circumstances, Taiwan cannot afford to strike a blow against U.S., not to mention that the latter is a leader of the biotechnology industry. As Taiwan is anxious to develop biotechnology industry recently, it all refers to U.S. for its development model and management system. Moreover, case I and II demonstrate that transnational corporations, being the main actor to align with trade federation, association and firms, utilize the existing networks and the so called ‘second face of power’ to block bills become law. Finally, INGOs play only as a consultant role in this case. Both INGOs and domestic environmental groups can exchange their information only under the condition that the latter takes the initiative in maintaining communications with the former. In contrast, it is the domestic environmental groups that have direct impact upon GM foods regulatory decision-making in Taiwan.
