本文從新古典現實主義研究民進黨萊豬開放政策。研究發現： 1. 民進黨政府萊豬開放受到權力差距影響；2. 民進黨政府萊豬議題認 知轉變受到權力差距影響；3. 民進黨萊豬開放受到民進黨政府萊豬議 題認知轉變影響；4. 民進黨政府萊豬議題認知轉變是中介變數；5. 萊 豬議題爭議程度是調節變數，而議題爭議程度冷清則有利民進黨政府 開放萊豬。本文根據結果建立一個完整模型，以期望幫助對萊豬議題 感興趣者，能夠全面性了解權力差距、議題認知、議題爭議程度與政 策執行，對民進黨政府開放萊豬政策之關係。

This study examines the DPP’s U.S. pork open policy from neoclassical realism. The study finds that: (1) the DPP government’s U.S. pork open policy is affected by the power distance; (2) the cognitive change of the DPP’s U.S. pork issue is affected by the power distance; (3) the DPP’s U.S. pork open policy is affected by the cognitive change of the DPP’s U.S. pork issue; (4) the cognitive change of the DPP’s U.S. pork issue is a mediator; (5) The degree of dispute over the U.S. pork issue is a moderator and the dispute level of the issue is cooler, the more favorable for the DPP to implement the U.S. pork open policy. Based on the results, a complete model was developed to help those who are interested in the U.S. pork issue to comprehensively understand the relationship among power distance, issue cognition, the degree of dispute over the issue and policy implementation on the DPP’s U.S. pork open policy
