台灣在加入WTO後，我國必須履行WTO協商之承諾，調降各類產品之進口關稅，取消各類進口管制、削減境內補貼等貿易保護措施，而農產品更是協商削減之主要對象。國內農產品在未來勢必面對低價進口品的衝擊影響，如何在短時間內快速評估產業損失，值得政府相關單位多加重視。本研究運用美國國際貿易委員會所發展的商業政策分析系統（簡稱COMPAS模型）進行農產品產業損害認定之分析，探討特定農產品（高山梨為例）若停止適用關稅配額政策時，對產業所帶來的衝擊影響。我國為避免國外農產品大量進口，影響我農民權益，本研究以高山梨(Pears)於實施關稅配額進口制度作為研究對象，並蒐集其產業及國內市場狀況之相關資料，加以研析，利用COMPAS模型預測在取消相關保護措施後所可能帶來之衝擊影響，結果發現一旦政府相關保護措施的取消，高山梨之價格、產出帶來大幅度的負面影響，本研究結果可提供我國目前正在實施之23項「關稅配額」(Tariff-Rate Quota, TRQ)，其中更在15項實施特別防衛措施之產品推估其成本與收益評估指標，作為政府部門事先預為輔導開放及彌補損害之效益評估模型。

After joining WTO, however, our nation must commit to the terms specified by WTO, including lowering duties for imported products, lifting import restrictions, and reducing subsidies which are primarily focused on agricultural products. In this study, we use the Commerce Policy Analysis System (or "COMPAS" for short) developed by the International Trade Commission of the U.S. to assess the industrial losses seen in agricultural products and the impact on the industry if the needed tariff quota policies or SSG (Special Safeguard) for certain agricultural products (such as pear) are lifted. We have collected the related data on this industry and Taiwan's market for further analysis. The results of our study serve as references for the 23 tariff quotas that Taiwan is practicing, and 15 of them can serve as the references for determining the cost, benefits, and loses of products under SSG, allowing the government to provide needed support and compensations for the possible losses in advance.
