目前臺灣仍缺乏反傾銷保護對臺灣廠商技術效率影響的系統性研究，本研究以臺灣1984～2010年所有包含上市公司的反傾銷控訴案例為研究對象，探討反傾銷相關事件對臺灣提控廠商技術效率之影響。研究結果指出，雖然平均而言反傾銷控訴對提控廠商技術效率有正面影響，但仍有約三成案例的實證結果是負面的。其中，對於低技術水準之提控廠商，反傾銷保護可使其技術效率有較大的改善，但這類廠商保護時間拉長後，卻反而會使其技術效率降低；同時，課徵反傾銷稅的時間拉長後，也會導致反效果。這些研究結果可提供政府在審理反傾銷控訴案件時做為參考。

Currently, Taiwan lacks a systematic study on the effect of anti-dumping protection on the technical efficiency of Taiwanese firms. As such, in this study, all cases of anti-dumping complaints of companies listed in Taiwan during 1984 and 2010 are used to investigate the effects of anti-dumping complaints on the technical efficiency of Taiwanese firms. Our research results indicate that, although the average effect of anti-dumping complaints has a positive impact on the technical efficiency of complaining firms, there are still negative results in 30% of cases. Among them, anti-dumping protections can lead to great improvements in the low-technology manufacturers. However, if the protection time for these manufacturers is prolonged, their technical efficiency declines. Additionally, if the duration of imposed anti-dumping duties increases, it could also have the opposite effect. These results can serve as a reference for the government when presiding over anti-dumping complaints.
