關於上游反傾銷控訴對下游廠商之影響，目前臺灣仍缺乏一整體性之研究。本研究以1992～2011年21件臺灣反傾銷案例共83家廠商為研究對象，其中包括了18種不同的下游產業。研究結果指出，臺灣反傾銷控訴對國內下游廠商不一定都是負面影響，平均而言，反而使下游廠商超額報酬增加約2%。而影響下游廠商超額報酬之主要因素為產業特性，例如，市場結構、涉案產品進口滲透率及關稅稅率等。

In Taiwan, there is not yet sufficient and integrated research on how antidumping suits filed by upstream vendors impact the downstream industries. In this paper, we have studied a total of 21 antidumping cases in Taiwan during the period of 1992 to 2011, involving 83 companies from 18 different downstream industries. The result suggests that the antidumping suits in Taiwan may not necessarily lead to negative influences on the downstream industries in the country. Rather, they have resulted in, on average, a 2% increase in the abnormal return of the downstream industries. The main factors influencing the abnormal returns are industry-specific, for example, the market structure, the import penetration ratio of the products in question, and the tariff rate, among others.
