本文以臺灣水泥產業為例，針對反傾銷案件成立後，其政策之效果進行分析，包括業者提訴反傾銷案件之影響效果及業界提訴反傾銷案件對整體產業經濟效果。此外，亦針對臺灣水泥產業之競爭力改變做一探討，尤其是在提訴反傾銷案件後，為臺灣水泥業者爭取到調適空間，進一步完成水平與垂直之產業整合，轉型為國際企業，提升產業競爭力。另因臺灣水泥業者違反公平交易法一案，有反傾銷稅之課徵是否與公平交易法所定義之公平競爭行為牴觸之疑慮，本文亦就反傾銷稅課徵後影響市場競爭及產業結構此議題作一探討。結果顯示，課徵反傾銷稅對水泥與熟料產業產生正面實質經濟效益（保護效果）；總體經濟效益則隨產業特性而產生不同效果。此外，反傾銷的課徵，由於事屬國外業者運用「不公平競爭行為」所採取的反制措施，因此，就精神上而言，與公平交易法所提倡之「公平競爭」原則相符合，應無違法之慮。

The paper attempts to analyze the effects of anti-dumpingmeasures on Taiwanese cement firms and the whole industry economics. Furthermore, it addresses the change in Taiwanese cement industry's competitiveness; especially upon the prosecution of dumping and the time it reword to affect the industry transition. The cement industry's violation of fair-trade law is also examined to evaluate whether it counterbalances the anti-dumping measure in effect. The results suggest that the anti-dumping measure is reworded with the material protective effect of the domestic cement industry; whereas mixed results were seen on the domestic economics as a whole. On the other hand, the establishment of the anti-dumping measure is the direct result of anti-trust cases brought by foreign firms; therefore, it conforms to the principles of fair-trade, and no violations were evident.
