本文從歐盟競爭法上關於事業結合之當規則出發,論述其適用之疑義與規範漏洞,並討論實務上之改革與學說上之改進建議。舊規則之最大爭議,在於關於審查基準之「控制地位」標準,並未能妥善規範事業結合所有問題。而二○○四年新修正之事業結合新規則,則改採美國之SLC標準,並相當程度上彌補了前述漏洞,唯其依舊遺留部份問題尚待進一步發展。
This article aims to c1arify how the normative gaps of old EC Merger Regulation could be resolved by the practice, the doctrine and the 2004 revision. The major dispute in the old Regulation is the standard of Dominance Test, by which some issues in the Merger control could not be properly regulated. Thus, the New 2004 Merger Regulation resorts to the American SLC Test, by which some normative gaps could be resolved. Nevertheless, it remains some ambiguities in the revision to be clarified.
