中國加入WTO之後，大陸經濟體制轉型。從早期的計劃經濟到現在的市場經濟。投資政策也趨向「引進來，走出去」，此外，有鑑於大陸具有廉價的勞工和市場潛力，外資紛紛從所謂綠地投資或藉由合格境外投資者等間接投資方式轉為合併或收購為主的直接投資為取向。然而，面對上市公司因為涉及中國大陸特有的「股權分置」現象，使外資於併購上有一定困難度。再者，中國大陸特有的「民族情感」因素，使行政機關常常藉由「國家安全」等不確定法律概念而否准外資併購。 本文主要針對外資併購上市公司經常適用之法令作整合及研究，並論及外資併購上常運用之契約條款進行分析。此外，針對外資併購常遇到之問題提出淺見並針對外資併購中債權人及中小股東之保護提出論述，以供外資於併購中如何在外資獲利及中小股東權益保障獲得平衡點。 / Since China has become the members of WTO, the economic structure has transformed.
