現今企業正面臨著國際化與自由化的衝擊，市場競爭激烈，企業為求競爭優勢，使經營更具效率及獲利性，必然會不斷追求成長，而購併則是企業追求快速成長有效的策略方式之一。企業購併系一項策略工具，它是產業發展的重要手段而非目的，是具有一定風險且流程複雜的商業行為。因此，事前審慎研擬策略、評估規劃及購併後的有效整合以實現績效提昇達成購併綜效就顯得非常重要。　故本研究透過產業分析及個案研究之實證，輔以專家深度訪談，找出企業購併成功的關鍵因素，對要進行購併交易活動的企業予以建議適當之購併策略。　 　本研究之研究結果得出下列結論： 一、並非所有公司都適合採用購併策略，因為若要採行購併策略，公司勢必投入相當多的資源，且承擔一定程度的風險，對於資源相對不足的中小型企業，購併策略不見得適合。由此可知，不同規模的企業適合採行的策略也大相逕庭。 二、經由事先的審慎的估計，確認自身優勢及不足的地方，決定採行購併策略後， 除了尋找最佳購併標的外，更應該成立專業的購併團隊，研擬詳盡可行的合併步驟，積極執行購併後的整合工作。 三、進行內部整合，使企業的財務、會計及營運體質趨於健全且透明度提高，進一步提昇公司價值，如此一來，不論是處於購併他人還是被他人購併的立場下，均能順利進行，綜而言之，購併與整合是相輔相成的策略，缺一不可。
