在競爭激烈的產業環境中，企業必須具有產品價值的創造能力，才能開發新產品以滿足顧客的需求。故本研究欲探討當企業宣告取得專利權、專利授權與代理權促使競爭優勢提升之資訊內涵。本研究以民國94年及95年宣告取得專利權、專利授權與代理權之公司，及依同產業及相似公司規模配對之公司組成研究樣本。首先以事件研究法探討宣告樣本是否能獲得正向報酬，並將樣本分為專利權、專利授權與代理權三組子樣本以觀察不同競爭優勢對報酬影響之程度是否有差異，最後再將專利權樣本分為發明專利與新型式專利兩組子樣本以瞭解不同種類專利權對報酬影響之程度是否有差異。實證結果如下：一、當企業宣告取得專利相關競爭優勢時，有正向報酬產生。但惟有當企業宣告取得專利授權與代理權時才能獲得顯著正報酬；二、企業宣告取得不同競爭優勢對報酬影響之程度有差異，企業宣告自行研發專利與取得專利授權所能獲得的報酬有顯著差異，宣告自行研發專利與取得代理權在事件宣告後的報酬有顯著差異，而宣告取得專利授權與代理權所能獲得的報酬則無論短期或長期皆無顯著差異；三、企業宣告取得發明專利或新型式專利，兩者所能獲得的報酬並無差異。 / In the keenly competitive environment、enterprises must have the abilities of product value creation to develop new products and to satisfy customers』 demand.
