本研究主要目的在於結合市場導向與動態競爭的概念，並且進一步以察覺-動機-能力觀點探討廠商採取市場導向的競爭性行動對其績效的影響。透過台灣4大連鎖便利商店(即7-ELEVEN、全家、萊爾富與OK)為研究樣本，蒐集自知識贏家網路新聞資料庫2000年至2009年共計10年連鎖便利商店間的競爭新聞，並進一步將10年區分成40季進行分析，運用結構內容分析法(Structured Content Analysis)擷取連鎖便利商店1,477則新聞中之3,525則競爭行動加以分析。實證結果發現：(1) 市場導向競爭性行動對競爭者行動數目呈現正向關係；(2) 競爭者行動數目對焦點廠商績效呈現負向關係；(3) 市場成長性會強化市場導向競爭性行動與競爭者行動數目的正向關係；(4) 市場成長性會弱化競爭者行動數目與廠商績效的負向關係。
