本研究以臺灣地區國際貿易類外資企業為研究對象，以談判力為觀點，探討外資 企業進入臺灣市場一段時間後，與臺灣合作伙伴間，國際行銷通路垂直關係的變動狀況。 本研究以 Cox 間斷式危險率模型為分析工具，將談判力分為七大構面， 其中以市場特性因 素、地主國因素、市場推進策略、廠商類型等四大類因素具顯著性。除市場特性因素與通路 垂直關係的變動為負向關係外，其餘皆為正向的關係。 本研究管理上的涵義計有： 1.就市場前景的評估，本國企業宜採全球性的整體考量，避免過度樂觀的本位主義。 2.與外資企業維持良好與持續性的互動關係，消極減低通路關係的變動率。 3.注意產業生態的變動警訊，以降低外資企業一窩風效果的衝擊。 4.國內企業宜對政府相關措施的適時性與適合性加以監控，確保產業的合理競爭地位。 5.代理商需隨時注意外資的動態，尤其是通路導向型產業尤須積極注意合作伙伴的整合動態 。
