在競爭激烈的經濟環境下,「企業全球化」已是企業追求競爭優勢之重要策略,藉由專業分工以達成全球資源最適配置之目的,進而使利潤極大化。在全球化的過程中,一個從事國際貿易與經濟的跨國企業有了國外所得時,必然面臨國際租稅之課題。租稅是企業主要成本之一,是以,本文研究以跨國企業重複課稅與國際租稅策略規劃為研究主軸,並探討跨國企業移轉計價議題。本研究藉由彙整國內、外有關國際租稅策略規劃相關文獻、法令及研究報告,探討租稅相關主題。此外,本研究以一家上市跨國企業作為個案公司,以深度訪談及資料收集方式,探討個案公司租稅問題。透過個案公司的瞭解可知,中國租稅變革中盈餘匯出需課稅,會影響個案公司在中國盈餘匯出境外之意願。而個案公司海外控股公司股權移轉所引起租稅問題,可作為未來跨國企業進行海外控股公司股權移轉之參考。 Under the intensive competition, the globalization has already been one of the most important strategies for the enterprises pursue the competitive advantage.
