This paper investigates the effect of privatization on welfare or the optimal export taxes policy in differentiated mixed oligopoly. The main findings of our paper is as follows:(1) If the two firms take the same competition, i.e., Cournot or Bertrand competition, and the degree of privatization has no effect on welfare or the optimal export taxes. (2) We analyze the strategic variables are determined endogenously. If degree of privatization , two private firms will take Cournot competition strategy；If degree of privatization , two firms will take q-q competition strategy or p-p competition strategy or q-p competition strategy or p-q competition strategy. In this case, social welfare is higher if the state-own firm and private firm choose quantity contract. Finally, when the equilibrium under Cournot competition in a mixed duopoly with partial privatization, Government how adjust export tax to maximize social welfare.參考文獻 邱俊榮與黃鴻(2006)，〈公營廠商民營化的最適釋股比例分析〉，《經濟論文叢刊》，34(2)，246-259。林瑞益與孫嘉宏(2017)，〈整合型市場之下的混合雙占-價格與數量競爭〉，《經濟研究》，53(2)，261-294。翁永和，羅鈺珊與劉碧珍(2006)，〈市場結構與最適民營化政策〉，《經濟論文》，31(2)，149-169。Bárcena-Ruiz, J.C. and M.B.
