    本文首先介紹了中美、中歐紡織品貿易爭端的來龍去脈，由此可知在涉外貿易這種以高投入、高風險著稱的行業里，如何甄別和規避外貿風險、如何選擇合適的投資項目已經成為外貿企業的首要問題。因此，正文分別從統計學、博弈論和投資組合三種角度對涉外紡織品貿易公司風險進行了定性和定量的分析，這也是本文的主要研究內容。首先，統計學篇選取了深圳證券交易所行業分類指數?紡織服裝指數（ ti ）每一季度末的交易收盤價和若干種反映宏觀經濟變化的指標，利用計量經濟學中時間序列的協整檢驗、 granger因果檢驗和脈沖反應函數等理論做實證分析，從而得知反映國內物價水平和國內外經濟景氣程度的經濟指標對紡織板塊上市值的沖擊比較明顯，且可知沖擊程度和時滯度，進而分析出涉外紡織企業所面臨的宏觀經濟風險;接著，從博弈論的角度具體分析一家紡織品出口公司（ beauty ）的外貿活動所面臨的各種經營風險，該篇從博弈擴展圖入手，分析了出口目的國審查方式與本企業出口策略之間的制度安排;並圍繞雙方的利益分配，研究了有限回合和無限回合合作談判博弈，然後具體論述了國家責任和企業涉外經營風險等問題;在一定程度上為了實現投資多元化來分散風險的目的，投資組合篇從經典的markowitz模型著手，在一些特定條件的限制下，給出了一個相應的投資組合模型。
