本研究主要以赴陸投資的台商企業作為研究標的，探討2005年至2016年間資本結構變化，對於資產報酬率的影響，同時導入2005年至2016年人民幣匯率機制改革前、後匯率風險干擾因子對資產報酬率，針對不同波動性程度實證分析兩者變化之關聯性影響。實證結果發現在控制其他可能影響資本結構決定的因素後，資本結構變化及人民幣匯率變動對資產報酬率具有顯著相關性，顯示台灣廠商投資兩岸三地，利用美元、人民幣、新台幣間借、存款互為應用之財務槓桿操作不僅能達成避險的目的，同時亦可賺取可觀的 easy money。 本文擬以人民幣匯率機制改革作為樣本，預期人民幣匯率機制改革前、後，財務槓桿操作對台商企業資產報酬率所產生不同的影響，推論人民幣匯率機制改革後波動幅度加大，將造成廠商交易意願改變、匯率風險加劇及避險成本提高，進而改變公司管理當局與投資人預期報酬降低等現象，藉由本研究分析結果將可提供公司及投資人未來在考量匯率及利率波動度風險時，應如何進行全面性的避險操作策略。 This essay focuses on the investment of Taiwanese enterprises as the subject of research, to explore the capital structure change from 2005 to 2016, the impact on the return on assets , and import the 2005-2016 RMB exchange rate mechanism before and after the reform.
