我國過去以出口為導向的經貿政策，帶動了持續穩定的經濟成長並累積鉅額的外匯存底。近年來隨著經濟發展的日益蓬勃，國內的投資環境面臨了前所未有的衝擊；廠商為求企業之經營成長及競爭優勢，無不致力於降低生產成本，擴大市場規模，因此形成一股前往海外投資的熱潮。本文主要目的是利用「或有請求權法-購入選擇權(CallOption)」訂價理論分析國內出口廠商面對各項投資環境之不確定性因素衝擊時，如何決定「對外投資之最適時機」。因此，本文模型具有下列幾特點：（一）以個別廠商之觀點，探討對外投資之最適時機。（二）探討投資國及地主國生產成本相對變動時，對外投資最適時機之影響。（三）探討投資國及地主國外匯匯率變動時，對外投資最適時機之影響。（四）探討投資地主國享有對外優惠關稅待遇時，對本國廠商對外投資最適時機之影響。（五）探討廠商之研究發展成果與對外投資最適時機之影響。

兩岸經貿在政治的隔閡與反復中，從小到大，從封閉到逐漸開放。在這個過程中，兩岸資金融通的不斷擴大成為這場華麗經濟表演的背景。但隨著人民幣在國際舞台角色變化，兩岸貨幣流通從背景中走出，金融合作發展甚至可能成為兩岸經濟未來的最重要之組成。 從法律角度審視兩岸跨境資金流通，繁瑣的管制措施與複雜的法律體系正在逐漸消減。從直接投資角度而言，對外中國大陸不斷推動外商投資企業法規的改制以吸引外商投資；對內則努力減少中國企業融資阻礙，以推動中國大陸企業走出去。而台灣雖然對於陸資仍然保持著較大的戒心，亦逐步放開對大陸投資管制，並開放陸資來台來台促進經濟發展。從間接投資角度而言，中國大陸逐步放開資本項下的管制， QDII、QFII等投資管道不斷推陳出新，更加開放的未來成為可能。 而在這場以人民幣國際化為目的的改革中，自貿區扮演了急先鋒的角色。自貿區階段式的政策開放有著中國大陸改革和法律變遷的典型特征，「試點—推廣」模式使自貿區走在了人民幣國際化的最前沿。而台灣的自由經濟示範區卻步入了困境。 自貿區的現在很大可能將會是中國大陸的未來，人民幣國際化成為一個大概率事件。面對這種未來，台灣可以如何應對？從法律角度而言，本文提出以下四個建議：1．推動兩岸貿易以本幣結算，深化兩岸經貿往來；2．建立雙邊貨幣交換機制，共同推動人民幣區域化及國際化；3．推動兩岸資本市場的交流與合作，建構台灣為人民幣離岸中心；4．推動兩岸金融監理合作、建置兩岸金融防火牆。 / The economic and trade have developed since 1980s though faced with the political barriers. The two sides is expected to work together in peace in the future. From the perspective of cross-border capital flow, the two sides set up a complicated and complex control measures, forming a complex legal system. From the view of direct investment, China is currently promoting the restructuring of foreign investment enterprises and regulations to attract foreign investment. Reducing the financing pressure of Chinese enterprises and promoting the Chinese mainland enterprises to go out become one of the focus of the mainland policy. However, Taiwan resist the Chinese capital. From the perspective of indirect investment, China's mainland is currently expanding various investment pipelines, such as QDII, QFII, etc.. In the future, capital of cross-border capital flows will be more convenient. Taiwan also has more space to intervene. The establishment of free trade zone has become the pioneer of China's financial reform, and its development has been the most advanced in the financial reform, capital projects and the internationalization of RMB. Negative list and a series of financial reform measures will gradually move to the country. Taiwan's free economic demonstration zone has entered a difficult situation. Facing such a future, from a legal point of view, this paper puts forward the following five suggestions: 1. Promote cross-strait trade in local currency settlement, deepen economic and trade exchanges between the two sides; 2. The establishment of bilateral currency exchange mechanism, and jointly promote the RMB regionalization and internationalization; 3. To promote exchanges and cooperation on both sides of the capital market, build Taiwan as an offshore RMB Centre; 4. To promote cross-strait financial supervisory cooperation, build cross-strait financial firewall.

台灣對國際貿易市場依賴程度極高，總體經濟環境極易受到國際經濟變數的影響，其中尤以匯率的變動，係我國進出口貿易最直接並重要的影響因素之一。為了生產及銷售競爭之需要，我國企業積極對海外投資並設立海外子公司或據點以進行國際分工，企業的國際化更加重所面臨匯率波動所產生的外匯暴露。 本研究基於我國企業面對的外匯暴露程度，探討影響我國企業外匯暴露及操作衍生性金融商品規避外匯暴露的公司治理因素，並針對外匯避險是否具有盈餘資訊內涵進行研討，具體而言，本研究將探討下列問題： 一、操作衍生性金融商品規避外匯暴露與外匯暴露程度的關聯性； 二、公司治理對操作衍生性金融商品規避外匯暴露的影響程度； 三、操作衍生性金融商品規避外匯暴露是否具有資訊內涵。 本研究的結果發現，操作衍生性金融商品係有助於規避外匯風險；而公司治理中的董事能力及董事會的獨立性則對我國企業在是否選擇操作衍生性金融商品避險時，有重大影響力。基於外匯暴露是我國企業普遍面臨的風險，上述結果應有助於我國企業在面對外匯風險時，決定是否採用衍生性金融商品規避外匯風險上，有一定的助益。本研究並發現企業操作衍生性金融商品避險是具有盈餘資訊內涵的，此對文獻中較少針對企業面對風險的避險決策是否對股票報酬有所影響的議題，可作為該領域研究方向及結果的補強。 / Due to an extremely high level of dependence on international trade, the macroeconomic environment in Taiwan is affected by international economic variables deeply. Particularly, the change of foreign exchange rates is one of the most direct and significant factors for the international trade of Taiwan. Further, the internationalization of local enterprises by actively expanding their investment internationally and setting up overseas subsidiaries makes these enterprises suffer more from the exposure of foreign exchange rate fluctuations. This study therefore investigates the following issues: 1. The association between hedging foreign exchange rate fluctuation by derivatives and the foreign exchange rate exposure. 2. The impact of corporate governance on the hedging decisions of the management. 3. Is there any information content of the hedging against foreign exchange rate exposure? The results of this study show that: (1) The hedging against foreign exchange rate fluctuation by derivatives decreases the foreign exchange rate exposure; (2) Two of corporate governance factors namely finance expertise and independence of the board of directors have significant effects on the hedging decisions; and (3) Hedging against the foreign exchange rate fluctuation by derivatives provides information content of earnings. This study contributes to the practice and the academics in the following ways: (1) As an aid for the management to decide whether to hedge against foreign exchange rate fluctuation by derivatives when facing foreign exchange rate exposure; (2) As an extension of the literature on the association between hedging decisions and the stock returns.
