在現在的社會裡，「旅遊」已經是人們不可或缺的一部份，若到外國旅遊，我們會先購買旅遊目的地的貨幣，當一趟旅遊結束時，會再將剩餘的貨幣賣掉，買賣的對象皆為銀行。也就是說銀行扮演一個中介的角色，能夠從中賺取匯差。但假設有一個平台，能夠直接在上面找到一位需要該貨幣的人，買賣雙方能根據某種機制得到合適的匯率，並依該匯率直接進行交換，這樣不但能以更好的匯率買到貨幣，也能省下原本應該付給銀行的手續費。然而，當去中介化後，該怎麼建立交易雙方之間的「信任」，就變成了一個很重要的問題。 而區塊鏈是一種不依賴第三方、通過自身分散式節點進行網路數據的存儲、驗證、傳遞和交流的一種技術。其具有去中心化、透明性、開放性、獨立性、安全性及匿名性…等性質。 / In current society, "travelling" is already an integral part of their life. For travelling abroad, we will purchase the currency of the tourist destination first and then sell the remaining currency after the tour: The objects of trading are all banks. That means the bank plays an intermediary role and can earn the exchange difference from this trading. However, if it is supposed that there is a platform which people could directly find a person who needs the currency, both of the buyer and seller can get an applicable exchange rate according to some reasonable mechanism, and then they can directly exchange at that exchange rate. In this case, not only the currency can be bought at a better exchange rate, but also they could save the original fee which they pay to the bank. However, it becomes a very important issue to establish the "trust" relationship during the trade. The blockchain is a kind of technologies that relies on independent nodes to store, verify, delivery and exchange network data without relying on a third party. There are the properties of decentralization, transparency, openness, independence, security, anonymity….and so on. We can use the nature of the blockchain to strengthen the trust between buyers and sellers, in order to increase the security of this platform. This study will explore the feasibility of this platform.

由於台灣資源並不豐富，市場有限，對外進出口（含製造）自然成為維繫台灣經濟的命脈。因此國內總體經濟環境容易受到國際經濟變數的影響，而匯率波動就是對國際貿易一個直接衝擊的因素。企業的匯率風險來源主要有二，一為交易性風險（Transaction Exposure），一為換算性風險（Translation Exposure）。本研究將針對台灣境內多國籍公司的匯率風險進行研究，探討會計衡量與公司價值的關聯性，亦即外幣匯兌損益與外幣換算調整數與公司價值之關係。 本研究採「關聯性研究法」針對民國79年至民國86年的多國籍公司進行研究，並分由「年度分析」與「Pooled Analysis」二方面進行實證分析。此外，本研究又考量了股票報酬與外幣匯兌損益及外幣換算調整數間可能具非線性關係，故又採Regressions on Ranks的方式探討此非線性關係是否成立。 本研究大部分年度分析並不支持本研究之假說。本研究之部分模式的實證結果支持市場在評價公司時，會將損益表的外幣匯兌損益及股東權益項下的外幣換算調整數納入考量。且亦發現市場對於二者所持態度是無差異的，亦即市場對於二者的考量權重並不具顯著差異。 / This study examines whether the stock market considers foreign exchange transaction when pricing securities about multinational firms. It primary examines the relations between the foreign exchange gains and losses in the income statement, the foreign translation adjustments in the stock equity, and stock price. Most of the results from the annual analysis do not support the hypotheses of this study. But some of the results from the pooled analysis support the hypotheses of this study. It suggests that the stock market will consider both the foreign exchange gains and losses in the income statement and the foreign translation adjustments in the stock equity when pricing securities. And it also suggest that the weights the stock market gave them show no significant difference.
