民國七十年代開始台灣在新台幣急遽升值、工資上揚、地價飛漲和環保抗爭等不利因素的衝擊下,促使高勞力密集的產業,紛紛移往海外分散投資,以尋求有利企業生存的空間。隨著國際間資金流動頻繁、企業國際化趨勢,我國製造產業為提升國際競爭力,自民國八十年代以後對外投資成為業者之重要經濟策略。 過去針對多國籍企業匯率風險的研究,著重於探討匯率變動和股票報酬率或經營成果的關聯性,且國內尚無人對製造業「累積外幣換算調整數」科目和公司價值的關聯性做深入的研究。因此,本研究分別以會計學角度以及經濟學角度探討「累積外幣換算調整數」與公司價值的關聯性,並採用關聯性研究法針對民國83年至民國92年的多國籍製造業進行研究,分別由「年度分析」及「Pooled Analysis」二方面進行實證分析。 研究結果顯示,大部分年度分析並不支持本研究之假說;而不分年度樣本部分,分別在10%及5%的顯著水準下,支持累積外幣換算調整數的變動和公司價值變動間具有關聯性,而且呈負相關。且亦發現外幣兌換損益和股票報酬率呈正相關之變動。
This study presents an economic analysis of the foreign translation adjustment and empirically examines the association between change in firm value and the foreign translation adjustment for a sample of manufacturing firms. The study shows that, for firms in the manufacturing sector, most yearly analyses do not support the assumption. However, pooled analysis proves that the translation adjustment is associated with a loss of value instead of an increase in value. The result stems from the fact that, for firms in the manufacturing sector, the accounting rules governing foreign currency translation generally produce results opposite to the economic effects of exchange rate changes. Furthermore, the result also investigates the transaction gain or loss is positive associated with stock return.
