本文基于对上世纪90年代至2005年的四个亚洲国家与美国间双边出口贸易数据的实证结果比较,采用VAR方法证明了存在一个成熟有效的远期外汇市场可以帮助出口企业规避汇率风险。最后,引用泰国案例,实证说明为了确保远期外汇市场能够提供准确的汇率价格信号,政府不应过度干预该市场。 Based on the comparison of the empirical results of the bilateral export trade data between the four Asian countries and the United States from the 1990s to 2005, the VAR method is used to prove that the existence of a mature and effective forward foreign exchange market can help the exporters to evade the exchange rate risk. Finally, the case of Thailand is cited and empirical evidence shows that in order to ensure that the forward foreign exchange market can provide accurate exchange rate signals, the government should not unduly interfere with the market.
