征求林林业方面的翻译；英译汉

Impacts of exchange rates on international forest products trade are widely debated, but the
empirical evidence regarding this issue is still inconclusive. Here, we report findings of the
impacts of the exchange rates on the main forest product imports and exports of the US, from
January 1989 to November 2004. Export data consisted of monthly series of the main
products exported by the US to different countries. For imports we used monthly series of the
principal products imported by the US from Canada, the major source of imports. The
strongest evidence was obtained by pooling the data across countries and products. In the
short run, exports were very elastic with respect to the exchange rate (
2.6), while imports
were moderately elastic (1.2). In the long run, the elasticity decreased but remained significant
(0.5 for both exports and imports). Appreciation of the US dollar tended to matter more than
depreciation, but the hypothesis that the effect of exchange rate was symmetric could not be
rejected.

林业方面，不是很擅长，不好意思

什么东西？网页上翻译好了嘛，大概意思都差不多，自己再修改修改，估计差不多

原文在哪儿啊？

顶一下。

大家都在广泛讨论汇率对国际林业产品贸易的影响，但是关于这个问题的经验还不是很确定（没有形成系统理论）。这里将向大家介绍从1989年一月到2004年十一月，汇率对美国进出口的主要林业产品的影响。出口的数据是每月从美国出口至不同国家的主要产品的数据。而进口数据，我们用的是每月从加拿大进口的主要产品的数据，这也是进口的主要来源。最强有力的证据是来自于各国和各种产品的数据。短期而言，专家们对于汇率的态度还是很是很灵活的，而对于进口还算灵活吧。长期而言，这种弹性（灵活度）是下降的，但还是很重要的（对于进出口都是0.5）。美元的升值似乎比贬值更有影响力，但是也不能说汇率的影响是对称的这种猜想是不对的。

我是数学专业的，林业的专业术语不懂，希望大家不吝赐教，谢谢。

友情帮顶一下

我知道你是林业大学的
