术语“马歇尔-勒纳条件”的详细信息

英译术语:

Marshall-Lerner Condition

汉语语境:

马歇尔—勒纳条件是分析汇率变动对贸易收支影响的重要理论。通过分析我国对不同经济体的茶叶进出口需求弹性，并构建实际有效汇率等因素与茶叶贸易收支的计量模型，可发现我国茶叶进出口与马歇尔—勒纳条件间的满足关系。我国与不同国家的茶叶贸易收支受汇率变动的影响不同；就我国茶叶对外贸易总体而言，茶叶进口价格下降会增加进口额，出口价格上升会增加出口额；而人民币升值会改善我国茶叶贸易收支，人民币贬值会恶化我国茶叶贸易收支，且进出口需求弹性之和小于1.因此，我国茶叶贸易收支反向符合马歇尔—勒纳条件。

英语语境:

The Marshall-Lerner Condition is one of the most important theories analysing the impact of exchange rates on BOPs. To figure out whether China's tea trade meets the Marshall-Lerner Condition or not, we build a econometrics model showing the relationship between real exchange rate of RMB and China's tea BOPs by analyzing the elasticity of China's tea import-and-export towards different economies. The result explains that the effect of tea trade on RMB exchange rates varies with trading countries. Generally, the fall of tea import price will give rise to the import value, while the increase of export price will make import value go up. The appreciation of RMB will promote China's tea BOPs, while the devaluation of RMB will worsen BOPs. Moreover, the demand elasticity of imports and exports is less than 1 altogether. Therefore, China's tea trade is consistent with the Marshall-Lerner Condition.
