The Marshall-Lerner Condition is one of the important theories to explore the impact of exchange rates on BOPs. This paper uses the annual data of China’s tea import and export from 1986 to 2008 to analyze whether China’s tea trade meets the Marshall-Lerner Condition or not. In order to achieve this purpose, we calculate the demand elasticity of China’s tea import and export, and build the econometrics model to analyze the relationship between the real exchange rate of RMB and China’s tea BOPs. The result explains that the tea trade between China and other countries shows different effects to the changes of RMB exchange rates. On the whole, the rise of tea export price will give rise to the tea export value, while the decrease of tea import price will increase the import value. The appreciation of RMB will promote China’s tea BOPs, while the devaluation of RMB will worsen BOPs, The demand elasticity of imports and exports is less than 1, so basically speaking, China’s tea trade is consistent with the Marshall-Lerner Condition.
