主张人民币应该升值的人大多认为,这些年中国贸易条件持续恶化,如果人民币升值,则可以改善贸易条件。为此,我们首先要问:贸易条件改善一定地会增加一国的福利吗?其次,汇率升值会改善一国的贸易条件吗?汇率升值是通过怎样的机制改善一国的贸易条件的?反之,汇率贬值会恶化一国的贸易条件吗?汇率贬值是通过怎样的机制恶化一国的贸易条件的?

Secondly, will the appreciation of the exchange rate improve the terms of trade of a country? By what kind of mechanism will the appreciation of the exchange rate improve the terms of trade of a country? , Devaluation of the exchange rate will deteriorate the terms of trade of a country? Exchange rate depreciation is through what mechanism to deteriorate a country’s terms of trade?
