For a favourable balance, provided it is not too large, will prove extremely stimulating; whilst an unfavourable balance may soon produce a state of persistent depression.

对于一个有利的平衡，只要它不是太大，就会被证明是非常刺激的；而不利的平衡可能很快会产生持续的抑郁状态。

It is, indeed, arguable that in the special circumstances of mid-nineteenth-century Great Britain an almost complete freedom of trade was the policy most conducive to the development of a favourable balance.

事实上，在 19 世纪中叶英国的特殊情况下，几乎完全的贸易自由是最有利于形成顺差的政策，这一点确实值得商榷。

The earlier mercantilists laid great emphasis on this and were often to be found opposing trade restrictions because on a long view they were liable to operate adversely to a favourable balance.

早期的重商主义者非常重视这一点，并且经常被发现反对贸易限制，因为从长远来看，他们很容易对有利的平衡不利地运作。
