producer surplus

A rise in market prices increases producer surplus by allowing sellers to earn more than their minimum acceptable price.市场价格的上涨允许卖家获得高于其最低可接受价格的收益，从而增加了生产者剩余。

Trade liberalisation can transfer producer surplus from domestic firms to foreign competitors.贸易自由化可能会将生产者剩余从国内企业转移到外国竞争对手手中。
