“超额利润”的英语表达是 "excess profit" 或 "super-normal profit"。
Excess profit:强调利润超出正常或预期水平,是较为常用的表达。
Super-normal profit:更侧重于利润超过正常回报率的部分,常见于经济学讨论中。
根据语境选择即可,例如:
The company earned significant excess profit last year.(该公司去年获得了可观的超额利润。)
In a competitive market, super-normal profits tend to attract new entrants.(在竞争市场中,超额利润往往会吸引新进入者。)
