If from a consideration of these circumstances, the profits of stock should be so adjusted that in one trade they were 20, in another 25, and in another 30 per cent., they would probably continue permanently with that relative difference, and with that difference only; for if any cause should elevate the profits of one of these trades 10 per cent. either these profits would be temporary, and would soon again fall back to their usual station, or the profits of the others would be elevated in the same proportion.

白话
如果由于上述考虑,各行业利润率形成相对差异,比如20%、25%、30%,这种差异会长期保持。若某行业利润突然高出10%,要么是暂时的,很快回落;要么其他行业利润也相应提高,恢复原有相对差距。所以,长期来看,利润率差异是稳定的,反映各行业的特点。
上下文
李嘉图论述利润率差异的长期稳定性,以及资本流动对差异的调节。
今日一问
你能否识别不同领域回报率差异背后的长期因素,而不被短期高利润迷惑?
