大卫·李嘉图《政治经济学及赋税原理》· On the Principles of Political Economy and Taxation · 投资

The rise of rent is always the effect of the increasing wealth of the country, and of the difficulty of providing food for its augmented population. It is a symptom, but it is never a cause of wealth; for wealth often increases most rapidly while rent is either stationary, or even falling. Rent increases most rapidly, as the disposable land decreases in its productive powers. Wealth increases most rapidly in those countries where the disposable land is most fertile, where importation is least restricted, and where through agricultural improvements, productions can be multiplied without any increase in the proportional quantity of labour, and where consequently the progress of rent is slow.

白话

地租上涨总是国家财富增加、人口增多后粮食供给变难的结果。它是财富的症状,从来不是财富的原因;财富增长最快的时期,地租常常停滞甚至下降。地租涨得最快的地方,往往是可耕地的生产力在下降;财富涨得最快的地方,则是可耕地最肥沃、进口限制最少、农业改良能使产量增加而不必同比例增加劳动,因此地租上涨很慢。所以别把地租上涨当成繁荣的功劳,它更多是资源约束的信号。

上下文

李嘉图总结地租与国民财富的关系,强调地租是结果而非原因,并联系自由贸易与农业改良。

今日一问

你身边哪些“涨价信号”其实是资源约束的警报,却被误读成了繁荣的证据?
