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
When land of the third quality is taken into cultivation, rent immediately commences on the second, and it is regulated as before, by the difference in their productive powers. At the same time, the rent of the first quality will rise, for that must always be above the rent of the second, by the difference between the produce which they yield with a given quantity of capital and labour. With every step in the progress of population, which shall oblige a country to have recourse to land of a worse quality, to enable it to raise its supply of food, rent, on all the more fertile land, will rise.

白话
当第三等土地被耕种时,第二等土地立即产生地租,地租由两者生产力差异决定。同时,第一等土地的地租也会上升,因为它总比第二等高出两者在等量资本劳动下的产量差。人口每增长一步,迫使国家耕种更差土地以增加粮食,所有较肥沃土地的地租都会上涨。核心是地租随人口压力和耕种边际下移而上升。做法是:分析地租时,盯住边际土地质量和产量差。
上下文
李嘉图阐述级差地租理论,说明人口增长如何推动地租上涨。
今日一问
你所在行业是否也存在“边际质量下降推高优质资源租金”的现象?
