《管子·八观》
那种土地均已开垦，而人民仍无积蓄的国家，是因为国土小而耕地少；土地只开垦半数，而民有余食、粟米丰富的国家，是因为国土大而耕地多。
彼野悉辟而民无积者，国地小而食地浅也。田半垦而民有余食而粟米多者，国地大而食地博也。
A country whose land has been fully cultivated but its people still have no savings is small in size and has little arable land; a country whose land is only half cultivated but its people have abundant grain and surplus corn is large in size and has much arable land.
