人是否視為土地(land)？

經濟學上
土地、資本、勞力和企業家精神
這只是一種分類
因為觀念上，資本，勞力都是實質資源，也可是土地，但是全部都是土地資源，那麽分類太窄，不能反映甚麽結果
所以名詞的目的及定義只不過是一種分類方法，令人更具體明白及容易分類以作出決策。
如人類
成人、小童、男人，女人都是人類，但稱人類是無意思的，因為不能有效分類目的，所以應從為何要分類的目的開始。

In my opinion, if you are talking the factor of production in an economy, pure human beings who is doing nothing(only living in this planet) can't be counted as a factor of production because they are not producing anything. If human beings work, they will become labour as they are producing things to the economy. If human beings set up businesses, they will become entrepreneurs. All in all, I don't think human beings are Land. Umm....unless they are used as resource, like oil (burning human as fuel). But I don't think this would happen,hehe...

土地乃大自然給予的資源，人也是大自然給予的資源。兩者有着不同的用處，互相的合作。
