生活在现代社会中,我们几乎每时每刻都要同商品打交道。作为消费者,我们消费的是商品;作为生产者,我们生产的是商品;而且我们是在用商品生产商品,因为在现代商品经济条件下,生产过程中使用的各种要素,绝大多数都是作为商品购买来的。那么,什么是商品呢?显然,商品首先应当是对人有用的物品,如果对人没有用处,它就不可能拿到市场上去出售。但是,为什么空气、阳光是人类生存之必需,却没有价格,不能在市场上作为商品出售呢?显然,“对人有用”可以是物品成为商品的一个必要理由,但并不是充分的理由。你或许会进一步补充说,物品要成为商品,还必须是人类劳 Living in modern society, we deal with goods almost at all times. As consumers, we consume goods; as producers, we produce goods; and we are producing goods from goods, because in the modern commodity economy, the vast majority of the various elements used in the production process It is purchased as a commodity. So, what is a commodity? Obviously, the commodity should first of all be a useful item to people and can not be marketed if it is of no use to people. However, why air and sunlight are necessary for the survival of mankind without any price and can not be marketed as commodities? Apparently “useful for human beings” can be an essential reason why an article becomes a commodity, but it is not a sufficient reason . You may further add that items must be human labor if they are to become commodities
