关于机会成本,经济学家是这样告诉我们的:资源是有限的,资源的有限性决定我们在做什么上必须作出选择,而选择就意味着机会成本——多年产一个单位的某种产品就必须以少生产若干单位的另一种产品为代价。只有一个亿,或搞开发、或搞环保;只有一千万,或修大楼、或修公路;只有一百万,或建学校、或建另墅;只有十万,或买几台电脑、或买一夜豪赌。两全其美固然好,但“此事古难全”。
On the opportunity cost, economists tell us: resources are limited, the limited resources determine what we have to make a choice, and the choice means that the opportunity cost - a unit of a multi-year production of a product It must be at the expense of producing fewer products of several units. Only one hundred million, or engage in development or environmental protection; only 10 million, or repair the building, or repair the road; only one million, or build a school, or build another villa; only 100,000, or buy a few computers, or Buy one night gamble. The best of both worlds is good, but “the whole story is hard to find.”
