是微观经济学分析和研究资源最优配置的基本方法,它首先是一种正确的决策思想,边际即“额外”,“追加”之间。用边际分析法来衡量一个方案或一项活动是否有利,就是要把这个方案或活动引起的额外成本(边际成本)与引起的额外收益(边际收入)相比,如果后者大于前者,就是有利的,否则就是不利的,这种决策方法体现了向前看的决策思想。

Last week we went mountain-climbing. Even the heavy rain in the morning couldn’t prevent us go. Setting off very early, we went along an extreme narrow road. On every side of the road were green fields and some farm house. We could hear the sound of the rain and our footsteps mixing with our laughter. At noon we reached the top of the mountain. That surprised us most was the beautiful scenery. After having short rest there and sharing with the food we had brought, we started going down. It had rained even harder. We were all wet, and we still sang and laughed happily. _____________________________________________________________________________ |
