As supplier of most of the food we eat and of raw material for many industrial processes,agriculture is clearly an important area of the economy.But the industrial performance of agriculture is even more important than this.For in nations where the productivity of farmers is low,most of the working population is needed to raise food and few people are available for production of investment goods or for other activities required for economic growth.Indeed,one of the factors related most closely to the per capita income( 人均收入) of a nation is the fraction (一部分)of its population engaged in farming.In the poorest nations of the world,more than half of the population lives on farms.This compares sharply with less than 10% in Western Europe and less than 4% in the United States.
In short,the course of economic development in general depends in a fundamental way on the performance of farmers.This performance,in turn,depends on how agri¬culture is organized and on the economic environment,or market structure,within which it functions.In the following pages the performance of American agriculture is examined.It is appropriate to begin with a consideration of its market structure.

众所周知,农业是一个非常重要的经济领域.它为我们提供了绝大部分的粮食,并且还为很多工业生产提供了原材料.但是相比而言,农业的工业特性更为重要.因为在一些农业生产力低下的国家,需要很大一部分劳动力来提升粮食产量,但是生产投资货物及进行其他经济增长所需活动的可用劳动力又很少.实际上,衡量一个国家的人均收入很大一部分要看其从事农业生产的人数.世界上最穷的国家有一半以上的人口依靠农业生存.与之形成鲜明对比的是,西欧只有10%的人口,美国只有4%人口依赖农业生存.简单地说,一般来讲经济发展的过程依赖于农民作为经济基础的功用.反过来,这种功用又依赖于农业的组织形式以及这种功用所作用于的经济环境,或者说市场结构.下一页里我们将对美国农业的功用做一个了解.在此之前有必要先了解一下美国的市场结构.
