关鍵在于拖拉机和汽車十几、二十年內,最偉大的变化,也許是亿万农民全都用上机器。在用人力和畜力耕作、运輸的情况下,平均每一个劳动力大約只能供养三、四人,而且他們的消費水平还是較低的。如果用机器,再加上化学肥料;那么,平均一个劳动力大約可以供养二、三十人,并且消费的水平还較高。像我們这样的国家,采用成百万輛拖拉机和汽車,就可以替出成亿的劳动力;来兴办工业,和发展科学文化事业。到那时,貧穷落后就永远消逝,历史将翻开新的一章。如果說,科学技术現代化是工农业現代化的关键,同时,工业現代化又是农业現代化的钥匙;那么, The key lies in the greatest change in tractors and automobiles in a decade or two. Perhaps the hundreds of millions of farmers all use machines. In the case of farming and transportation using human and animal power, the average worker can only support three or four people, and their consumption level is still relatively low. If machines are used together with chemical fertilizers, then an average worker can provide about twenty or thirty people, and the level of consumption is still high. In countries like ours, millions of tractors and cars can be used to replace hundreds of millions of workers; to build industries, and to develop science and culture. At that time, poverty and backwardness will disappear forever, and history will open a new chapter. If we say that the modernization of science and technology is the key to the modernization of industry and agriculture, at the same time, industrial modernization is also the key to agricultural modernization; then,
