交换的出现和发展,是生产力发展的结果与社会进步的标志。商品经济不可逾越的深层原因在于交换在社会生产中的特殊地位。人类社会在生产领域与流通领域两个不同的领域和不同层次生产作用下,沿着两条平行的发展线路前进。商品经济之发展非但不会与社会主义公有制经济撞车,而且两者的交互积极影响将有力推动社会前进。 The emergence and development of exchanges are the result of the development of productive forces and the symbol of social progress. The underlying reason why the commodity economy is insurmountable lies in the special position of exchange in social production. Under the two different fields of production and circulation and the production of different levels of production, human society follows two parallel development routes. The development of the commodity economy will not only crash with the socialist public ownership economy, but also the positive interaction between the two will strongly push forward the social progress.
