在国民经济的运行过程中,物资产品投入流通过程的数量以及交通运输所能承担的运力大小,便构成交通运输的主要矛盾。马克思交通运输理论是马克思经济理论的重要组成部分。交通运输业的发展是经济社会发展的先行和先决条件。 During the operation of the national economy, the quantity of materials and products put into circulation and the amount of capacity that transport can afford have constituted the major contradiction in transport. Marx’s theory of transportation is an important part of Marx’s economic theory. The development of transportation industry is the first and foremost condition of economic and social development.
