19世纪时,资本和劳力在经济增长中占首位,到了20世纪50年代以后,科技的作用占了首位。邓小平提出的“科学技术是第一生产力”,正是发展了马克思主义生产力理论。同时,以往第一、第二产业占绝大比重,到本世纪50年代以后,第三产业占的比重最大。科技生产力与第三产业成为衡量社会经济发展水平的标尺。 In the 19th century, capital and labor dominated economic growth. By the 1950s, the role of science and technology took the first place. Deng Xiaoping's “Science and Technology Are the Primary Productive Forces,” It is precisely the development of Marxist theory of productive forces. At the same time, in the past, the primary and secondary industries accounted for the largest proportion. By the 1950s, the tertiary industry accounted for the largest proportion. Science and technology productivity and the tertiary industry have become the measure of the level of social and economic development.
