Historical records show that in the devel-oped countries the growth rate of category I was faster at the outset,but that it hasgradually slowed in the past few decades.Thanks to the growing knowledge-intensiveindustry and other factors,the rate of growth of category II(the means of consump-tion) will exceed that of category I.While analyzing the relationship between thetwo major categories, the author expounds the changes in the ratio between objectsof labor and the means of labor. He points out that the general law governing changesin the industrial structure and reproduction ratio resulting from technological pro- gress will be of help for guiding China’s economic construction.展开更多
