Abstract: From the point of investment, with higher capital-labor ratio and higher labor productivity thanthe low-end sectors, the high-end sectors have more outputs and profits. So, in market economy, investmentwill naturally concentrate on the high-end sectors, and this will result in the imbalanced growth of industrialstructures and income structures. From the point of consumption, higher income will increase higher-level de-mand, with the bandwagon effect to other income class. In a word, with different income level and populationscale, different consumption structures will affect the growth of the high-end sectors.

Key words: imbalanced productivity structures, high-end sectors, low-end sectors

摘要： 从投资角度看,高端部门的资本有机构成和劳动生产率比低端部门要高很多,在一定的投资下,高端部门会有更大的产出或利润。因此,在市场经济条件下投资自然会向高端部门倾斜和集中,其结果将形成产品或产业结构的不平衡增长,从而引起人们收入结构的不平衡增长。从消费角度看,人们在收入增长以后,会努力满足较高层次的需求。如果存在不同收入结构,这种倾斜最先出现在高收入阶层,这一现象又会渐次对其他各收入阶层产生“示范效应”。简言之,不同收入阶层人口的消费结构会先后出现对高端部门产品的倾斜,当然,消费的这种倾斜将受到低收入阶层的收入水平、人口规模的影响,最终将影响高端部门的增长。
