有效资源流动、比较优势与收入差距——以自然收入差距为收敛值

The Effective Resources Flowing,Comparative Advantages and Income Gap for the Convergence of Natural Income Gap

关于收入差距研究的著述很多,但都没有从自然收入差距的视角来深入研究。以自然收入差距为收入差距缩小的收敛极限值,建立相关分析模型,对形成收入差距的变量进行分析,进而揭示出有效资源流动、比较优势与收入差距的关系:如果有效资源得不到及时流动或不流动,则经济体不能把有效资源转化为比较优势;而在比较优势得不到充分发挥的条件下,各经济体不能形成具有竞争力的均衡态势,从而降低经济效率并使收入差距越来越远离自然收入差距。因此,收入差距的拉大是因为有效资源得不到充分流动,缩小收入差距的关键在于建立健全促进有效资源的流动的各种"软性"和"硬性"措施;在有效资源不断充分流动下,收入差距将收敛于自然收入差距。

There are a lot of researches on income gap, but these researches do not make deep studies from the angle of natural income gap. Natural income gap is used as the utmost limit value of gap-narrowed convergence to set up the related analysis model and to analyze the variables to form income gap in order to reveal the relationship among effective resources flowing, comparative advantage and income gap. If the effective resources are not flowing in time or do not flow, the economic body can not transform the effective resources into comparative advantage, under the condition of that comparative advantage is not sufficiently brought into fully play, however, each economic body can not form equilibrium state which has competence so that economic efficiency is decreased and income gap is more and more away from natural income gap. Thus, the enlargement of the income gap results from insufficient flowing of the effective resources, the key to narrowing the gap lies in making and perfecting all kinds of soft and hard measures to promote the flowing of the effective resources, and the income gap will converge to natural income gap under the condition of continuous and sufficient flowing of the effective resources.
