本文在社会生产的视角下,通过分析生产要素所有者的收入对收入差距问题进行研究。研究发现一国收入分配差距拉大的主要原因是各生产要素与其对社会生产的贡献率之比不相等,从而导致各生产要素所有者之间的收入存在差别。如果一国希望缩小收入差距必须根据该国各生产要素对社会生产的贡献调整生产过程中的生产要素投入量或者根据该国各生产要素的投入量调整各生产要素对社会生产的贡献率。 From the perspective of social production, this paper studies the issue of income disparity by analyzing the income of the owners of the factors of production. The main reason for the widening gap between income distributions in a country is that the ratio of contribution of each factor of production to its contribution to social production is not equal, resulting in differences in income among owners of the various factors of production. If a country wishes to narrow its income gap, the contribution of each factor of production to social production must be adjusted according to its contribution to social production or the contribution of each factor of production to social production according to the input of each factor of production in the country.
