收入差距的倒U型机制是内生的吗?

Is the Inverted U Shape Curve of Income Gap Really Endogenous?

本文采用非参数方法来考察理论研究当中,收入差距可能存在的内生倒U型机制。实证研究发现,经济增长、金融发展、教育发展、城市化与收入差距之间存在不规则的倒U型关系;在考虑了地理分布的前提下,国际贸易、FDI与收入差距之间仅存在较弱的倒U型关系。基于此,内生的倒U型机制不必然的存在于经济发展当中,政府还需要进一步调整政策来改善收入差距。

Basing on non of income gap. nomic Through growth, financial - parametric method, this paper studies existence on the inverted U shape curve the empirical study, there is irregular relation of inverted U pattern between eco- development, education development, urbanization and income gap; In given conditions, a weakly inverted shape curve exists between international trade, FDI and income gap. Therefore, the results show that the inverted U shape is not endogenous in reality, which suggests that in- come gap must be adjusted by government policies.
