城乡移民 收入不平等 基尼系数
城鄉移民 收入不平等 基尼繫數
성향이민 수입불평등 기니계수
Rural-Urban Migration; Income Inequality; Gini-Coefficient
经典经济学认为，城乡移民（农民工进城）减少了收入不平等，但迄今并无严格的分析。本文从理论上讨论农民工进城对于以基尼系数衡量的收入不平等的影响，关键假设是把农民工看成一个独立的群体加以考虑。研究表明，农民工进城并不总是减少收入不平等；特别是在城乡移民早期，很可能增加收入不平等。本文还讨论了农民工进城以及户籍改革对于城镇内部、农村内部和城乡之间收入不平等的影响。
經典經濟學認為，城鄉移民（農民工進城）減少瞭收入不平等，但迄今併無嚴格的分析。本文從理論上討論農民工進城對于以基尼繫數衡量的收入不平等的影響，關鍵假設是把農民工看成一箇獨立的群體加以攷慮。研究錶明，農民工進城併不總是減少收入不平等；特彆是在城鄉移民早期，很可能增加收入不平等。本文還討論瞭農民工進城以及戶籍改革對于城鎮內部、農村內部和城鄉之間收入不平等的影響。

Classical theory predicts favorable effects of rural-urban migration on income inequality, while rigorous analysis has been absent. This paper develops a theory to explore those effects. Income inequality is measured by Gini-coefficient, and a key assumption regards migrant workers as a separate group. The migration often but not always reduces income inequality, and even tends to increase it at early stages of migration. The paper also discusses effects of migration and reform of household registration system on inequality within and between urban and rural population.
