城乡分割、收入不平等与金融发展——基于中国1978—2006时间序列数据的实证研究

Urban-Rural Segmentation,Income Inequality and Finance Growth

本文通过分析金融发展不平衡对收入不平等传导机制,采用Theil指数分解原理将中国1978～2006的总收入差距分解成城乡、城城和村村收入差距以考察我国的收入不平等程度,并在选用金融发展规模、效率、结构3个指标和控制变量的基础上考察了我国金融发展对收入差距的影响。研究表明:(1)金融发展规模和发展效率是城乡收入和城城收入差距的单向Granger原因,而与村村收入差距却互不为Granger原因;金融发展结构和城乡、城城以及村村收入差距三个指标互不为Granger原因。(2)金融发展规模和收入差距呈显著正相关,而金融发展效率和结构与其呈负相关;FDI会显著拉大收入差距。

On the base of the conduction mechanism between the imbalanced finance growth and income inequality, this paper analyzes the degree of income inequality by decomposing China＇s income inequality in the period from 1978 to 2006 into the Urban-Rural,Urban-Urban and Rural-Rural the three parts and makes the regression analysis with the index of the/inance growth scale,efficiency and framework. The results show that： （ 1 ）A single Granger causality exists between the finance growth scale and efficiency; However, no Granger causality exists between the finance growth and income inequality; （2） A positive correlation exists between the finance growth scale and efficiency; Also, a negative correlation exists between the finance efficiency and framework ; FDI would significantly enlarge the gap of the income inequality.
