城乡收入差距与经济增长关系的实证研究——基于中国1978-2007年数据的协整检验与脉冲响应分析

Empirical Research on the Relationship between Urban-rural Income Inequality and Economic Growth——Co-integration Test and Impulse Response Analysis Based on China's Data of 1978-2007

对中国1978-2007年数据的实证研究结果表明:城乡收入差距与经济增长之间存在着长期稳定的双向因果关系;城乡收入差距只在短期内对经济增长产生影响;而经济增长并不会自动导致城乡收入差距的缩小,相反,经济增长在中长期内还会进一步加大城乡收入差距。

The result of empirical research based on China＇s Data of 1978-2007 indicates that, there is long-term equilibrium relationship between urban-rural income inequality and economic growth, and economic growth is the granger reason of urban-rural income inequality, while urban-rural income inequality is also the granger reason of economic growth. Urban-rural income inequality only effects economic growth in short term and economic growth doesn＇t automatically reduce urban-rural income inequality, but conversely broadens further the urban- rural income inequality in long term.
