基于分位数回归的经济增长与城乡差距的关系研究

The Relationship of Economic Growth and Urban-Rural Gap in ChengDu——Based Quantile Regression Method

以人均地区生产总值的对数增长幅度来衡量经济增长,以城镇居民消费水平与农村居民消费水平的比例作为城乡收入差距衡量指标,通过建立不同分位数下的分位数回归模型,揭示在经济增长的不同水平下,经济增长对城乡差距影响的变化。结果表明:当经济的水平比较快速时,经济增长的幅度变大,从而导致贫富差距加大,财富集中到城市中,城乡差距的扩大。政府必须防止经济增长由偏快转为过热,对通货膨胀进行严格的控制,使城乡收入差距的缩小与经济增长和谐一致发展。

In this paper, the logarithmic growth rate of per capita GDP is used as a measure index of the economic growth.The consumption ratio of urban residents and rural residents is used as a measure index of the urban-rural gap.Through the establishment of different quantile model, the impact of Urban-rural gap under the different levels of economic growth is shown and analyzed.The results show that： when the level of economic developments rapidly, the economic growth rate becomes larger, the gap between the rich and the poor increase, the wealth concentrate to the city, the urban-rural gap expand .The government must prevent economic growth from becoming overheated, control inflation strictly,, the urban-rural gap narrowed and economic growth will be Harmony.
