The Quantile Regression Analysis On Urban Residents’ Income Gap Intergenerational Transmission

With the rapid growth of China’s economy, the imbalance of income distribution has led to many contradictions and conflicts, and the income distribution gap is very serious. Income distribution gap will cause the widening gap between the rich and the poor, which is not conducive to social toward "effort will have harvest" fair direction. Income inequality between people of different generations the intergenerational income elasticity is also the important influencing factor of income gap, so more and more scholars began to explore intergenerational income elasticity, the parent and offspring income curing phenomenon, and discuss the internal mechanism of influence of intergenerational income elasticity,which provide powerful basis for economic development. China is a country with a relatively complicated regional economic structure. The economic situation is changing every year. Different income levels have different economic characteristics. The income structure of urban residents and rural residents also have great differences. But previous research only on the overall were the intergenerational income elasticity analysis, does not take into account the different phenomenon of intergenerational transmission of different income groups, and there is a sample selection is not uniform, length of time to study problems. There exist a sample selection is not uniform, the study time is insufficient and so on. Therefore, this paper selects 24 years of urban residents’income in 1988,1995,2002,2007,2012 to better explain the intergenerational income elasticity in different periods of time in China; Using quantile regression to study the intergenerational income elasticity of different income levels; The elasticity of intergenerational income elasticity of rural residents and the intergenerational income elasticity of high income groups are more accurate; At the same time, it studies the influence of internal mechanism in different income groups on the intergenerational income elasticity, and puts forward policy recommendations.The following ideas are as follows:The first step is to study the intergenerational income elasticity; The second step, depending on income levels with different ideas,u-sing the quantile regression method to study the different points of the urban resident’s income elasticity; The third step is to study the change trend of the intergenerational income elasticity of the rich; The fourth step is to study the influence of the internal mechanism on the inter generational income at different points. The study shows that the research on the Overall intergenerational income elasticity can not effectively represent the intergenerational income elasticity of different income levels; After the reunification, the intergenerational elasticity from the left tail inverted u-shape changes to traditional u-shaped, the middle and higher income groups changes in intergenerational income mobility, after the 0.6 site, reduce intergenerational income after increasing trend,reached the lowest in 2012; However, the intergenerational income elasticity of the rich showed a trend of increase after decreases and then increases first with the increase of the year, in 2012, has a very high intergenerational income elasticity, wealth is still concentrated in the hands of a few people. To change this state, it is needed to deepen the reform of the related system and increase the mobility of the inter generation income. In this paper, we also study the internal mechanism of the intergenerational income elasticity. At the high points, the intergenerational elasticity of the father and son is greater than the daughter. From years of research, the intergenerational elasticity coefficient between father and son transform from the inverted u-shaped trend into a u-shape; The impact of higher education fathers’income on their offspring is lower than those with low educational background, that is, the high degree of father’s family, the lower income elasticity coefficient, the greater mobility of intergenerational income; the intergenerational elasticity coefficient between the father with Party membership and the son is larger, especially in the high income levels, curing is now more serious.
