China Stock Income Gap

In the current research literature, mainly in the residents’ annual income based onthe measure of income inequality, research shows that the upward trend in recentyears, the Gini coefficient, one of the objectives of the government is currentlyworking to narrow the income gap. In the disposable income of residents, the annualincome is just one part also includes the retained income before. Examine the incomegap, not only to examine the flow value of the income gap, but also examine the stockvalue of the income gap, the stock income residents to better reflect economicstrength, the stock of the income gap between the true sense of the income gap. In theprocess of accumulation of annual income into the stock of income, net of trafficrevenue leakage of consumption deducted from income, and thus need to study theimpact of consumption to income inequality.This paper first reviews a variety of algorithms measure of the income gapbetween the index and the Gini coefficient measure of the stock of the income gapbetween research on this basis, the stock is defined income gap, stock Gini coefficientalgorithm analysis the stock of the income gap between the amount of changes can bedecomposed into a catalytic effect and the dilution effect. The study found that therelationship between flow income and the stock of the income and sources of incometo total income consistent, the main difference is that the concentration index and theGini coefficient in the calculation of the sort.. In order to solve this problem, thispaper has taken the use of packet data to calculate the Gini coefficient, also to beinnovative in the group by using quantile grouping method, so that you can effectivelyresolve the centralized index and the Gini coefficient differences, making each of theyears the Gini coefficient can be added eventually get stock Gini coefficient. Studieshave shown that stock Gini coefficient is the weighted value of the Gini coefficient,the weight of the revenue for each of the sum of the ratio of the total revenue.Analysis of the influencing factors of the stock of the income gap, the first ofconsumption (revenue leakage) the flow income gap through the panel data model,studies show that the rate of consumption and income was negatively correlated. Onthis basis, the analysis shows that this consumer phenomenon will widen income gaps,residual income income gap is greater than the income gap of the flow of income.Further, the paper analyzes the impact of urbanization rate, the share of income of urban and rural areas and urban and rural per capita income of the stock of income,stock income trends, analysis shows that the income gap between the stock on thedevelopment trend of inertia, adjust the speed lag.The basis of theoretical research, the results of the theoretical study of empiricalresearch, in the process of empirical research using interpolation method to solve theproblem on the selection and estimates of the income distribution function, while theuse of statistical simulation method to overcome the sampling on obstacles. Empiricalstudies have shown that in the1995-2011period, the consumer further expand theannual urban income gap, the Gini coefficient of income of urban residents increasedby an average of52.85%, before deduction of consumption In2011, for example, theGini coefficient of0.3310, less post-consumer the Gini coefficient of0.4048. Thispaper calculated the the1978-2011stock income gap, the2011stock Gini coefficientof0.444, since2009, the Gini coefficient has declined, but the stock of income Ginicoefficient has not declined, indicating the current the stock of the income gapbetween inertia and hysteresis, respectively, to quantify the catalytic effect and thedilution effect. Finally, the results of this study summarizes the conclusions of thisstudy, the corresponding policy recommendations.
