An Empirical Study Of The Influence Of The Regional Income Convergence From Population Chagnes

Since the reform and-opening up,China achieved remarkable development. The total value of China’s GDP in2008reached30.067trillion yuan, nearly18%share of contribution to the GDP of the world’s. China has become the world’s third largest economy. China’s nominal GDP was higher than Japan’s for almost$404.4billion in2010, the GDP average exchange rate has achieved$5.8791trillion, China has become the second-largest economy.Demographic factors is one of the elements of economic development, the relative population change and population movement is one of the motives affect the income gap. the increase in the proportion of the population of high-income areas associated with the reduction of the proportion of the population in low-income areas, and that high-income population increase in the proportion of the cost of reducing the proportion of low-income population. The relative change in the substance of the Chinese population in the study periods, and the population of the inter-provincial flow, changes in the distribution of the provincial,can well explain the convergence rate of per capita GDP between the provincesWith economy growing, regional population accounts for a share of the national population is also changing, the scale of population movements is expanding, the change of the population share and population movement can affect the trends of per capita income convergence This concern is not only in the domestic market but in the international arena has also been endless debate. On the impact of demographic changes and population movements on the convergence of per capita Scholars has different opinions. one is that demographic changes and population movements have a significant role to reduce regional disparities, and another view is that promoting regional population movements can not narrow the gap, Instead the regional gap is widening.Based on this backgrounds, this article will analysis the effect of on regional income convergence from the population relative change and population movement. First of all, this paper will analyze per capita GDP gap using the Theil index and the coefficient of variation, and this paper will analyze the per capita GDP gap by empirical research.we will prove that there is a convergence trend of income and per capita income in the study period. Followed, we will analyze the impact on income convergence by relative changes in population and population movements, the paper will point out that the contribution of relative changes in population income convergence can not be ignored. Finally, in this paper, we will analysis the impact of population mobility on regional income convergence.The paper is divided into five parts. The first part, review on the research of relationship of domestic and foreign population and income gap. The debate of income convergence effect by Relative changes in population and population flow were divided by neoclassical theory and endogenous growth theory. In Neoclassical growth model, investment marginal rate of return is degressive, so economic growth ensure to the stable in a particular value, the per capita output remain unchanged. Every economic unit (countries or regions) of the specific conditions is different, so steady-state value will also be different from each other. The process of Income tending to steady state is called income convergence.The second part of the paper mainly studies the per capita GDP convergence situation. In this part, first of all, explain the connotation of income convergence, then, use the Theil coefficient and coefficient of variation to analysis per capita GDP convergence characteristics, finally, by using a panel data model, empirical analyze the convergence situation and trend of the per capita GDP in China.The third part of the paper mainly analyzes how the relative changes of the population affect the convergence of per capita GDP. In this part, first of all, to descriptive the population dynamics (population relative change), illustrate how the population dynamics influence the convergence of income. Then, by the empirical analysis, studying how population relative change affect per capita GDP, at last, through the shift-share (shift-share) analysis to analyze the influence of per capita GDP convergence by the change of the provinces population share, so as to analysis the influence of per capita GDP convergence process.In the fourth part of the paper, we analyzes the influence of population flow on convergence of income by empirical analysis. First, analyze the present situation of the population flow, then, by using the statistical analysis software, we go through the empirical research and analysis on how population flow affect the income convergence.In the fifth part of the paper, according to the empirical results, we can draw the conclusion, and we can puts forward policy Suggestions, we can provide some methods and ideas on how to effectively play population action to narrow income differences.
