Research on the Change of the Degree of Polarization in Urban-Rural Income in Central China
|Keywords||Income polarization Polarization Index Central Region Economic growth|
The problem of unequal distribution of income has been subject to the concerns of the community, and the the income polarization problem in recent years has begun to attract the attention of scholars, there are varying degrees of urban-rural income polarization, and the differences across regions, central China Regional static characteristics and dynamic spatial and temporal evolution of the urban-rural income polarization characteristics of the in-depth analysis, and to explore the long-run equilibrium relationship between the urban and rural income polarization and regional economic growth. I first use of the empirical data of the six provinces in central, urban-rural income polarization index (ER Index) of 88 prefecture-level city in the central region, according to the the ER Index of regional rank, and 88 in the central region will be on the basis of this ranking prefecture-level cities are divided into four categories according to the degree of polarization, are urban-rural polarization-hit areas, urban and rural areas the polarization more serious areas, urban and rural polarization generalization regions, urban and rural polarization significant areas. Then discuss the characteristics and spatial distribution of these four types of areas, and to analyze the economic development of the area of ??each type of polarization differences. Dynamic analysis section, select 2000 and 2009 at two points in time data from the prefecture-level cities (prefectures) domain, the provincial domain, as well as the type of polarization zone level analysis of the urban-rural income polarization of the central region in the past 10 years evolving dynamic characteristics. Finally, in the perspective of the overall level of the central region to explore the dynamic relationship between the urban and rural income polarization and regional economic growth. The main conclusions are: the central region cities (prefectures) domain of urban and rural incomes the polarization varying degrees, and the distribution is extremely uneven, there are significant regional differences in the central region provinces Province within the urban-rural income polarization degree of difference is also very prominent. The more serious areas of urban and rural polarization serious regional and urban-rural polarization is much larger than the number of urban and rural polarization generalization region and urban-rural polarization significant number of areas, from the spatial distribution characteristics see a large number of serious areas. Dynamic analysis found that the income of urban and rural residents of the central region of the city (state) polarization index certain degree of reduction in addition to a small number of prefecture-level cities, the vast majority of the prefecture-level cities showed varying degrees of growth, type of space distribution occurred significantly changes. Cointegration test found in the discussion of the relationship between urban and rural income polarization and economic growth, the existence of a cointegration equation, that is, between the two long-run equilibrium relationship between income polarization index and the GDP per capita.
