A Study On The Regional Difference Of Urban And Rural Income Gap In China’s Minority Areas

China is a developing country, compared with the developed countries, the economic base is relatively weak. With the development of reform and opening to the outside world, farmers living standards gradually improved, but whether from many aspects such as economic development and financial development, urban development speed far faster in rural development speed, which led to the gradual widening of the income gap between urban and rural areas. Especially for the minority areas, the level of economic development lags behind other provinces, it is urgent to change this situation, narrowing the income gap between urban and rural areas is imminent. From the point of view of minority area as a whole, regional difference of income gap between urban and rural areas of study covers not only of urban and rural areas of two different groups of gap, but also covers the differences in urban and rural income gap between regions and to narrow the income gap between urban and rural areas throughout the region and promoting coordinated regional common development has important significance.Firstly on the basis of data source calculated in ethnic minority areas in different regions between urban and rural areas, the relative income gap, and in different regions of urban and rural areas is relatively income gap situation analysis; and then through the generalized entropy index(GE) index method to overall income inequality between city and country, regional gap between decomposition. Again according to the state space model to extract the common impact factor of income gap between urban and rural areas and the regional characteristic factor and the several factors are the empirical study on the influencing factors. Finally the vector self regression model of variance decomposition process to calculate the influencing factors of regional total factor and regional characteristic factor contribution rate, and relative interpretation and analysis. The results show that:(1) whether it is compared to the overall income gap between urban and rural areas and regions, showed a rising trend.(2) from both urban and rural areas and between regions of the point of view, the gap between urban and rural areas, the gap between regions has great influence on the overall income gap.(3) the level of economic development on the common factors of influence coefficient highest, showing similar to the "inverted U-curve" curve; industrial structure on the common factors of influence factor is also very high, decreasing trend in recent years; urbanization level on the common factors of the influence coefficient of positive and negative cross effect of showing and in recent years the influence coefficient of negative; the level of financial development on the common factors of impact of changes in the magnitude of is larger, and in recent years there is a rising trend; the factors of human capital on the common factors always smaller.(4) the income gap between urban and rural areas of the autonomous region in regional characteristics and the factor of influence factors of the contribution rate is different, Inner Mongolia autonomous region characteristic factor is mainly caused by the economic development level and industry structure; Xinjiang characteristic factor is mainly by the level of financial development and economic development level; Tibet characteristic factor is mainly caused by the level of economic development and industrial structure level of development; Ningxia and Guangxi characteristic factor influencing factors are similar, mainly due to the level of development of the industrial structure.According to the empirical results, according to the empirical study results are presented for some policy suggestions. One is to optimize the impact indicators, narrowing the income gap between urban and rural areas within the region; second, balance the development of the region, narrow the gap between regions. The limitations of the study are pointed out, and the prospects for the future are also pointed out. The last is a summary of the paper.
