Space-time Analysis on the Regional Economic Inequality and Polarization in China
使用2000-2010年地级市数据，通过数学公式量化分析中国区域经济不平等与极化的演变过程和格局，发现东部地区最显著，西部地区增长快，东北地区下降，中部地区低于全国但逐渐扩大。
On the basis of reviewing domestic and international regional economic inequality and polarization related research progress,this paper employs a series of foreign mathematical formulae of inequality coefficient and polarization index,and uses the prefecture-level administrative regions as study units,and 11 consecutive years(from 2000 to 2010) as a research period to quantitatively analyze the evolution process and pattern of regional economic inequality and polarization in China.The results show that the overall trend of nationwide regional inequality and polarization is basically the same in recent ten years,which shows the fluctuation trend.From the view of evolution pattern,the Eastern region economic inequality and polarization are more significant than other regions,the Western region economic inequality and polarization are increasing more rapidly,the Northeastern region economic inequality and polarization are showing a constant downward trend,and the central region economic inequality and polarization are lower than the nationwide and other three regions,but showing a gradually expanding trend.From the view of province area,most provincial internal inequality and polarization change in positive correlation.
