Abstract:

On the basis of growth polar theory, an evaluation system was built for understanding mechanisms and spatial discrepancies of economic polarization in central China during the period from 2001 to 2005 by means of generalized principal component analysis. It was shown that the factor of economic development production, factor of economic investment and factor of urbanization are key momentums which lead the polarization of economy in the central region of China, but their contribution to the polarization ranged from a high level to a low level. Further analysis on the variation of evaluation system revealed that the contribution rates of different indicators varied, and there were 10 indicators which were keycontrolled variables. The analysis of projective combination of the two components revealed a weak effect of economic investment on economic production; so the efficiency of economic production should be heightened. Synthetic analysis on alterations revealed that polarization in the central region was not significant, but its degree became gradually intensified. Therefore, to improve polarization system, some provinces such as Hubei, Hunan and Jiangxi with a higher polarization degree in the region should be given much more support.

Key words: the central region of China, economic polarization, polarization discrepancies, generalized principal component analysis
