Based on a long and consistent data set of real per capita GDP in Chian,1952 — 2003,employing f_ER, f_W, f_TW and f_KZ indexes,the regional economic polarization trends and Orientations in China have been scrutinized. The study results show that,on the whole,the overall long tendency of regional economic polarization across inter-provincial regions in China was increasing and decreasing in turn over time during 1952—2003. During the transitional period 1978 — 2003,in the long run,although the tendency of regional polarization had been intensified obviously,the polarization trend became not so serious as it was before. And the polarization orientations were along the inland-coastal and less-highly urbanized dimensions, which showed the regional economic inequalities in inland-coastal and less-highly urbanized dimensions in China, 1952 — 2003,were characterized with significant polarizations.
