STUDY ON THE DIVERGENCE AND TEMPERAL-SPATIAL STRUCTURE OF REGIONAL ECONOMIC DEVELOPMENT IN JIANGSU PROVINCE

Since the 1980s, regional in equality in China has been one of the most important topics attracting scholars' attention both at home and abroad. However, most studies are based on macros regions and provinces, and have paid less attention to the trends and mechanisms of regional economic divergence within provinces. Jiangsu is a large province of nearly 74 million population, which economy has grown very fast since there forms. However, the divergence of regional economic development in this province became more and more obvious in 1980s and 1990s and should be paid necessary attention. According to the statistical analysis of regional economic development, especially in county level, in Jiangsu province, this article discusses the spatial pattern of regional economy, the process of the divergence change. This paper finds that absolute divergence is broadening and relative one fluctuating, and that regional economy and its growth rate affects its divergence change. Through the comparison with the change of per capita GDP in county-level, we find that the divergence is be coming divided. The economic divergence changes in county level express more difference to a certain extent. Regional economic development is closely related to its environments, such as regional economic strength, income, consume etc. Finally, the authors put forward some policy suggestions to adjust and control this economic divergence.
