Abstract:

By selecting some county-level administrative districts as the study units and using SPSS16.0 and ArcGIS9.3,we analyze the spatial and temporal patterns of regional economic disparity in Songhua River basin on the basis of per capita GDP during the period from 2001 to 2011. The results show that:1)the total economic disparities and polarization at county level have decreased,and the integral economic disparities are contributed by the inside disparities; 2)the disparity between the upper and lower reaches greatly changed after the developments during these years,Songyuan as a secondary economic growth pole formed gradually,and the spatial distribution changed from the gradient distribution to a "dual-core" structure which consists of Changchun-Jilin and Songyuan; and 3)resource, industrial structure, and policy are the main causes of the regional economic disparity.

Key words: regional economic disparity, Theil index, Songhua River basin(the part in Jilin province)
