松花江流域(吉林省段)区域经济差异研究

Study of regional economic disparity in Songhua River basin( the part in Jilin province)

以县域为研究单元,人均GDP为测度指标,利用SPSS16.0和ArcGIS9.3作支撑,对2001—2011年松花江流域吉林省段区域经济差异的时空格局进行初步探究.结果表明,1)2001年以来流域区域经济极化、经济总体差异均呈缩小趋势,区域内差异是区域整体差异的主要贡献者;2)流域上、下游经济差异较大,但经过多年发展,经济空间格局发生较大变化,松原次级经济增长极逐渐形成,经济空间结构由梯度分布转变为长吉、松原组团的"双核"结构;3)资源条件、产业结构和政策因素等是造成流域区域经济差异的主要原因.

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：l ）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.
