基于不同空间尺度的山东省区域经济差异研究

Study on Regional Economic Disparity of Shandong Province Based on Different Spatial Scales

运用变异系数CV、泰尔系数T等指标,基于三大经济板块、17个市域、121个县域等不同空间程度,对1990年以来山东省区域经济发展水平的差异程度进行了分析。结果发现,空间尺度愈小,差异程度愈大,即县域间差异程度大于市域,市域大于板块,但从变化趋势看,板块间差异程度对全省经济发展水平差异的贡献度在提高。从三大板块内部看,鲁中地区经济发展水平差异程度大,鲁东和鲁南地区内部差异程度小。

Analyzing regional economic disparity is significant to both academic enquiry and government policy.The recent papers on economic geography imply that spatial scale has been playing an important role in the economic geographical processes.With the increasing availability of data,this paper employs Coefficient Variance and Theil Index to analyze the difference degrees of regional economic development in Shandong since 1990 sat diverse spatial scales,i.e.three major economic blocks,17 cities,121counties.The result shows that the smaller spatial scale,the greater difference degree there is——a decreasing sequence：counties,cities,blocks.But according to the trends,it is also discovered that the contribution of difference degrees among blocks to the difference of the economic development in whole province is increasing.For the three economic blocks,the middle part of Shandong Province brings out the greater difference degrees in economic development than those of the eastern and southern part of Shandong Province.
