基于不同空间尺度的陕西省区域经济差异研究

Study on the Regional Economic Disparity of Shaanxi Province Based on Different Spatial Scales

运用绝对差异、相对差异和泰尔指数T等指标,从陕西省不同空间尺度,对2001—2014年区域经济发展水平的差异程度进行了分析。结果表明:(1)从不同空间程度上看:空间尺度越小,差异程度越大,即县域>市域>区域。(2)经济发展快的地域,其内部经济发展差异越大;发展相对滞后的,其内部差异较小。(3)不同空间尺度的绝对差异呈现进一步扩大趋势;相对差异在波动中变化,相对发展率呈现出“北高南低夹关中”的倾斜趋势;区域间差异的贡献率大成为总体差异的来源,整体呈现出“扩大—缩小—扩大—缩小”的趋势。

Using indexes such as absolute disparity,relative disparity and Theil index (T),the degree of disparity of regional economic development levels from 2001 to 2014 was analyzed from different spatial scales in Shaanxi Province. The results show that (1) from the perspective of space,the smaller the spatial scale,the greater the degree of inequality,that is,the degree of inequality in counties is higher than that in cities which is higher than that in regions. (2) The regions with rapid economic development always encounter significantly diverse internal economic development and those lagging behind have less internal inequalities. (3) The absolute disparity of different spatial scales tends to further expand. The relative difference changes in fluctuation and the relative development rate inclines to be "high in the north and low in the south to clamp on the Guanzhong plain". In addition,the overall inequality is resulted from the high contribution rate of the inter-regional differences,and presents the trend of "expansion-reduction-expansion-reduction".
