新疆区域经济差异测度及其空间尺度效应研究

空间尺度效应可有效揭示区域经济差异系统特征。本文运用锡尔系数及Moran′s指数对新疆区域经济差异进行了多维尺度测算,研究发现,新疆三大区域、各地州市和县(市)层面的锡尔系数值与Moran′s指数值均存在显著差异,表明新疆区域经济差异存在空间尺度效应。对空间尺度方差分解结果表明,新疆三大区域、各地州市和县(市)层面的尺度方差逐级升高,同时三级尺度对新疆总体经济差异的贡献率也随尺度的降低而增大,其政策意蕴在于,未来新疆区域经济协调发展政策的制定,应根据不同空间尺度经济差异特征,建立科学合理的分级政策体系。

Spatial scale effect is an effective measure to reveal an important means of regional economic disparities in system features . This paper uses Theil and Moran＇s index to estimate Xinjiang regional economic disparities from muhidimensional scales.The study found that Xinjiang three regions,local city and county levels of Theil coefficient and the value of Moran＇s index values were significantly different,indicating Xinjiang regional economic disparities exists spatial scale effect .Spatial scale effects variance decomposition results show that the variance of the three scales Xinjiang region, local city and county levels progres- sively increased, while the third dimension to the overall economic differences Xinjiang contribution rate increases with re- duced scale. Its policy implication is that the future of the Xinjiang regional coordinated development policy should be based on the characteristics of different scales of economic differences, to establish a scientific and rational system of grad- ing policy.
