哈长城市群县域经济差异时空演变分析

Temporal-spatial Pattern of Economic Differences at Country Scale in Harbin-Changchun Urban Agglomeration

以哈长城市群为对象,通过对城市群内部经济的绝对差异和相对差异进行比较,分析城市群内部经济发展水平分异特点,并从时间和空间两个角度对经济发展空间差异结构进行了分析;通过空间自相关分析,以四个时间断面为基础,描述2000年以来哈长城市群县域经济发展水平的空间集聚特征.研究得出:哈长城市群内部经济发展水平上升显著,但是经济发展的绝对差异与相对差异均有扩大现象;空间集聚发展的态势从负相关转为正相关,各地域之间的关联性呈现逐渐增强态势;经济发展水平的空间集聚特征表现为低、高水平县市数量所占比重较大,南北地域分布两极分化特征明显,其中,北部地区较多县市发展水平较低,中部、南部地区发展较好.

Taking GDP per capita as the index of measurement,based on the analysis platform of geographical space and spatial autocorrelation,meanwhile,combining traditional analysis methods such as standard deviation, coefficient of variation and Gene coefficient. Taking Harbin-Changchun urban agglomeration as the object,through the comparison of the absolute differences and the relative differences within the urban agglomeration,the characteristics of the level of economic development within the urban agglomeration are analyzed from two angles of time and space. Through spatial autocorrelation analysis,based on four temporal sections,the spatial agglomeration characteristics of county economic development level since 2000 is described. The results show that the level of internal economic development in Harbin-Changchun urban agglomeration has risen significantly,but both the absolute and relative differences of economic development have expanded. The trend of spatial agglomeration development is changed from negative correlation to positive correlation,and the correlation a regions shows a gradually increasing trend.The spatial agglomeration characteristics of economic development level show that the polarization of distribution on number of cities and counties in low and high levels is obvious. The northern and southern regions are characterized by polarization,among which the northern areas are backward development,and the central and southern regions develop better.
