基于ESDA—GIS的黑龙江省区域经济差异研究

摘要

文章以黑龙江省81个县（市、区）为基本空间单元，在ArcViewGIS软件和GeoDA空间统计分析软件的支持下，利用2009年黑龙江省县域人均GDP数据，对黑龙江省县域经济差异进行分析，分析结果表明：黑龙江省2009年总体经济差异较大，经济重心、人口重心和几何中心均有较大偏移，总体上黑龙江省2009年经济空间差异较大；全局Moran’s I指数为0．3876，空间自相关特性明显，经济发展水平相似的地区在空间上集中分布。在此基础上绘制了局域Moran’sI散点图和LISA集聚图，并采用空间插值获得局域I值分异图。%Taking the 81 counties （cities, districts） of Heilongjiang Province as basic spatial cells, this paper analyzes the spatial dynamics of regional disparities at the county level in Heilongjiang Province by analyzing per capita GDP data in 2009 with the support of ArcView GIS and GeoDA software. Empirical results show that the center of population and GDP have a significant offset with the center of geometry. The overall country level spatial disparities of regional economy in Heilongjiang Province is sig- nificant in 2009, and the global Moran＇s I is 0. 3876, which indicates that there are significant positive spatial autocorrelation of per capita GDP in Heilongjiang Province. That is the relatively high （low） developed county tends to be located nearby other height（low） developed counties more often than expected due to random chance. Local Moran＇s I scatter plots and LISA（ local Indicators of Spatial Association） cluster map have been used to test the local pattern of the Heilongjiang economic development.
