| 摘 要： | 在空间统计分析的应用中,空间权重矩阵的设定对空间自相关的分析结果有较大的影响。通过构建基于邻接关系和空间距离的两大类共计14组空间权重矩阵,以河南省县域经济为研究对象,计算全局和局部两种空间自相关指数,研究空间权重矩阵对区域经济空间自相关分析的影响。结果表明:1)一阶车矩阵比二阶车矩阵能更好地度量河南省县域经济的空间分布,表明河南省县域经济的空间自相关性主要发生在边界直接相邻的区域之间,空间依赖效应从邻域不断向外辐射的现象不明显。2)合理应用空间距离矩阵的关键是能够正确设定阈值距离d,当40 km<d<50 km时,河南省县域经济呈现显著的空间自相关性。3)由郑州市以及围绕郑州的环形区域共同构成了河南省唯一的大面积高GDP值聚集区域,省会城市的经济外溢现象明显;豫东北的鹤壁市和新乡市为低GDP值聚集区域。

| Abstract: | In the application of GIS spatial statistical analysis,the spatial weight matrix has major impact on the results of spatial autocorrelation analysis.In this paper,based on adjacency relation and spatial distance rules,we construct two kinds of spatial weight matrices.Taking the county economy of He′nan Province as the research object,calculate the global and local spatial autocorrelation indices,and study the influence of spatial weight matrix on the autocorrelation analysis of regional economic.The results indicate that:(1)The first-order Rook matrix is more powerful to measure spatial distribution of the county economy in He′nan Province than the second-order Rook matrix.It shows that the spatial autocorrelation of the county economy in He′nan Province mainly occurs between the areas directly adjacent to the boundary,and the phenomenon that the spatial dependence effect radiates continuously from the neighborhood is not obvious.(2)The key to the rational application of the spatial distance matrix is to setting the threshold distance d correctly.When 40 km<d<50 km,the county economy of He′nan Province presents significant spatial autocorrelation.(3)Zhengzhou City and the circular area surrounding it constitute the only large high-GDP-aggregated area in He′nan Province,and the economic spillover effect of provincial capital cities is obvious.Hebi City and Xinxiang City in northeastern He′nan Province are low-GDP-aggregated areas. |
