江西省外商直接投资(FDI)空间格局演变

Spatial structure of FDI distribution in Jiangxi Province

借助GIS的组织和提取空间数据、制图以及空间自相关分析方法,根据1997年、2007年江西省各县(市)外商直接投资FDI数据,通过几何分级方法得出江西省FDI总体上呈"十"字形空间格局;利用全局空间自相关的方法检验出江西省FDI空间分布具有显著的正自相关性;根据局域空间自相关系数,将江西省FDI分布的空间关联格局划分为高值正相关、高值负相关、低值正相关、低值负相关等4个类型。研究结果显示,江西省FDI空间分布具有显著的正自相关性,即具有高密度区域和高密度区域相邻接、低密度区域和低密度区域相邻接的趋势。

Thanks to the help of organizing and extracting spatial data, mapping and spatial autocorrelation analysis method of Arcgis and GeoDA, according to the data of FDI from 1997 to 2007, the ＂＋＂ differences in spatial pattern of Jiangxi Province was found by geometrical interval. Using the method of Global spatial autocorrelation, Spatial Correlation of FDI in Jiangxi Province was significant positive autocorrelation. According to local spatial autocorrelation coefficient, the spatial distribution pattern of Jiangxi FDI was divided to four types, such as high positive correlation, high negative correlation, low positive correlation, low negative correlation. The result shows that the spatial distribution of FDI has a significantly positive correlation, which is high-density and high-density region adjacent to the regional, low-density and low-density region adjacent to the regional trend.
