FDI在华区域分布的探索性空间数据分析

Exploratory Spatial Data Analysis on Distribution of FDI in China

运用探索性空间数据分析方法对1983-2007年FDI在我国各省区的分布格局及空间动态演变进行了研究。Moran’sI指数揭示了长期以来FDI地区分布整体正向空间相关的特征,具有相似FDI水平的地区在地理上趋于集聚,而不是随机分布。Moran散点图显示了FDI在东部地区高水平集聚和西部地区低水平集聚的空间格局。局部空间联系指标进一步评估了局部空间相关的形式和显著性程度。

Based on a sample of Chinese provincial per capita FDI over 1983 to 2007, Moran＇ s I statistic reveals positive global spatial autocorrelation, which is persistent over the whole period： regions with relatively high （low） per capita FDI are and remain localized close to other regions with relatively high （low） per capita FDI, and the spatial distribution of regional per capita FDI is not random. Moran Scatter plots show that most of the eastern provinces are in the high- high quadrant and the western ones in the low- low quadrant, which suggests that there are two distinct spatial clusters of high and low values of per capita FDI. Moreover, LISA statistics identify and assess the significant presence of local spatial autocorrelation.
