现有有限的关于FDI影响能源强度的研究均从时间维度进行,忽略了FDI的空间外溢效应。本文利用空间自相关方法论证了FDI的空间特性。在此基础上,运用空间回归模型方法计量分析了FDI对能源强度作用的空间关系。基本结论是:(1)FDI具有显著的空间溢出效应;(2)不仅对本地区能源强度,FDI通过溢出效应对周边地区能源强度的降低也有明显的作用;(3)无论对本地区还是周边地区,FDI集聚对能源强度的作用在逐年增强。
Numbered studies about the effect of FDI on energy intensity focus on temporal but no spatial which can't show FDI's character of spillover effect. The regional characters of China 29 provincial FDI are verified through the Moran I index. Based on it, the spatial effect of FDI on energy intensity is analyzed by spatial regression model. According to the analysis: (1) The spillover effect of FDI is evidently. (2) Besides host region, FDI also can spread to adjacent regions by spillover effect. (3) The force of FDI to energy intensity is more powerful these years.
