广东省区域创新活动空间差异分析——基于探索性空间数据分析(ESDA)

Spatial differences of regional innovation activities disparities in Guangdong Province based on ESDA

在对广东省21个地级市区域创新活动进行探索性空间数据分析(ESDA)中,以新产品产值作为创新活动的代理变量,计算2000-2008年各年的人均新产品产值Moran′sI统计值表明,分布存在显著的正向空间自相关关系,即空间集聚现象。结合Moran散点图与LISA研究分析得出,广东省区域创新活动不仅存在空间自相关现象,还存在空间差异现象,同时,广东省区域之间存在明显的区域创新活动知识溢出。

According to the studies of regional RD activities in 21 citis in Guangdong on ESDA,the Moran′s I statistics for output value of new products between 2000 and 2008 show that there is a significant positive relationship.The number of per capita output value of new products is not random distributed;the area with higher（lower） estimated value is also adjacent to other areas with higher（lower） estimated value.Combining the Moran′s scatter diagram and LISA analysis comes out that in Guangdong,the per capita output value of new products not only exhibits the phenomenon of spatial autocorrelation,but also the phenomenon of spatial difference.Overall it is a core-periphery structure.The core is Pearl River delta,the rich zone,and the mountain area and the east wing,the low-level agglomeration zone form the periphery.It shows the positive knowledge spillover effect of regional RD activities in Guangdong.
