摘要
运用空间统计学对中国1990～2002年期间省域R&D活动的空间分布进行了空间探索性数据分析。对全局的Moran'sI统计分析表明:省际R&D之间存在着空间自相关;Moran散点图进一步揭示了省际R&D活动水平的总体差异。对局部的Moran'sI分析确定了R&D活动的空间集聚模式及空间演变态势,说明经过十几年的发展,中国省际间R&D水平总体差异在空间上确实有不同程度的减少,但R&D活动的地域性很明显。
Based on methods of exploratory spatial data analysis, this paper analyzes R＆D activities in China from the perspective of spatial statistics. Our results show strong evidence of spatial autocorrelation in the provincial R＆D, and furthermore, a total difference of provincial R＆D level is disclosed by using Moran scatter plots. Finally, local measure of spatial autocorrelation with local Moran＇s I reveals that provincial R＆D activities tend to be spatially clustered in nature. All this suggests that a total difference of provincial R＆D level has been reduced spatially after more than 10 years of development, and that provincial R＆D activities are obviously localized.
