运用塞尔指数和区域基尼系数，发现我国区域创新能力在空间分布上具有明显的集聚特征，尤其是向经济发展水平高的东部地区集聚；运用σ收敛和β收敛，表明我国区域创新能力在变化趋势上总体表现为发散性，尽管东部和中部地区表现为收敛性；还运用多元回归和空间自相关等方法分析这种分布特征与变化趋势的成因，结果显示区域创新能力受经济水平、产业R&D投入强度、技术吸收能力、公共科研机构知识溢出水平等因素影响。

The characteristics of spatial distribution and changing trend of regional innovation capability in China are investigated by using Theil index and spatial Gini coefficient, σ-convergence, and β-convergence, respectively. And furthermore, multiple linear regression and spatial autocorrelation are employed to explore the determinants of regional innovation capability. The findings are demonstrated as follows: there exists evident agglomeration of regional innovation activities, especially clustering in the developed coastal region of China; as a whole, regional innovation capability shows a divergent tendency during the period of 1990 to 2007, in spite of there is a convergent trend in the east and the middle parts of China. The results also suggest that regional economic level, industrial R&D intensity, technology absorption capability, and spillovers from public R&D institutions are important determinants of regional innovation capability.
