运用ESDA方法对1997-2009年我国341个城市专利产出的时空演变特征进行分析;在此基础上构建空间计量模型,对我国城市专利产出的空间俱乐部收敛特征进行检验,并探讨其形成机制。研究结果表明:我国城市专利产出的空间自相关特征十分显著,且空间依赖程度在考察期内持续增强,由此带来城市专利产出空间差异在全国层面趋于发散。然而,在依据空间依赖模式进行分组的区域内部却表现出相异的时空演变特征。在H-H和L-L两个"空间俱乐部"内部,城市专利产出均呈现趋同迹象,但H-H组趋同特征不具显著性,同时组间专利产出差距不断扩大。研究在一定程度上揭示了空间异质性、局域地理溢出对专利产出整体发散和多稳态趋同的贡献和推动作用,并在此分析的基础上提出了相应的对策建议。
Abstract
Using the methods of exploratory spatial data analysis(ESDA), this paper analyzes the spatial distribution and dynamic changes of patent outputs in China, by studying 341 prefecture-level cities from 1997 to 2009. Then, the paper examines the spatial club convergence hypothesis of patent outputs by using spatial econometrics model, and finally explores the formation mechanism. The ESDA analysis using the Moran's I gives the strong evidence of spatial autocorrelation of patent outputs among cities, and the aggregation level has increased steadily over the past years. However, in the H-H and L-L groups, with the growth and the degree of aggregation increase, the difference of patent outputs between the two groups continues to expand and then form two "spatial convergence clubs". The empirical results show that the spatial heterogeneous and local geographic spillovers factors contribute to the features of overall differentiation and local multi-steady-state of regional patent outputs in China. Finally, this study presents some references valuable for analyzing spatial structure and policy-making.
