京津冀省域创新效率差异演化与空间计量分析

以京津冀3个空间单元为研究对象,建立综合指标体系,利用熵值法计算2005—2015年省域创新效率,运用ESDA和CSDA分析法,详细刻画京津冀创新效率差异的时空演化特征,并分析扩散效应与回流效应在京津冀内部之间的流向。结果表明:京津冀省域创新效率存在正向全局空间自相关,空间聚集特征明显;创新效率在省域之间地理分异特征显著,北京和天津同属于HL型区域,河北则属于LH型区域,基本已形成"中心-外围"的空间格局,不存在收敛特征;创新效率空间结构属于空间滞后模式,存在扩散效应,但扩散效应主要存在于京津之间,河北受京津扩散效应不明显,反而由于回流效应导致与其差距不断增加。

The Innovation Efficiency Pattern Evolution and Spatial Econometric Analysis of Beijing,Tianjin and Hebei

Taking Beijing,Tianjin and Hebei as the research object,the paper establishes comprehensive index system,uses entropy method to calculate the provincial innovation efficiency from 2005 to 2015 by using ESDA and CSDA analysis method combined with Geoda and ArcGIS software to analyse innovation efficiency of the regional differences and its evolution process and analyze the flow direction of the diffusion effect and the backflow effect in Beijing,Tianjin and Hebei.The results show that the innovation efficiency has positive global spatial autocorrelation and spatial clustering is obvious;the innovation efficiency of the regional geographical differences between the different features is significant,Beijing and Tianjin belong to the same H-L region;Hebei belongs to the L-H region.During the research period,the regional innovation efficiency of Beijing,Tianjin and Hebei Province has basically formed the "center-periphery" spatial pattern,the backflow effect is dominant in this region and there is no convergence characteristics;the innovation efficiency of spatial structure is spatial lag model and has diffusion effect,but the diffusion effect exists mainly between Beijing and Tianjin,Hebei under the influence of Beijing and Tianjin is not obvious.On the contrary,due to the backflow effect,the gap between Hebei and Beijing-Tianjin is growing.
