摘要
文章以京津冀城市群13个城市为研究对象,专利申请授权量为创新产出的衡量指标,2005-2015年为研究时序,运用探索性和证实性空间数据分析方法,对京津冀城市群创新活动空间集聚及其影响因素的空间异质性演化过程进行分析。结果表明:城市群创新产出地理集聚特征明显,空间分异显著,京津存在虹吸效应,城市群不存在收敛特征;R&D经费支出、经济密度、第三产业占比和对外开放程度对创新产出的影响均是正向作用,但存在空间异质性,同一影响因素在不同地区对创新的影响不同。不同地区根据影响因素的空间异质性采取不同政策措施促进地区创新水平提升,缩小京津冀城市群创新空间分异。
The paper, by taking 13 cities of Beijing-Tianjin-Hebei urban agglomeration as the research object, the number ofpatent application authorization as the measure of innovation output and 2005 to 2015 as the research time, applying explorato-ry and confirmatory spatial data analysis methods, makes an analysis on the evolution process of spatial heterogeneity of spatialagglomeration of innovation activities and its influential factors in Beijing-Tianjin-Hebei urban agglomeration. The resultsshow that: The geographic agglomeration characteristics of innovation output of urban agglomeration are obvious, and the spa-tial differentiation is remarkable. There is a siphon effect in Beijing and Tianjin, and there is no convergence characteristic ofurban agglomeration; R&D expenditure, economic density, the proportion of the tertiary industry and the degree of opening tothe outside world all play positive roles in innovation output, but there exists spatial heterogeneity. The same influential factorhas different effects on innovation in different regions. Different regions should adopt different policies and measures to im-prove regional innovation level and narrow the innovation spatial differentiation of Beijing-Tianjin-Hebei urban agglomerationaccording to the spatial heterogeneity of influencing factors.
