摘要
以2015年中原城市群30个城市为研究对象,通过构建区域创新能力评价指标体系,运用主成分分析法测算中原城市群的城市创新能力,利用修正后的引力模型探讨了中原城市群的创新空间联系结构,并结合断裂点公式及最大引力线模型,借助ArcGIS10.5软件进一步作可视化分析。结果表明:郑州在中原城市群的创新空间联系结构中处于绝对核心地位,但是其创新辐射范围仅局限于周边地市;中原城市群创新能力空间分布出现两极化现象;中原城市群创新空间联系结构存在明显的“核心-边缘”特征;地理邻近、技术临近、制度临近对中原城市群创新空间联系的形成起着重要作用。
This paper takes the 30 cities in Central Plains Urban Agglomeration in 2015 as the research object, constructs the evaluation index system of regional innovation ability and uses principal component analysis method to measure the innovation ability of the 30 cities in Central Plains Urban Agglomeration. Based on this, it uses the modified gravity model to explore the innovation spatial linkage pattern in Central Plains Urban Agglomeration, and then combines with the fracture formula and the maximum number of gravitational lines to further visualize the innovation spatial linkage pattern in Central Plains Urban Agglomeration based on the ArcGIS 10.5 software. The research has found that: Zhengzhou is in an absolute core position in the innovation spatial linkage pattern of Central Plains Urban Agglomeration, but its innovation radiation range is limited to surrounding cities;The spatial distribution of innovation ability of Central Plains Urban Agglomeration appears polarized;The innovation spatial linkage pattern in Central Plains Urban Agglomeration is characterized by the "core-edge" innovation network feature;Geographical proximity, technology proximity, and system proximity play important role in the formation of the innovative spatial linkage pattern of Central Plains Urban Agglomeration.
