武汉市创新城区的空间格局演化研究

Research on Spatial Pattern Evolution ofInnovative Urban Areas in Wuhan

创新城区是城市创新活动聚集的功能性城市片区,对提升城市区域竞争能力具有重要作用。以创新网络理论为基础,运用空间自相关性分析和核密度分析对高新技术企业密集分布的武汉市进行了实证研究。首先利用核密度法分析武汉市高新技术企业在2011—2018年的分布变化,然后利用空间自相关性分析研究武汉市主城区创新网络的空间格局演化特征。研究表明,武汉市创新城区的空间分布经历了由主城区逐渐向外溢出,并从单一中心向创新走廊发展的演化过程,未来应从区域协同创新的角度统筹规划区域创新走廊和新一代创新城区。

The innovation city is a functional urban area where innovation activities gather in the city,and it plays an important role in enhancing the competitiveness of the city′s region.Based on the innovation network theory,this paper uses spatial autocorrelation analysis and kernel density analysis to conduct an empirical study on Wuhan,where high-tech enterprises are densely distributed.First,the kernel density method is used to analyze the distribution changes of high-tech enterprises in Wuhan from 2011 to 2018,and then the spatial autocorrelation is used to study the spatial pattern evolution characteristics of the innovation network in the main urban area of Wuhan.Studies have shown that the spatial distribution of Wuhan Innovation City has gradually evolved from the main urban area,and from a single center to an innovation corridor.In the future,the regional innovation corridor and the new generation of innovation urban areas should be planned from the perspective of regional collaborative innovation.
