摘要
根据5739条创新主体兴趣点(POI)数据,利用文献查阅、核密度、空间自相关等方法,厘清广州市创新空间的发展脉络、格局特征和集聚差异,并利用“城市人”理论和“四因说”探讨了创新空间发展的影响因素。结果表明:1)广州市创新空间经历了点—面—带的进程。2)广州创新空间形成“一主多节点”的空间格局,极化与扩散趋势并存。3)广州创新空间的集聚特征存在明显的类别差异和行政区差异。4)创新空间与创新活动人员的相关性较高;高校、科研机构和孵化器等是创新活动人员集聚的第一动力,并自我极化;空间集聚带来负向接触机会增加,促进了创新活动人员远离“中心”聚居(业)以及创新空间的扩散;创新产出效益导向推动了创新空间向生态网络发展。
Based on 5739 items of POI data in Guangzhou,the development process,agglomeration pattern and difference characteristics of innovative space are clarified by using Kernel Density Estimation(KDE)and spatial correlation analysis.The forming mechanism of spatial characteristics developed is explored on the basis of“Homo urbanicus”Concept and“four-cause theory”.The results show the following four conclusions.Guangzhou’s innovation space had experienced the development process of“point—area—belt”.The innovative space of Guangzhou forms a pattern of“one main and multiple nodes”,and polarization and diffusion trends exist simultaneously.Innovative spatial agglomeration features have significant differences in categories and regions.The matching degree between innovation space and innovation activity personnel is high.The carrier,colleges and universities,scientific research institutions play important roles in attracting innovative activity personnel,with the self-polarization characteristics appeared in the later stage.Spatial agglomeration increases the negative contact opportunities,which promotes the innovation activity personnel to stay away from the“center”and the diffusion of innovative space.Innovation output benefit-oriented promotes innovation space to become an eco-system.
