摘要
要创新空间从单中心向多中心演化是科创城市发展的必然趋势,把握其规律是合理配置空间资源的重要依据。中国城市创新空间的多中心结构并不是单纯的市场选择,而是深受政府主动干预的影响。借鉴尺度重构理论,提出中国城市多尺度分异的基本特征,认为政策性新区、战略性新城等尺度重构方式改变了特定地区的权力关系和区位优势,创新企业在多尺度分异的格局中选择性集聚,推动了创新的多中心演化。以南京高新技术企业为研究样本,分析了国家级开发区、多功能新城和国家新区3种典型驱动力作用下的创新多中心演化过程。在高质量发展的新阶段,科创城市应动态调整尺度重构的策略,从刺激增长的增量供给转向优化创新生态的存量提升。
The evolution of innovation spaces from a single center to multiple centers is an inevitable trend in the development of science and innovation cities.Understanding this pattern is crucial for the rational allocation of spatial resources.The multi-centric structure of innovation spaces in Chinese cities is not solely a result of market selection but is also influenced by proactive spatial interventions by the government.Drawing on the theory of rescaling,this paper proposes the basic characteristics of multi-scale differentiation in Chinese cities.It argues that methods of rescaling,such as policy-driven new districts and strategic new towns,have altered power relations and locational advantages in specific regions.Innovation enterprises selectively cluster within the framework of multi-scale differentiation,driving the multi-centric evolution of innovation.Using high-tech enterprises in Nanjing as a research sample,the paper analyzes three typical processes of multi-centric innovation evolution driven by national development zones,multifunctional new towns,and national new districts.In the new stage of high-quality development,science and innovation cities should dynamically adjust their rescaling strategies,shifting from stimulating growth to optimizing the innovation ecosystem.
