【摘要】：科技创新作为当今社会经济增长的核心驱动力,直接决定着一个国家与区域经济发展的速度与质量,科技创新空间布局优化,对于活化区域经济系统,改善区域发展的不平衡与提升国家综合实力有着重要的意义。在世界城市研究理论与方法的基础上,构建科技创新搜索趋势综合指数,搭建起省域间科技创新空间网络,借助社会网络分析(SNA)方法,对我国省域间科技创新关联及空间结构进行了多维度研究探讨,通过权重网络分析、枢纽网络分析以及节点核心度分析等多项结果表明,我国东—中—西各区域间及区域内部科技创新发展呈现出显著的不均衡特征,地理与流动空间不同视角下的区域科技创新空间分布差异化特征各异,从整体来看,以东部沿海经济带省域为核心的科技创新空间布局基本形成,黄河经济带、长江经济带的廊道效应逐渐突显,少数中西部省域科技创新表现突出并形成新的增长点;从网络分析视角出发,在以往科技创新分布研究的基础上,进一步揭示了省域科技创新空间的网络特征演变规律。
[Abstract]:Scientific and technological innovation, as the core driving force of social and economic growth, directly determines the speed and quality of a country's and regional economic development, the optimization of space layout of scientific and technological innovation, and the activation of regional economic system. It is of great significance to improve the imbalance of regional development and enhance the comprehensive strength of the country. On the basis of the theory and method of world city research, this paper constructs the comprehensive index of scientific and technological innovation search trend, builds the spatial network of scientific and technological innovation among provinces, and analyses the method of SNA-based social network. This paper discusses the relationship and spatial structure of science and technology innovation among provinces in China. The results show that, through the weight network analysis, the hub network analysis and the node core degree analysis, etc. The development of science and technology innovation among and within the eastern, central and western regions of China shows significant disequilibrium characteristics, and the spatial distribution of regional scientific and technological innovation is different from different perspectives of geography and flowing space. The spatial distribution of scientific and technological innovation with the eastern coastal economic belt as the core is basically formed, the corridor effect of the Yellow River economic belt and the Yangtze River economic belt is gradually prominent, and a few central and western provinces show outstanding scientific and technological innovation and form new growth points. From the perspective of network analysis and on the basis of the previous research on the distribution of scientific and technological innovation, this paper further reveals the evolution law of the network characteristics of the scientific and technological innovation space in the province.
