湖南省城市创新能力空间分布、演化及溢出效应

Spatial distribution,evolution and spillover effect of urban innovation capacity in Hunan province

随着经济与科技的发展,城市创新能力逐渐成为城市发展的主要驱动力,成为城市和国家获得竞争优势和能够快速发展的重要因素。以湖南省14个地级市为例,从创新投入、创新产出及成效、创新人才及科教资源、产业技术创新能力和开放协同水平等5个方面,研究2009—2018年湖南省各地级市城市创新能力发展水平及其空间分布、演化特征,引入空间计量模型(SLM,SEM),分析城市创新能力对经济发展的空间溢出效应。结果表明,湖南省各地级市城市创新能力提升明显,空间差异整体不断缩小,空间集聚态势有所减弱。湖南省城市创新能力存在明显的由西向东逐渐增强的地带性,长株潭城市群是省内创新发展的核心区。城市及邻近地市城市创新能力的提升均对经济发展有正向溢出效应。

With the development of economy and science and technology,urban innovation ability has gradually become the main driving force of urban development and an important factor for cities and countries to gain competitive advantages and rapid development.Taking 14 prefecture-level cities in Hunan province as examples,the development level spatial distribution and spatial evolution characteristics of urban innovation ability of prefecture-level cities in Hunan province from 2009 to 2018 were discussed from five aspects:innovation input,innovation output and effectiveness,innovative talents and science and education resources,industrial technology innovation ability and the level of openness and collaboration.The spatial econometric model(SLM,SEM)was useded to analyze the spatial spillover effect of urban innovation ability on economic development.The results show that,The city of Hunan province urban innovation ability had improved significantly,the overall spatial had been continuously reduced,and the spatial agglomeration situation had weakened.The city innovation ability had obvious zonality gradually increasing from west to east,and the Chang-Zhu-Tan city group was the core area of innovation development in the province.The improvement of urban innovation ability in cities and neighboring cities had a positive spillover effect on economic development.
