发布时间：2018-10-26 08:34

【摘要】：基于2003~2013年城市专利数据采用基尼系数、趋势面分析、空间动态面板数据模型等方法探讨了中国城市技术创新能力的空间分布和影响因素。研究发现:1中国创新能力高的城市高度集聚在沿海三大区域及内地的区域中心城市,随着时间推移,创新能力在空间上呈现扩散的趋势。城市技术创新能力的空间相关性逐渐增强,推动了创新的区域扩散和空间溢出。2发明专利、外观专利和实用新型专利的创新水平依次降低,空间集聚程度依次提高,空间相关性依次提高。3固定效应面板数据的空间滞后模型和空间Durbin模型的计量结果发现,城市技术创新能力存在显著的空间溢出效应,邻近城市技术创新能力的提升有助于提升该市的创新能力。政府支持、工业基础、高等教育资源、创新投入、经济外向度显著影响城市技术创新能力水平的提升,且政府支持和城市高等教育资源对城市技术创新能力的影响出现增强趋势。
[Abstract]:Based on the urban patent data from 2003 to 2013, Gini coefficient, trend surface analysis and spatial dynamic panel data model are used to discuss the spatial distribution and influencing factors of the technological innovation ability of Chinese cities. It is found that: 1 the cities with high innovation ability in China are highly concentrated in the three coastal regions and the regional central cities in the interior, and with the passage of time, the innovation ability tends to spread in space. The spatial correlation of the ability of urban technological innovation is gradually strengthened, which promotes the regional diffusion and spatial spillover of innovation. 2 the innovation level of the patent of invention, the patent of appearance and the patent of utility model decrease in turn, and the degree of spatial agglomeration increases in turn. The results of spatial lag model and spatial Durbin model show that there is significant spatial spillover effect in urban technological innovation ability. The upgrading of the technological innovation capability of neighboring cities will help enhance the innovation ability of the city. Government support, industrial base, higher education resources, innovation input and economic extroversion significantly affect the upgrading of urban technological innovation capability. Moreover, the influence of government support and urban higher education resources on the ability of urban technological innovation is increasing.
