【摘要】：以长江经济带130个城市作为空间观测单元,以专利申请量作为衡量各城市创新能力的指标,对长江经济带各城市2000~2014年创新能力的空间分布及演化进行分析。研究表明:(1)从时空总体演变来看,长江经济带城市创新能力表现出非常显著的区域差异,且呈现出由渐进式集聚向缓慢扩散的发展趋势。(2)从空间聚类分布来看,长江经济带创新能力较高的城市主要分布在东部的长三角地区和中西部的省会城市地区。(3)从空间分布演变来看,长江经济带城市创新能力表现出显著的空间自相关,空间分布集聚态势增强,但在地理空间的差异上呈现出缩小的趋势,且不同集聚区在不同空间范围上都表现出一定的扩展与收缩态势。(4)城市的经济发展水平、创新主体、创新投入及创新基础设施的差异性,对长江经济带城市创新能力呈现出不均衡的空间分布产生重要影响。
[Abstract]:Taking 130 cities of the Yangtze River economic belt as the space observation unit, the amount of patent application is taken as the index to measure the innovation ability of each city. The spatial distribution and evolution of innovation ability of cities in the Yangtze River economic belt from 2000 to 2014 are analyzed. The urban innovation ability of the Yangtze economic belt shows a very significant regional difference, and shows a development trend from progressive agglomeration to slow diffusion. (2) from the perspective of spatial clustering distribution. The cities with higher innovation ability in the Yangtze River economic belt are mainly distributed in the eastern Yangtze River Delta region and the central and western provincial capital city area.) from the perspective of spatial distribution evolution. The urban innovation ability of the Yangtze River economic belt shows significant spatial autocorrelation, spatial distribution and agglomeration enhanced, but the geographical spatial differences show a trend of narrowing. And different agglomeration areas in different spatial scope all show a certain expansion and contraction situation of economic development level, innovation main body, innovation investment and innovation infrastructure differences. It has an important influence on the urban innovation ability of the Yangtze River economic belt.
