本文以县(市、区)作为空间分析单元,以专利授权量作为创新产出指标,对1986-2014年长江经济带853个县域创新产出的时空特征进行ESDA分析。结果发现:(1)长江经济带创新产出的绝对差异在2001年前增长缓慢,其后增长迅猛,2012年后开始降低;相对差异呈现“增加—缩小—缓慢增加—缩小”的态势,其年度空间关联性呈增长趋势;(2)长江经济带创新产出县域分布呈现出分散、集中、相对集中扩散的态势,创新产出较高的县(市、区)为长三角地区地级市区、经济发达县(市、区)以及中西部地区省会城市市区;(3)显著空间关联类型总体格局稳定,局部变化明显,县(市、区)显著空间的关联类型以正相关类型为主,显著低低集聚关联类型占主导地位,低低集聚地区主要在西部地区,且有向中部扩展的态势;(4)长江经济带创新产出空间格局演变过程中,科技创新资源禀赋、教育水平与研发投入、技术溢出与扩散、政策与制度因素的作用较为显著。
In this paper, county (city, district) as the spatial analysis unit, with the amount of patent grants as innovation output indicators, ESDA analysis of the spatial and temporal characteristics of 853 counties in 1986-2014 economic output. The results showed that: (1) The absolute difference in the innovation output of the Yangtze River economic belt increased slowly before 2001, then increased rapidly, and then decreased after 2012; the relative difference showed the trend of “increase-decrease-slow increase-decrease” (2) The distribution of innovative output in the Yangtze River Economic Belt shows the trend of decentralized, concentrated and relatively concentrated proliferation. The counties (cities and districts) with higher output of innovation are in the Yangtze River Delta (3) The spatial pattern of significant spatial pattern was stable in general, with obvious local changes, and positive correlations were found in the correlation types of significant spatial scales in counties (cities and districts) (4) In the evolution of the spatial pattern of innovation output in the Yangtze River Economic Belt, the resources of technological innovation are endowed with the characteristics of low-low agglomeration and low-low agglomeration in the western region, , The level of education and research and development investment, technology spillover and proliferation, the role of policy and institutional factors more significant.
