| 摘 要： | 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。 |

| Abstract: | This article analyzes the spatial distribution of innovation outputs—measured by the number of patent authorization—in the Yangtze River Economic Belt, using exploratory spatial data analysis (ESDA) method, based on the statistical data of 853 county-level cities from 1986 to 2014.The results are as follow: (1) The absolute difference of innovation output growth of the Yangtze River Economic Belt slowed before 2001, followed by a rapid growth in 2012, then began to decrease again. But the relative difference showed an increase-decrease-increase slowly-decrease trend, with increasing annual spatial correlation; (2) Innovative outputs in the Yangtze River Economic Belt counties showed dispersion, concentration, relative concentration spatial patterns. Counties/districts with higher innovation outputs were the urban districts of prefectural-level cities, economically developed counties, and the urban districts of provincial capital cities in the midwest. (3) The overall pattern of significant spatially correlated type areas was stable, while local changes were significantly. Positive correlation type was dominant at the county level, especially the significant low-low correlation type. Low-low correlation areas were mainly in the western region, but showed a tendency to extend to the central area. (4) Resource endowment, education level and R & D investment, technology spillover and diffusion, and policy and institution played a significant role in the process of change of innovation output spatial pattern in the Yangtze River Economic Belt. |
