长江中游城市群科研人才空间集聚分析

Spatial Agglomeration Analysis of the Research Talents in the City Group in the Middle Reaches of Yangtze River

随着创新驱动发展战略的实施,科研人才在创新过程中的作用显得愈发重要。基于2006~2015年长江中游城市群的中国科技核心期刊论文作者数据和专利发明人(发明专利)数据,运用基尼系数、泰尔指数、空间密度分布和探索性空间分析方法,对上述科研人才的空间分布以及集聚程度进行了分析。结果表明,在长江中游城市群内,科研人才分布集中于区域中心城市,且分布随时间变化呈集聚性增加特征;此外,论文作者和专利发明人在城市群内的时空分布也呈现了不同的特征。

With the implementation of the innovation driven development strategy, the role of the research talents in the process of innovation is becoming important. In this study, based on the number of paper authors and the patent applicants in the city group in the middle reaches of the Yangtze River during 2006 to 2015, we used the Gini coefficient, Theil index, the distribution of spatial density and exploratory spatial data analysis (ESDA) method to analyze the spatial distribution and spatial agglomeration of basic research talents. The results indicate that the distribution of research talents has obvious spatial agglomeration in regional central cities, and shows the characteristics of increasing agglomeration with time. Moreover, the paper authors and the patent applicant present different spatial agglomeration characters in the study region.
