Abstract:

The geographical flow of talents is affecting innovation activities worldwide, so the research on the spatial structure evolution of talent flows is particularly important.This article uses the 2014-2015 global list of highly cited scientists as raw data to retrieve the study and work experience of scientists, uses cities as the research scale, and uses the P-space model to build a highly cited Chinese scientist flow network. At the same time, uses quantile regression analyzes the impact of whether scientists in core cities are more productive. We found that: (1) The city network of highly cited Chinese scientists has the characteristics of a small-world network, and the network space structure presents a "Y-shaped" structure. China-U.S., China-Europe, and China-Australia are the main sides. (2) This article analyzes the source cities and the target cities in which scientists move, and finds that Beijing, Cambridge(UStates), Shanghai are the city with a high degree.(3) The distribution of scientists shows a trend of spreading with the development of the stage.(4) Scientists in core cities have more high-quality paper output. The increase in the degree of centrality of scientists' target cities has a greater impact on the output of scientists.Key words: highly cited Chinese scientists; talent flow; P-space model; quantile regression

摘要:

人才的地理流动正在影响着世界范围内的创新活动,对人才流动的空间结构及演化研究显得尤为重要。以2014—2015年全球高被引科学家名单为原始数据,对科学家的学习和工作经历进行检索,以城市为研究尺度,借助P-space模型构建高被引华人科学家流动网络,并利用分位数回归分析城市是否位于核心城市对科学家产出的影响。发现:①高被引华人科学家流动城市联系网络具有小世界网络特征,网络空间结构呈现以中国-美国、中国-欧洲、中国-澳大利亚为主要框架的“Y形”结构;②本文对科学家流动的城市出入度进行分析,发现北京、剑桥(美)、上海为高入度高出度城市;③科学家的分布随着阶段的发展,呈现扩散趋势;④位于核心城市的科学家有更多高质量的论文产出,科学家的迁入城市度中心性的提升对科学家的产出影响更大。
