摘要本文以中国地级及以上城市单元为空间尺度,从Web of Science核心合集数据库中手工整理2019年所有城市间合作论文数据,对中国城市间科研合作网络结构特征与网络生成问题进行研究。研究发现,中国城市间科研合作网络呈现出多级分层特征,具有小世界性且网络效率不高的特征。聚焦三大城市群的科研合作网络一体化分析发现,京津冀、长三角和珠三角城市群之间的科研联系邻近度要低于他们各自内部的科研联系邻近度,这意味着三大城市群的城市更多是在城市群内部建立科研联系,城市群之间的科研联系邻近度仍有待提升。进一步的QAP回归分析发现,地理邻近性、高校、经济发展水平、科研实力以及社会邻近性差异是影响中国城市间科研合作网络生成的重要因素。
Abstract：This paper based on the urban units at prefecture level and above in China as the spatial scale,manually collects the data of all inter-city collaboration papers in 2019 from the Web of Science core collection database,and examines the structure and formation of China's inter-city research collaboration network.We find that inter-cities collaboration network presents a multi-level hierarchical feature,with a small world,but the network efficiency is not high.The analysis of the integration of the scientific research collaboration network focusing on the three major urban agglomerations reveals that the proximity of scientific research connections among the Beijing-Tianjin-Hebei,Yangtze River Delta,and Pearl River Delta urban agglomerations is lower than the proximity of their respective internal scientific research connections,which means that more cities in the three urban agglomerations establish scientific research connections within urban agglomerations,and the proximity of scientific research connections between urban agglomerations still needs to be improved.Further QAP regression analysis shows that geographic proximity,universities,economic development level,scientific research strength,and differences in social proximity are important factors that affect the formation of China's inter-city scientific research collaboration network.
