“跨界发表”:学术发明家的学术发表对其专利网络的动态演化影响

“Bounder-Spanning Publication”:The Dynamic Evolution Analysis of Academic Inventors Academic Publishing Behavior on Their Patent Networks

[目的/意义]“科学—技术”的知识融合和重组过程往往会因为面临一系列权衡抉择,但学界对于背后的机制还缺乏了解。[方法/过程]本文采用网络分析的随机行动者模型,对2011—2019年基因泰克公司的1339名专利发明人构成的专利合作网络进行了跨时段的网络演化机制分析。[结果/结论]本文发现了学术发明家在专利—论文跨界发表时发生的权衡抉择现象,在学术发明家发表论文后,学术发明家在专利合作网络中的合作倾向反而会下降。本文从“小世界性”“网络根植性”和“网络中介人”的角度分析了学术发表影响专利网络结构的3种演化机制。本研究有助于理解近年来逐渐引起关注的企业从事基础研究的现象,也为目前企业的科学研究参与提供了实证参考。

[Purpose/Significance]The process of knowledge integration and recombination in science and technology often faces a series of tradeoffs choice,but the academic community still lacks understanding of the underlying mechanisms.[Method/Process]This article used a stochastic actor-oriented model for network analysis to analyze the cross-temporal network evolution mechanism of patent cooperation network consisting of 1339 patent inventors from Genentech from 2011 to 2019.[Result/Conclusion]This article discovers the trade-off phenomenon that academic inventors make when publishing patents and papers across boundaries.After academic inventors publish papers,their tendency to collaborate in the patent collaboration network actually decreases.This article analyzes three evolutionary mechanisms by which academic publication affects the structure of patent networks from the perspectives of“small world”,“network rootedness”,and“network brokerage”.This study helps to understand the phenomenon of enterprises engaging in basic research that has gradually attracted attention in recent years,and also provides empirical reference for the current scientific research participation of enterprises.
