Abstract

We investigate the role of both internal and external co‐inventor networks in regional diversification. The impact of co‐inventor networks on regional technological diversification is tested for a data set containing 1,495,699 patents in 643 technologies in 290 European regions at the NUTS‐2 level, between 1987 and 2016. Our results show that both internal co‐inventor network connectivity and external co‐inventor network linkages could benefit regional technology entry and prevent regional technology exit. However, too inwardly oriented or outwardly connected co‐inventor networks would hamper patent production. Regarding regional diversification, we find that both internal and external co‐inventor networks could facilitate the entry of related technologies and restrain the exit of complex technologies. This paper contributes to the literature by initiating the integration of the complexity dimension into analysing the role of co‐inventor networks in regional diversification. This research bears significant policy implications for the advancement of Smart Specialization Strategy in the European Union.

欧盟的关联性、复杂性和地区多样化：共同发明人网络的作用

我们研究了内部和外部共同发明人网络在地区多样化中的作用。共同发明人网络对地区技术多样化的影响是通过一个数据集来检验的，该数据集包含 1987 年至 2016 年间欧洲 290 个地区 NUTS-2 级别的 643 项技术中的 1 495 699 项专利。我们的研究结果表明，内部共同发明人网络连接和外部共同发明人网络连接都有利于地区技术进入，并防止地区技术退出。然而，过于内向或外向的共同发明人网络会阻碍专利生产。在区域多样化方面，我们发现内部和外部共同发明人网络都能促进相关技术的进入，抑制复杂技术的退出。本文在分析共同发明人网络在地区多样化中的作用时首次纳入了复杂性维度，为相关文献做出了贡献。这项研究对欧盟推进智能专业化战略具有重要的政策意义。

期刊介绍： ACS Applied Bio Materials is an interdisciplinary journal publishing original research covering all aspects of biomaterials and biointerfaces including and beyond the traditional biosensing, biomedical and therapeutic applications. The journal is devoted to reports of new and original experimental and theoretical research of an applied nature that integrates knowledge in the areas of materials, engineering, physics, bioscience, and chemistry into important bio applications. The journal is specifically interested in work that addresses the relationship between structure and function and assesses the stability and degradation of materials under relevant environmental and biological conditions.
