欧盟成员国、候选国家和全球伙伴之间科学合作的演变：2000-2024
Evolving scientific collaboration among EU member states, candidate countries and global partners: 2000-2024
AI总结：
研究分析了2000-2024年间欧盟成员国、候选国家和全球伙伴的科学合作演变，发现欧盟-14国家合作稳定，欧盟-13国家合作中等，候选国家合作较弱，且欧盟框架计划对合作有重要影响。
摘要：
本研究探讨了欧盟整合、全球化和地缘政治动荡如何影响不同欧盟成员国阶段的欧洲国家之间的科学合作。具体而言，它区分了2004年或之后加入欧盟的欧盟-14，以及欧盟候选国家。利用Scopus文章，本研究分析了欧盟成员国、候选国家和中国、拉丁美洲、英国、美国和俄罗斯之间的相对合作强度（RIC）。研究发现，欧洲集团内部的整合和与全球伙伴的合作正在增加，但等级结构仍然存在。欧盟-14国家是网络的核心，表现出稳定且紧密的合作，包括与英国的合作，尽管有脱欧。欧盟-13国家处于中间位置，显示出与欧盟-14的中等合作，但与自身集团和候选国家以及俄罗斯的合作更强。欧盟候选国家与欧盟-14的整合更弱，专注于内部联系和与欧盟-13和俄罗斯的联系。RIC在2012年和2018年分别达到峰值，对应于“地平线2020”和“地平线欧洲”周期，突显了欧盟框架计划的作用。与俄罗斯的合作在2014年后增加，仅在2022年后略有下降。对于欧盟-14，其与美国的合作超过。与中国的合作受到网络和文化限制，三大群体的强度相似。总体而言，资金和政策举措是稳定国际合作的关键。
英文摘要：
This study explores how EU integration, globalisation, and geopolitical disruptions have influenced scientific collaboration among European countries at different stages of EU membership. Specifically, it distinguishes between the EU-14, the EU-13, that joined the EU in 2004 or later, and EU candidate countries. Using Scopus article, the study analyses Relative Intensity of Collaboration (RIC) among EU member state, candidate countries and China, Latin America, the UK, the USA and Russia. Findings indicate increasing integration within European groups and with global partners, yet persistent hierarchical structures remain. EU-14 countries form the core of the network, exhibiting stable and cohesive collaboration, including with the UK despite Brexit. EU-13 countries occupy an intermediate position, showing moderate collaboration with EU-14 but stronger collaboration within their own group, with EU candidate countries and Russia. EU candidate countries demonstrate even weaker integration with EU-14, focusing on intra-group ties and links with EU-13 and Russia. RIC peaks in 2012 and 2018 for EU-13 and EU candidate countries correspond to Horizon 2020 and Horizon Europe cycles, highlighting the role of EU Framework Programmes. Collaboration with Russia increased following 2014 and only marginally declined after 2022. For EU-14, it exceeds collaboration with the USA. Collaboration with China remains limited due to network and cultural constraints, with similar intensity across all three groups. Overall, funding and policy initiatives are critical for stable international collaboration.
