地缘政治冲突、经济制裁和国际知识流动
Geo-political conflicts, economic sanctions and international knowledge flows
摘要：
我们以2014年乌克兰危机以来欧盟与俄罗斯之间的政治经济紧张局势为案例研究，探讨敏感的国际知识流动如何应对地缘政治冲突。我们的计量经济学分析基于涵盖1995年至2018年间超过5亿份科学出版物和800万份国际联合出版物的综合数据。我们的研究结果表明，从2014年开始实施的欧盟制裁和俄罗斯的反制裁对欧盟国家和俄罗斯之间的双边国际科学联合出版率产生了显着的负面影响。根据所选择的对照组和所考虑的部门，效应大小范围为15%至70%。还观察到影响随着时间的推移而增加。
英文摘要：
We address the question how sensitive international knowledge flows respond to geo-political conflicts taking the politico-economic tensions between EU-Russia since the Ukraine crisis 2014 as case study. We base our econometric analysis on comprehensive data covering more than 500 million scientific publications and 8 million international co-publications between 1995 and 2018. Our findings indicate that the imposition of EU sanctions and Russian counter-sanctions from 2014 onwards has significant negative effects on bilateral international scientific co-publication rates between EU countries and Russia. Depending on the chosen control group and sectors considered, effect size ranges from 15% to 70%. Effects are also observed to grow over time.
