This paper provides new insights on the effects of the enlargement of the European Union (EU) and European integration by investigating the issue of scientific collaboration within the new EU member states -- the old EU member states. The question addressed is whether the EU membership following the two enlargement waves 2004 and 2007 has significantly increased the co-publication intensity of the new member states with other member countries. The empirical results based on data collected from the Web of Science database and Difference-in-Difference estimations point towards a conclusion that joining the EU indeed has had an additional positive impact on the co-publication intensity between the new and old member states and, in particular, within the new member states themselves. These results give tentative support for the successfulness of the EU's science policies in achieving a common 'internal market' in research. We also find evidence for early anticipation effects of the consecutive EU accession.
本文通过研究新欧盟成员国与旧欧盟成员国之间的科学合作问题，对欧盟扩大和欧洲一体化的影响提供了新的见解。所探讨的问题是，2004年和2007年两轮扩大后的欧盟成员国身份是否显著提高了新成员国与其他成员国的共同发表强度。基于从科学网数据库收集的数据和双重差分估计的实证结果表明，加入欧盟确实对新老成员国之间，特别是新成员国自身内部的共同发表强度产生了额外的积极影响。这些结果初步支持了欧盟科学政策在实现研究领域共同“内部市场”方面的成功。我们还发现了连续加入欧盟的早期预期效应的证据。
