Abstract The Eastern enlargements of the European Union (EU) since the early 2000s have included post-transitional economies at a lower level of development than the existing member states and thus, have significantly affected the East-West migration flows and labour markets on both sides. This has provided a distinctive opportunity to study the effects of liberalisation and to identify economic factors leading to migration flows with the purpose of enabling better estimations of future migration trends. In this research, a panel data analysis with pair of country fixed effects and time fixed effects is used to explore several pull and push factors of the East-West EU migration flows in the period from 2000 to 2017. Results indicate that emigration rate responds rather quickly to the changes in GDP per capita and unemployment rate of the youth population in immigration country, with statistically significant elasticity coefficients, suggesting that international migration contributes significantly to adjusting the labour supply to fluctuations in economic activity.

欧盟扩大之后的移民决定因素：面板数据分析

摘要自2000年代初以来，欧洲联盟（EU）的东部扩张包括过渡后经济体，其发展水平低于现有成员国，因此对东西方的移民流动和双方的劳动力市场产生了重大影响。这为研究自由化的影响和确定导致移民潮的经济因素提供了独特的机会，目的是能够更好地估计未来的移民趋势。在这项研究中，使用了一组国家固定效应和时间固定效应的面板数据分析，以探索2000年至2017年期间东西方欧盟移民流动的几个推动因素。
