This paper aims to give a theoretical introduction on onward migration and provide a review of empirical research on this topic in the EU. While there is a growing body of work on the topic, this still remains an under-researched phenomenon. Existing studies have looked at different, often overlapping, dimensions of onward migration and how it may be an effect of mobility capital or influenced by variables as diverse as economic crises, gender, country of origin, age and skills. In this article, we proceed by isolating some of these variables and identify common issues across research. The first section provides some defining points and conceptualizes different types of onward movement. The second section focuses on different dimensions of onward migration and highlights some key areas examined by research such as push and pull factors, different forms of capital including the role of EU citizenship and the economic crisis of 2008.

继续迁移和欧洲内部流动：批判性和理论性概述

本文旨在对继续移民进行理论介绍，并对欧盟在该主题上的实证研究进行回顾。虽然关于该主题的工作越来越多，但这仍然是一个研究不足的现象。现有研究着眼于迁徙的不同维度，通常是重叠的维度，以及它如何成为流动资本的影响或受经济危机、性别、原籍国、年龄和技能等多种变量的影响。在本文中，我们将分离出其中一些变量并确定研究中的常见问题。第一部分提供了一些定义点并概念化了不同类型的前进运动。第二部分侧重于向前迁移的不同维度，并重点介绍了研究审查的一些关键领域，例如推和拉因素，
