Migration studies have developed rapidly as a research field over the past decades. This article provides an empirical analysis not only on the development in volume and the internationalization of the field, but also on the development in terms of topical focus within migration studies over the past three decades. To capture volume, internationalisation, and topic focus, our analysis involves a computer-based topic modelling of the landscape of migration studies. Rather than a linear growth path towards an increasingly diversified and fragmented field, as suggested in the literature, this reveals a more complex path of coming of age of migration studies. Although there seems to be even an accelerated growth for migration studies in terms of volume, its internationalisation proceeds only slowly. Furthermore, our analysis shows that rather than a growth of diversification of topics within migration topic, we see a shift between various topics within the field. Finally, our study shows that there is no consistent trend to more fragmentation in the field; in contrast, it reveals a recent recovery of connectedness between the topics in the field, suggesting an institutionalisation or even theoretical and conceptual coming of age of migration studies.

映射迁移研究：一个研究领域时代到来的实证分析

在过去的几十年里，移民研究作为一个研究领域迅速发展。本文不仅对该领域的数量发展和国际化进行了实证分析，而且还对过去 30 年移民研究的主题焦点发展进行了实证分析。为了捕捉数量、国际化和主题焦点，我们的分析涉及基于计算机的移民研究领域主题建模。与文献中所建议的朝着日益多样化和分散的领域的线性增长路径不同，这揭示了一条更复杂的迁移研究时代到来的路径。尽管移民研究的数量似乎在加速增长，但其国际化进展缓慢。此外，我们的分析表明，与迁移主题内的主题多样化相比，我们看到了该领域内各种主题之间的转变。最后，我们的研究表明，该领域并没有出现更多碎片化的一致趋势；相比之下，它揭示了该领域主题之间最近恢复的联系，表明移民研究的制度化甚至理论和概念时代的到来。
