The adoption process of refugees and expellees and their unification into society and economy in West Germany after World War II

第二次世界大战结束后，难民和被驱逐者从前德意志赖希东部流入德国西部和中部。该研究项目包括一个基于未发表的数据的验证附录，描述了他们在占领时期和联邦共和国德国早期（1945-1955）的适应过程。与此同时，分析了作为德国经济核心的鲁尔区所在的北莱茵-威斯特伐利亚州的煤炭工业与政府当局之间的关系，发现这些人的迁移，包括难民和被驱逐者的流入，以及他们在社会和经济中的融合，对战后德国经济的复苏起到了关键作用。它也与战后北莱茵-威斯特伐利亚的工业历史有着密切的关系。

After the end of World War II, refugees and expellees flowed into western and central Germany from the eastern part of the former German Reich. This research project consists of a verified appendix based on unpublished data describing their adaption process during the occupation period and the early period of the Federal Republic of Germany (1945-1955). At the same time, an analysis has been conducted on the connections between the coal industry and the government authorities of North Rhine-Westphalia, which includes the Ruhr district - the core of the German economy.It emerged that the migration of this population, involving inflows of refugees and expellees, and their unification into society and economy played a key role in the revival of the German economy after the war. It also had a close relation to the postwar industrial history of North Rhine-Westphalia.
