一从欧洲近代史来看,欧洲大陆是今天许多国家、特别是发展中国家移民向往的“移民的大陆”,曾经是输出移民或外迁移民的大陆。KlausJ.Bade教授认为,“欧洲移民外迁的目标地区主要是两个地区:一是通过陆路到东部俄罗斯及东欧国家;二是通过大西洋航线从欧洲大陆移民美洲大陆”1。 From the perspective of modern history in Europe, the mainland of Europe is the “continent of immigrants” longing for immigrants in many countries today, especially in developing countries. Once the continent of immigrants or immigrants, the continent was the continent. Professor Klaus J. Bade believes that “the target areas for the emigration of European immigrants are mainly two areas: one is by land to eastern Russia and the eastern European countries; the other is the migration of immigrants from continental Europe via the Atlantic route to the American continent”.
