民国时期,关内北方人民掀起了一场声势浩大的“闯关东”移民运动,成为二十世纪世界移民史上的“奇迹”。移民潮在调节民国时期人口分布,解决灾民生存问题的同时,也给东北三省的农业、工商业、文化、边防以及东北社会未来的发展变化带来了深远的影响。 During the period of the Republic of China, people in northern Guanzhong set off a massive immigration movement to “break into the east of Guandong” and became the “miracle” in the history of immigrants in the 20th century. The migration wave has far-reaching effects on the population distribution in the period of Republic of China and the settlement of the survivals for the victims, as well as on the future development and changes of agriculture, commerce and industry, culture, frontier defense and northeast China in the three northeastern provinces.
