东北地处边疆,其文化具有汉族与少数民族交融特点,而在近现代东北亚的政治发展中,充分体现出其上层建筑性质。东北不是民族自治区域,但文化的民族性是现代东北发展中的深层意识形态问题。因此,树立马克思主义民族观对认识日本对东北的文化侵略以及建设东北亚经济共同体都有着深远意义。 Northeast China is located in the frontier and its culture has the characteristics of integration of Han nationality and ethnic minorities. However, in the political development of modern Northeast Asia, it fully embodies the nature of its superstructure. Northeast is not a national autonomous area, but the national character of culture is a deep ideological issue in the development of modern Northeast China. Therefore, to establish the Marxist concept of nation has far-reaching significance in understanding Japan’s cultural aggression against the Northeast China and building the Northeast Asian Economic Community.
