从1931年日本帝国主义发动九一八事变开始,至战后几十年,对中、日双方在东北的兵力问题,国内外各种资料说法不一,至今尚无一个统一的准确的数字.笔者近几年在撰写中国大百科全书军事卷和中国军事百科全书有关东北抗日战争条目时,查阅大量中日双方的原始资料,经过综合研究和考证,现对这个问题提出辨证,请史学界专家学者指正. From the very beginning of the September 18th incident in 1931 when Japanese imperialism was launched to the decades after the war, various sources at home and abroad have different opinions on the issue of the troop strength of China and Japan in the Northeast. So far, they have not yet got a unified and accurate figure. In recent years, when writing the Encyclopedia of China Encyclopedia Military Volume and the Chinese Military Encyclopedia on the items of the Anti-Japanese War in Northeast China, the author consulted a large amount of the original materials of both China and Japan. After comprehensive research and research, I hereby present the dialectic of this issue. Scholar correction.
