《历史学习》2002年第6期李友焱老师《中日民族矛盾上升为社会主要矛盾的时间》一文,认为中日民族矛盾上升为主要矛盾的时间为1935年华北事变。对于30年代中日民族矛盾何时上升为主要矛盾,史学界一直有争议,目前尚无定论。笔者认为,中日民族矛盾上升为主要矛盾的时间为1931年九 In “Learning for History” in the sixth issue of 2002, Teacher Li Youxi wrote “The Time of Ethnic Conflict between China and Japan has Become a Major Contradictory of the Society,” and it is believed that the rise of the Sino-Japanese ethnic contradiction as the main contradiction occurred in the 1935 North China Incident. Regarding the rise of the national contradiction between China and Japan in the 1930s as the main contradiction, the historians have always been controversial. At present, there is no definitive conclusion. The author believes that the time when the ethnic contradictions between China and Japan rose to the main contradiction was 1931.
