日本学界和国内学界对日本大正时期出现的民主主义思潮一直持有肯定态度,但是对于该思潮的瓦解却鲜有研究。大正民主主义思潮的瓦解中不可忽视的重要因素之一就是1925年通过的治安维持法。通过考察治安维持法与大正民主主义思潮逐步趋向瓦解的关系,从而为理解近代以来日本内政外交提供一个新视角。 Japanese academics and domestic academics have always held a positive attitude toward the democratic trend of thoughts during the Japanese Taisho period, but few studies have done about the collapse of this trend of thought. One of the important factors that can not be ignored in the disintegration of the trend of the Dazheng democracy is the law on maintaining public order passed in 1925. By examining the relationship between the law and order maintenance and the gradual tendency of the Dzong democracy, this paper provides a new perspective for understanding Japan’s internal affairs and diplomacy since modern times.
