中共中央应对中东路事件的策略,实际上是以共产国际六大的“第三时期”理论为依据的。陈独秀三次致信中央,对中央处理中东路事件的策略以及大革命以来党的路线、方针和政策提出了尖锐的批评。传统观点对这三封信都持否定态度,认为这是陈独秀丧失革命立场,形成取消主义思想的重要标志。客观地分析,陈独秀的三封信尤其第二封信中虽然包含错误意见,但正确的、有价值的主张占主导地位。然而,当时的党中央认为这是陈独秀已沦为托派分子的标志,最终把它作为开除陈独秀出党的重要依据之一。 The CCP Central Committee’s strategy of responding to the Middle East Road incident is actually based on the theory of “the third period” of the six major Comintern nations. Chen Duxiu sent a letter to the Central Government three times, sharply criticizing the Central Committee’s strategy of handling the Middle East incident and the party’s line, principles and policies since the Great Revolution. The conventional view holds a negative attitude toward these three letters and considers this an important symbol of Chen Duxiu’s loss of revolutionary positions and the formation of the ideology of cancellation. Objectively speaking, Chen Du-xiu’s three letters, especially the second letter, contain incorrect opinions, but the correct and valuable propositions dominate. However, the party Central Committee at that time considered this as a sign that Chen Duxiu had become a leader of the Tu-faction and eventually regarded it as one of the important bases for dismissal of Chen Duxiu from his party.
