[目的/意义]内卷现象改变着个体对于竞争压力的认知，催生出非理性的知识学习行为。基于SOR模型揭示知识断连产生的内在机理，识别知识断连与连接间的悖论关系，对理解知识断连并进行动态性干预以促进知识主体及社会的可持续发展有着重要意义。[方法/过程]基于数字断连相关研究提出知识断连概念，分析知识断连触发基础、反应过程及实施策略，在此基础上探讨知识断连的实践悖论并构建解悖框架。[结果/结论]多源条件刺激下产生过滤性、防御性和含混性知识断连3种行为反应，用以调节心理状态及内在感知；知识断连实践过程中存在着价值悖论、情绪悖论和认知悖论，表现为知识断连与连接的对立选择，引发个体的悖论思维；构建基于包容性接受、和合性适应和动态性协同3个过程的解悖框架，推动实现知识断连与连接的动态平衡与良性循环。

[Purpose/significance] The phenomenon of involution alters the individual's cognition of competitive pres⁃sure, generating irrational knowledge learning behaviors. Based on the SOR model, it is significant to reveal the intrin⁃sic mechanism of knowledge disconnection and identify the paradoxical relationship between knowledge disconnection and connection, so as to understand knowledge disconnection and intervene dynamically in order to promote the sus⁃tainable development of knowledge subjects and society. [Method/process] This study proposes the concept of knowl⁃edge disconnection based on digital disconnection related research, analyzes the triggering basis, reaction process and implementation strategy of knowledge disconnection, and explores the practical paradoxes of knowledge disconnection and builds a framework for solving the paradoxes on this basis. [Result/conclusion] There are three kinds of behavioral responses, namely filtered, defensive and ambiguous knowledge disconnection, to regulate the mental state and inner perception under multi-source conditioned stimuli. There are value paradoxes, emotional paradoxes and cognitive para⁃doxes in the process of knowledge disconnection practice, which are manifested in the opposing choices of knowledge
disconnection and connection, triggering individuals' paradoxical thinking. This study also constructs a paradoxes reso⁃lution framework that includes three processes: inclusive acceptance, harmonious adaptation, and dynamic synergy, in order to promote the realization of the dynamic balance and virtuous cycle of knowledge disconnection and connection.
