以东方汽轮机火电技术追赶历程为研究案例，采用事件路径分析方法，基于外部响应和内部自发的学习驱动力，剖析国内企业动态调整双元学习闭环主导逻辑的过程构型。研究发现：国内企业可以围绕“技术改造→复制重构”的学习主轴，由外至内地调整双元学习闭环主导逻辑,实现技术自立自强。首先，企业在外部响应的核心驱动下，构建利用式学习主导的双元学习闭环（技术引进—技术改造—复制重构），完成基础能力建设；随着技术能力的累积，企业以复制重构为关键支点主动打破既有路径，推进技术自立；最后，企业依托内部自发驱动，重构探索式学习主导的双元学习闭环（技术改造—复制重构—自主研发），实现技术自强。

Taking the technological catch-up process of Dongfang Turbine in the field of thermal power technology as a case study, this paper adopts the event-path analysis method to analyze the process configuration of Chinese enterprises dynamically adjusting the dominant logic of their ambidextrous learning loops, based on the learning drivers of external response and internal spontaneity. The study finds that domestic enterprises can adjust the dominant logic of their ambidextrous learning loops from the outside in, revolving around the learning axis of “Technology Modification → Imitative Reconstruction”, to achieve technological self-reliance and self-strengthening. First, driven primarily by external responses, the enterprise constructs an exploratory learning-dominated ambidextrous learning loop (technology acquisition—technology modification—imitative reconstruction) to complete the construction of foundational capabilities. With the accumulation of technological capabilities, the enterprise actively breaks the existing path using imitative reconstruction as a key pivot, thereby advancing technological self-reliance. Ultimately, relying on internal spontaneous drivers, the enterprise reconstructs an explorative learning-dominated ambidextrous learning loop (technology modification—imitative reconstruction—independent R&D) to achieve technological self-strengthening.
