本文首先从技术能力演化的轨迹和技术能力积累的机制出发,研究内部途径和外源途径在技术能力演化中的互补作用。然后提出了技术能力形成的内外途径交替的螺旋运动模式,即在技术能力演化的每个阶段中,技术能力积累途径都经历了从外部技术源到内部学习的转换过程,这样就构成了技术知识外源与内部技术学习的三次循环。最后研究杭州制氧机厂在半个世纪中技术能力积累途径的演变过程。

This paper first focuses on the interaction and reinforce to each other of internal R&D and external knowledge in the process of technological competence evolution. Then the model of the two paths' circle action is put forward. In every phase of technological competence, the path of technological competence accumulation transforms from external knowledge assimilation to internal learning, these form three circles from external path to internal path. Finally, the paths of technological capability building of Hangzhou Oxygen-making Generator Manufacturer(HOGM) is studied.
