Abstract:With the theory of knowledge network, there exists a phenomenon of agglomeration in the knowledge network. The evolution of knowledge network agglomeration is proposed. By theoretical research, the article analyses the composition and formation of knowledge resonance, knowledge translation and knowledge sequence. As the case study of Henan Changyuan crane machine knowledge network, it thinks that the evolutional direction of agglomeration in knowledge network is affected by knowledge resonance, translation and sequence. By case discussion, it is founded that the evolution of agglomeration in knowledge network appears non-liner characters with the effects of three different forces. It has experienced five evolutional stages, namely, local agglomeration, agglomeration, local block, block, re-agglomeration, thus promoting the continuous upgrading of knowledge network.
