Abstract
As a global innovation capital and industrial cluster representative, Silicon Valley affects the whole world for its scientific and technological innovation. Patent co-citation can be used as information carrier to identify the core technology patents and evaluate technical similarities between enterprises in industrial clusters. In this paper, we carry out industrial clusters analysis of Silicon Valley from the perspective of patents co-citation. Based on the Derwent patent database, a patent co-citation network analysis is carried out for top 150 high-tech enterprises in Silicon Valley to identify the industrial clusters in that region from 2001 to 2017. Through the analysis of industrial clusters, we can see the emerging industry development and different industrial clusters in Silicon Valley, and discover the connections of companies between different high-tech industries.
