Local and nonlocal knowledge typologies: technological complexity in the Irish knowledge space

This paper advances a measure of knowledge complexity to analyse for Ireland whether more complex knowledge is generated by local or foreign firms. Information on assignees, technological structure and global ownership contained within a recently developed Irish patent database forms the basis for distinguishing between technologies developed by local and nonlocal firms. Thereafter, our knowledge complexity index uses a modified bipartite network to link these technologies to their country of origin, i.e. local or nonlocal. Our results indicate that the most complex technologies tend to be produced in a few diverse regions. Furthermore, the majority of complex knowledge is generated in technology classes where the share of foreign activity is greater than local firms.
