Abstract
The literature on geography of innovation suggests that innovation outcomes depend on the type of knowledge base employed by firms. While knowledge bases are distinct categories with regards to the nature and the rational of knowledge creation, existing studies also stress that innovation usually involves more than one knowledge base.
In fact, new ideas often occur when analytical, synthetic and symbolic knowledge intertwines. It remains unclear, though, which combinations of knowledge bases are most conducive to innovation at the level of the firm, and how this is influenced by the knowledge bases available in the regional milieu.
