【摘要】It has been argued that innovation increasingly depends on external knowledgesources. It is still unclear if relations to particular knowledge sources or to a broad variety ofsources matter for innovation. Also, there is a debate on the issue which spatial levels are mostrelevant. In this context, we investigate the importance for ICT firms in Austria of variety inknowledge sourcing for their innovativeness and the relevance of geography in this respect. Theresults show that more innovative firms tend to exploit a larger variety of regional and interna-tional sources. We also find that R&D co-operations and in-house knowledge capabilities arehighly important, while firm location only shows a weak association with their innovativeness.
