This chapter investigates the competitiveness of entrepreneurial firms from a network perspective. Firm competitiveness can not sufficiently be explained by extracting a firm from its context as if it were an island. Firm networks, on both an individual (ego-networks) and global (regional or full networks) level, contribute to a better understanding of firm competitiveness. The chapter explores how network advantage is generated on a regional level and how differential competitiveness is a function of public and private benefits accruing to firms embedded in regional networks. As a consequence, it is proposed that competitiveness research benefits from adopting a relational view. This extends the sources of competitiveness for a firm by studying influences of aggregated constructs (regions, nations) on a firm’s competitiveness, by analyzing the effects of firm competitiveness for aggregated constructs and by adopting a contingency view for network effects that includes space and time.
