Abstract
SMEs are critical to Nigeria’s economy, yet their innovation capability is hindered by institutional and resource constraints. Drawing on the knowledge‑based view (KBV), this study investigates how Nigerian Tech SMEs build and sustain innovation capability through engagement with local, regional, and international knowledge networks. Using an interpretivist qualitative design, data is collected from founders and senior managers of Tech SMEs through semi‑structured interviews. Preliminary findings reveal a layered network strategy characterised by a strong dependence on local actors for tacit, context‑specific knowledge, coupled with highly selective international ties for advanced technologies, legitimacy, and market access. However, regional networks remain thin due to regulatory fragmentation and capability asymmetries. This study also identifies four micro‑processes, boundary‑resource investments, AI‑enabled codification, structured feedback loops, and reputational brokerage, through which SMEs absorb and internalise external knowledge. The study extends the KBV by showing that external knowledge search yields location‑contingent returns shaped by the institutional environment. Policy implications emphasise the need for regulatory harmonisation, improved infrastructure, and support mechanisms to strengthen SMEs' innovation capacity.
