In today’s dynamic and knowledge-driven economy, innovation has become essential for organizational survival and sustained competitive advantage. Central to this process is absorptive capacity (AC), defined as a firm’s ability to recognize, assimilate, and apply external knowledge for commercial purposes. Although AC is widely acknowledged as a key driver of innovation, empirical findings on its effect remain inconsistent, with studies reporting positive, negligible, and even negative relationships with innovation performance. These mixed results suggest that the effectiveness of absorptive capacity may depend on contextual conditions within knowledge environments.

This study addresses this gap by examining how knowledge environment characteristics—specifically richness, protection, and intensity—moderate the relationship between absorptive capacity and innovation outcomes. Knowledge richness reflects the availability and diversity of external knowledge sources, knowledge protection captures the extent of legal and institutional safeguards such as intellectual property regimes, and knowledge intensity refers to the degree of knowledge embeddedness and competitive pressure within an industry. Together, these factors shape how effectively firms can access, process, and exploit external knowledge.

Building on organizational learning and strategic management theories, the study argues that absorptive capacity does not operate in isolation but is contingent upon external environmental conditions. In knowledge-rich environments, firms are more likely to benefit from diverse information flows that enhance learning opportunities. However, high levels of knowledge protection may restrict knowledge spillovers, thereby limiting absorptive potential. Conversely, high knowledge intensity may increase competitive pressure, compelling firms to more effectively utilize available knowledge to sustain innovation performance.

By integrating these moderating variables, the study provides a more nuanced understanding of the absorptive capacity–innovation relationship and helps reconcile prior empirical inconsistencies. The findings contribute to innovation literature by emphasizing the importance of environmental contingencies in shaping firm-level capabilities and outcomes.
