Further, the results showed that intellectual capital has direct and significant influences on organizational performance. Finally, the results showed that intellectual capital has mediating effects on the relationships between organizational capabilities (market-sensing, audience knowledge, relational, and innovation) and organizational performance at Shiraz Payam Noor University.
