a monolithic model for identifying innovation drivers among knowledge-based organizations.

The need for product innovation is necessary to compete in the domestic and global markets. On the other hand, the importance of new product development, as one of the revenues generating areas for companies and the country as well as identification of the necessary factors and contexts for creating innovation capabilities has become a strategic requirement in the knowledge-based industries. In this article, we strived to identify the factors affecting the creation and strengthening of product innovation capabilities, while the relationship model between these factors is evaluated and proposed, which are the drivers of product innovation. For this purpose, we first investigated meta-analysis model among 52 effective international researches in the field of product innovation, among which 15 researches were selected. Then, the identified drivers were classified into six factors. The status of research variables was assessed through distribution of a carefully designed questionnaire among 250 people of the knowledge-based companies include employees, senior managers and middle managers. Their responses were analysed using structural equation modeling, confirmatory factor analysis and regression correlation test to prove the proposed research model. The Findings showed that three components of innovation culture, intra-organizational communication and knowledge management have an effect on product innovation in knowledge-based organizations, while three components of external communication, organizational structure, and intellectual capital have no effect.
