How firms accumulate knowledge to innovate - an empirical study of Vietnamese firms

Purpose Organizational innovations are closely associated with organizational knowledge, and thus a firm builds its knowledge base to enhance its innovative performance. However, insights into this process are still limited, especially in the context of firms in developing countries. Building on the dynamic managerial capabilities literature and open innovation paradigm, this paper attempts to fill this gap by developing and empirically testing a model that investigates how firms in developing countries accumulate knowledge to innovate. Design/methodology/approach A model of a firm's knowledge accumulation and innovation is proposed in which it specifies relationships among absorptive capacity, knowledge breadth, research and development (R&D), knowledge depth, exploratory innovation and exploitative innovation, and then it is empirically tested by using the structural equation modeling (SEM) technique based on the surveyed data of Vietnamese firms. Findings The results indicate that absorptive capacity positively influences both knowledge breadth and knowledge depth, knowledge breadth positively influences R&D, R&D positively influences exploratory innovation and knowledge depth, and knowledge depth positively influences exploratory and exploitative innovation. Practical implications The study proposes an "acquire and develop" open innovation model for firms in developing countries in which firms acquire external technologies and then develop R&D (develop and design) capability to adapt acquired technologies to their local conditions to create new organizational-specific capabilities and exploratory innovation. Originality/value This study argues that external knowledge acquisition is beneficial to innovative performance of firms in developing countries via renewing their knowledge base. Furthermore, the study provides the unique evidence that novel external knowledge acquisition and internal R&D are fit to each other in the fit-as-mediation form in which novel external knowledge acquisition is mediated by R&D to positively influence exploratory innovation.
