There is increasing research on the knowledge networks as sources to acquire and access knowledge. While this literature mainly has focused on the contribution of the network structure characteristics, existing reviews show the current literature has produced seemingly contradictory results and a growing body of research highlights the need for contingency approaches. Based on a thorough literature review, this research focused on partner diversity as one of the contingencies; this has also been considered as a measure for the knowledge exploration process. Hence two hypotheses were formulated and tested by studying the patent co-authorship networks of biotechnology firms in Victoria, Australia. Using social network analysis and moderated multiple regressions, our research positively confirmed the relationship between knowledge processes and network structure. Also based on the interaction analysis, two interesting inter-relations are discussed. Finally the implications of the findings and the potential to contribute to understanding prior contradictory results are discussed.
