Abstract
The aim of this research was to demonstrate a cause–effect relationship in terms of the mode of inter-organizational relationships and the results of research and development through open innovation for the pharmaceutical industry. In various previous studies on the development of new drugs, conclusions regarding the effects of open innovation have not necessarily been coherent. This research used an empirical study to identify the most desirable inter-organizational relationships and management styles for the pharmaceutical industry. In terms of research methodology, a questionnaire was conducted. In addition, a patent database of drug development was analysed using the technique of social network analysis. In conclusion, the depth and breadth of inter-organizational relationships could have a serious influence on the success or failure of an open innovation. Also, suitable organization management according to the difference in industry segment or product characteristics became clear.
