The purpose of this article is to investigate the ways in which innovation and knowledge sharing have been studied together in the academic literature. The method employed in this study was a systematic review that covered publications on knowledge sharing and innovation from 1973, when the first article relating the two topics was published, to 2017. The survey was based on 7,991 articles from the Scopus and ISI Web of Science databases using VantagePoint 11.0 software. Four periods were identified in the relationship between innovation and knowledge sharing: embryonic, emergent, growth young, and growth highest. The relationship between knowledge sharing and innovation continues to grow based on the number of papers published on the topic by year. This is the first systematic review of the relationship between knowledge sharing and innovation.
