Corporate governance and sustainability: a review of the existing literature

Over the last 2 decades, the literature on corporate governance and sustainability has increased substantially. In this study, we analyze 468 research studies published between 1999 and 2019 by employing three clustering analysis visualization techniques, namely keyword network clustering, co-citation network clustering, and overlay visualization. In addition, we provide a brief review of each cluster. We find that the number of published items that fall under our search criteria has grown over the years, having surged at various times including 2014. We identified three main thematic clusters, which we have called (1) corporate social responsibility and reporting, (2) corporate governance strategies, and (3) board composition. The weighted average years that major keywords appear in the literature published over the last 2 decades fall into a period of 4 years between 2014 and 2017. This is due to the massive increase in the number of publications on corporate governance and sustainability in recent years. By means of chronological analysis, we observe a transition from more abstract concepts—such as ‘society,’ ‘ethics,’ and ‘responsibility’—to more tangible and actionable terms such as ‘female director,’ ‘board size,’ and ‘independent director.’ Our review suggests that corporate governance and sustainability literature is evolving from quite a conceptual approach to rather more strategic and practical studies, while its theoretical roots can be traced back to a number of foundational studies in stakeholder theory, agency theory and socio-political theories of voluntary disclosure.
