Sustainable procurement implementation among public sector organisations in Ghana: The role of institutional isomorphism and sustainable leadership

Abstract

Developing nations face institutional impediments in the implementation of sustainable procurement strategies. However, in the right institutional environment, these countries can overcome any hindrance and successfully implement sustainable procurement strategies to promote economic growth and environmental stewardship. Accordingly, this study examines the role of institutional isomorphism (mimetic, coercive, and normative isomorphism) and sustainable leadership in sustainable procurement among public sector organisations (PSOs) in Ghana. The hypothesised relationships wereanalysed using partial least squares structural equation modelling (PLS-SEM).The findings support the role of isomorphism and sustainable leadership in sustainable procurement implementation. Specifically,coercive and mimetic isomorphic forces influence sustainable leadership significantly and positively. Second, coercive and mimetic isomorphic factors, as well as sustainable leadership, influence sustainable procurement practices.Based on these findings, we recommend that development partners make significant contributions to the green transition by applying coercive actions,such as threats of withdrawal of financial support for government budgets and policies. In addition, the findings of the study suggest that coercive and mimetic forces can foster a culture of ethical responsibility, by influencing leaders to make decisions that contribute to environmentally and socially responsible procurement activities.
