Sustainable procurement adoption and sustainable performance the role of isomorphic pressures

Abstract

The study examined the relationship between isomorphic pressures, sustainable procurement adoption and performance of public entities in Ghana. The study used an explanatory research design and a quantitative research approach. Relying on institutional and stakeholder theories, data from 307 public entities were gathered using structured questionnaires and analysed with frequencies, means, standard deviation, partial least squares structural equation modelling (PLS-SEM). Simple random sampling technique was used to determine the sample size. The study proved that isomorphic (coercive, normative and mimetic) pressures influenced sustainable public procurement adoption. Similarly, sustainable procurement adoption mediated the relationship between isomorphic pressures and sustainable performance. The study recommended that institutional regulatory bodies like the Public Procurement Authority of Ghana should spearhead the sustainable operations of public procurement. The findings of the study proved that isomorphic pressures (normative, coercive and mimetic pressures) have a positive and significant effect on sustainable procurement adoption in Ghana. All the three hypotheses were supported. The second objective sought to examine the effect of sustainable procurement adoption on sustainable performance in Ghana. One hypothesis was formulated and tested at the end of the analysis, proving that sustainable public procurement adoption significantly influences sustainable performance.The third objective assessed the mediating role of sustainable procurement adoption in the relationship between isomorphic pressures (coercive, normative, mimetic) and sustainable performance.
