ABSTRACT

Sustainability and environmental protection have become major strategic issues for companies worldwide. Green knowledge management (GKM) is considered a strategic element that enables companies to collect, share, and apply green information to meet stakeholder requirements and promote sustainability. Similarly, green innovation (GI) is recognized as a key driver of improved environmental performance. While most studies have examined these concepts separately, this study aims to investigate the relationships between GKM, GI, and green performance (GP) within a unified analytical framework. Specifically, this study examines the direct and indirect relationships between GKM, GI, and GP, highlighting the mediating role of green innovation. To achieve the study objectives, a quantitative approach was adopted. Data were collected using a survey questionnaire administered to manufacturing companies in Tunisia. The data were analyzed using a structural equation model based on the PLS approach. The empirical results indicate that GKM has a positive and significant effect on both GI and GP. Furthermore, GI has a positive and significant effect on GP. Mediation analysis reveals that GI plays a significant mediating role in the relationship between GKM and GP. This study contributes to the existing literature by proposing a conceptual model that examines the relationship between GKM, GI, and GP in the context of developing countries. Unlike previous research, which has focused primarily on developed countries, this study provides insights into how GKM practices can influence green innovation and green performance in the context of an emerging country with its own cultural and institutional framework. From a managerial perspective, the results suggest that managers could consider GKM as a strategic investment capable of stimulating green innovation and enhancing the sustainable performance of their organizations.
