Corporate social responsibility and green supply chain efficiency: conditioning effects based on CEO narcissism

Accelerating the construction of the green supply chain system and improving the efficiency of the green supply chain is the key to promoting the high-quality development of enterprises. In view of this, based on stakeholder theory, higher order theory and expectancy theory, this study focuses on the impact of corporate social responsibility (CSR) on corporate green supply chain efficiency (GSCE) and the moderating role of chief executive officer (CEO) narcissism. A regression analysis of the observed sample reveals that CSR significantly enhances GSCE. Further decomposing CSR into internal CSR and external CSR to reveal the impact of different types of CSR on GSCE, we find that internal CSR fulfillment has a significant positive impact on GSCE, and this relationship is strengthened when CEOs are narcissistic. Furthermore, external CSR has a significant negative impact on GSCE, and this relationship is also strengthened by CEO narcissism. The main contribution of this paper is to study the relationship between CSR and green supply chain efficiency, decompose CSR into internal and external CSR, enrich the research on the intrinsic mechanism of value creation of CSR. It also enriches the research in the context of CSR from the perspective of CEO personality traits, providing new ideas and suggestions for manager selection and corporate greening governance in practice.
