Impact of Green Human Resource Management and Green Supply Chain Management Practices on Sustainable Organizational Performance- A Case of China-Laos Railway

This study explores the synergistic effects of Green Human Resource Management (GHRM) and Green Supply Chain Management (GSCM) on the sustainability performance of large-scale infrastructure projects, with particular emphasis on the mediating role of Environmental and Social Responsibility Perception (ESRP). Through an empirical analysis of the "China-Laos Railway" (CLR), we examine how these organizational mechanisms contribute to environmental, social, and economic sustainability outcomes. Data were collected from 211 professionals at China's Ministry of Transport and Laos' Ministry of Public Works and Transport using a validated 7-point Likert scale questionnaire. Using Structural Equation Modeling (SEM), our findings reveal three critical insights: (1) Both GHRM and GSCM demonstrate significant positive correlations with CLR's sustainability performance; (2) ESRP partially mediates the GHRM-sustainability relationship and the GSCMsustainability relationship; (3) GHRM shows a moderate direct effect, while GSCM exhibits the strongest direct impact on sustainability performance. This study provides actionable insights for state-owned enterprises, suggesting that institutionalizing green management practices and strategically embedding ESRP in organizational decision-making can enhance long-term project viability. These findings advance theoretical understanding of sustainability drivers in infrastructure development while offering policymakers a framework for aligning megaproject governance with Sustainable Development Goals (SDGs).
