The influence of lean manufacturing and green supply chain management on firm performance: the mediating role of supply chain resilience

This study examines the relationships between lean manufacturing, green supply chain management (GSCM), supply chain resilience (SCR), and firm performance in Thai manufacturing companies. Using data from 322 employees across various industries, the research employs co-variance-based structural equation modelling to test a series of hypotheses. The findings reveal that lean manufacturing has significant positive effects on both GSCM practices and firm performance. GSCM practices demonstrate a strong positive impact on SCR. However, contrary to expectations, the study finds no significant direct relationship between GSCM practices and firm performance, nor between SCR and firm performance. The hypothesized mediating roles of GSCM practices and SCR in the relationship between lean manufacturing and firm performance are not supported. These results suggest that while lean manufacturing and GSCM practices contribute to improved operational efficiency and environmental sustainability, their translation into enhanced financial performance may be more complex than previously thought. The study contributes to existing literature by providing empirical evidence from the Thai manufacturing context and highlights the need for further research into how operational improvements in lean and green practices can be converted into tangible financial outcomes.

In an increasingly competitive global automotive landscape, the strategic integration of Total Quality Management (TQM) and Lean Practices (LP) has emerged as a crucial determinant of operational excellence and sustained organizational performance. Grounded in empirical evidence from the Thai automotive sector, this study explores the intricate synergies between TQM with Malcom Baldrige National Quality Award (MBNQA) dimensions, lean implementation, and firm performance. This study employs the quantitative research method, where the measurement scales for each construct were adopted from the literature and reviewed by academics. Data were collected from 854 manufac-turing firms in Thailand through a mail survey method. This study applied a two-step structural equa-tion modeling (SEM) process. The findings reveal a robust direct effect of TQM (leadership, strategy planning, customer and workforce focus) on firm performance, underscoring its pivotal role. Notably, TQM also exhibited a substantial indirect effect on business performance, mediated sequentially through lean practices including continuous flow, 5S, and total preventive maintenance. Lean practices similarly demonstrated significant direct and indirect effects on firm performance. Collectively, the combined effects of MBNQA and lean practices on firm performance was also observed, substantiat-ing their complementary contributions. These findings hold significant implications, both from an ac-ademic and a practical standpoint. From a theoretical perspective, this research enriches the discourse by providing empirical insights into the mediating roles of lean practices, elucidating the paths through which TQM's performance-enhancing effects can be transmitted. Concurrently, the magnitude of the impact these practices have on firm performance underscores their practical relevance, and insights derived from this study could play a key role in guiding automotive firms and suppliers to align critical components to drive performance excellence.
