Enhancing work safety behaviors among Small and Medium-Sized Manufacturing Suppliers (SMMs) is crucial for establishing a more secure and efficient supply chain. Since the foundation of safety lies in positive prevention, it is crucial that SMMs adopt proactive and pro-social work safety behaviors that transcend mere compliance with standard regulations. Present-day diversified supply chain safety management apply varying degrees of pressures on SMMs. The effectiveness of such pressures, as well as their potential to spawn advanced safety behaviors in SMMs, is a matter of investigation. This research investigates the impact of Supply Chain Safety Management Pressure(SCSMP) on the SMMs' Work Safety Behaviors(WSB). A theoretical framework is constructed, grounded in institutional theory and theory of planned behavior, which earmarks three distinct dimensions of SCSMP: Coercive Pressure(CP), Mimetic Pressure(MP), and Normative Pressure(NP). The survey of 265 SMMs facilitated an assessment of the SMMs' Willingness for Responses(WR), which includes their Willingness for Adaptive Responses(WAR) and Willingness for Co-creative Responses(WCR). Subsequently, the resulting WSB entail Safety Compliance Behavior(SCB), Proactive Safety Behavior(PSB), and Pro-social Safety Behavior(PsSB). Among these, SCB is categorized as a basic safety behavior, while PSB and PsSB which emphasize voluntary, active, and cooperative actions, are classified as advanced safety behaviors. Our research findings underscore the substantial influence of the SCSMP in shaping WSB. WR serves as a critical intermediary, connecting external pressures with internal organizational practices. In particular, WCR is instrumental in the formation of advanced safety behavior. The theoretical contribution of this research is manifested in its enhancement of our comprehension regarding the determinants of WSB among SMMs. Furthermore, it addresses the literature gap in elucidating the effectiveness of supply chain safety management and the mechanisms behind the formation of WSB. The practical significance lies in elevating the overall safety standards throughout the supply chain and minimizing safety-related hazards among SMMs.
