Disaster Response Mechanisms for Key Technology Innovation in China’s Emergency Industry Under the New National System

The emergency industry refers to a comprehensive industrial system of products, technologies, and services aimed at preventing, responding to, and mitigating emergencies. The emergency industry is primarily oriented toward disaster prevention and mitigation, providing direct support to enhance societal resilience. Given the frequent occurrence of natural disasters and the strategic layout of global emergency technologies, it is of great practical significance to study how the science and technology systems of disaster-prone countries respond. Based on the theories of disaster economics and innovation geography, this paper constructs a mediation effect model to investigate how China improves the key technological capabilities of its emergency industry through three response pathways—demand stimulation, technological advancement, and educational enhancement—following natural disasters. The stepwise testing approach, which integrates the mediation effect model with the spatial Durbin model, consists of three stages. The first stage tests the total effect model to assess how disasters impact local key technologies and their spatial spillover on adjacent regions. The second stage examines the direct influence of disasters on the three pathways and their spatial spillover using the mediator equation. The third stage uses the outcome equation with the mediator to evaluate how the pathways affect local key technologies and neighboring regions after controlling for disaster impacts. We offer both theoretical insights and empirical evidence to support specialized research on technological diffusion induced by disasters. The result shows that although the direct negative impact of disasters is inevitable, the institutional advantages of China’s emergency rescue and innovative collaborative efforts have played a significant role in promoting key technologies. Under the new national system, China is progressively establishing a spatial framework wherein emergency products are allocated across regions, key technologies are synergistically integrated, and the development of emergency-related disciplines is promoted through regional collaboration in response to the frequent occurrence of natural disasters. This demonstrates that the advancement of key technologies in China’s emergency industry is significantly supported by inter-regional cooperation and linkage mechanisms.
