Research on policy options to improve the controllability of strategic material supply chain

Due to differences in resource endowment around the world, domestic supply often cannot meet demand and relies on cross-border supply chains. To enhance the resilience of cross-border supply chains, it is necessary to increase independent controllability. This requires joint participation by both the government and enterprises. This paper constructed an evolutionary game model to study the path of government policy making and enterprise integration strategy selection in cross-border supply chains, and further explores the equilibrium conditions of enterprise supply chain integration behavior under government leadership. Numerical simulation analysis shows that under most parameter conditions, the government tends towards adopting an active strategy to improve supply chain controllability based on considerations of public interest and supply chain security. Enterprise’s decision-making willingness is affected by the relationship between supply chain integration costs and benefits.
