Outline
An evolutionary game model was constructed based on evolutionary game theory and complex network theory to analyze the two-stage diffusion mechanism of industrial general purpose technologies (GPTs): secondary development among enterprise groups and complementary product purchases among consumer groups. The model incorporated the heterogeneity and complex network topology of diffusion groups and included three elements: game subjects, evolution rules, and network structures. The diffusion paths on the supply side and demand side were depicted, and the optimal government incentive strategies in the two diffusion stages were explored. The results show that the incentive effect of government subsidies on the diffusion of industrial GPTs follows an inverted U-shaped trend. Both excessive and insufficient subsidies reduce resource allocation efficiency. Peripheral enterprises are more concerned than core enterprises with the technical maturity after secondary development and the intensity of government subsidies. Consumer diffusion follows price-based mechanisms. Lowering the price of complementary products and improving their technical maturity significantly promote market penetration. In addition, the stability of GPT diffusion is significantly influenced by the network structure of diffusion groups. Reducing innovation costs or product prices helps enhance the stability of industrial GPT diffusion. These findings reveal the multi-agent coordination mechanism and the boundary effect of policy incentives in the diffusion of industrial GPTs and provide theoretical support for optimizing policy tools and improving diffusion efficiency.
