Abstract:Industrial clusters are important carriers for creating regional wealth, cultivating competitive advantages, and nurturing and growing new enterprises and technologies. The technological innovation of enterprises in industrial clusters is crucial, as it can enhance the overall strength of the cluster and promote regional economic development. Selecting core and non core enterprises with competitive relationships in nuclear industrial clusters as the research objects, by constructing a Stenberg model and combining fully rational dynamic game theory with system simulation, the strategy selection problem of competitive enterprises in industrial clusters when conducting technological innovation games is analyzed. The results indicate that the technological innovation of competitive core enterprises and non core enterprises in industrial clusters has interactivity and traction; The strategic choice of enterprise technological innovation is the result of the comprehensive effect of internal and external factors such as market size, innovation investment, and innovation capability; The relative comparative advantage of technological innovation capability is a key factor determining the specific innovation strategy selection and final market position of an enterprise.
