Research on the Influence Mechanism of Digital Technology on the Structural Stability of Regional Innovation System Based on SFA Model

In the context of global digitization, digital technology has become an important choice for national strategic development to strengthen the structural stability of regional innovation system. This paper selects the output efficiency of the innovation system structure as the index of its stability. Based on the SFA model, this paper constructs the structural stability equation of innovation system, and finally uses the multiple regression method to explore the impact of digital technology on the structure of regional innovation system. The results show that the innovation system is a complex and comprehensive system, and its structural stability is supported by all subjects, systems and elements in the system. With the deepening of digital technology, it will positively promote the structural stability of regional innovation system, and the degree of promotion presents an inverted U-shape. And the promotion of digital technology to each subsystem in the system is heterogeneous, which is embodied in that scientific research institutes are greater than enterprises and greater than universities. Therefore, the suggestions are as follows: 1. Accelerate the development of digital technology. 2. Improve the relevant policies of digital technology and innovation system. 3. Expand the promotion of digital technology.
