ABSTRACT

In the current economic environment, enterprise innovation has become a key driving

force for social progress and economic growth. Providing subsidies to encourage enterprise

research and development (R&D) is a widely adopted incentive mechanism by governments

globally. This article delves into the intrinsic mechanisms of how government subsidies

influence enterprise innovation and examines how differences in enterprise types and regions

affect this relationship.

Through in-depth research, we have found a widespread inverted U-shaped relationship

between government subsidies and enterprise innovation. Government subsidies can

effectively stimulate technological innovation in the initial stages, and increasing subsidy

amounts can enhance enterprise innovation output. However, beyond a certain threshold,

negative effects may emerge. Once subsidies reach a certain level, the positive stimulating

effect on enterprise innovation may diminish or even transform. Further research shows that

government financial support has unique impacts on different types and sizes of enterprises,

as well as on enterprises in different regions. Concerning government subsidies, compared to

state-owned enterprises, the innovation incentive effect is more significant for private

enterprises. Similarly, small-scale enterprises are more sensitive to government subsidies

compared to large-scale enterprises and are more keenly aware of them. Regional analysis

indicates that enterprises in the eastern region are more directly influenced positively by

government subsidies, while enterprises in the central and western regions exhibit an

inverted U-shaped relationship between innovation output and the appearance of government

subsidies. To deepen the understanding of the relationship between government subsidies

and enterprise innovation, this article employs empirical research methods and introduces the

data sources used. Finally, the article summarizes the main findings and provides targeted

recommendations to better promote enterprise innovation.

In conclusion, this article not only deepens the theoretical understanding of the

relationship between government subsidies, enterprise R&D investment, and innovation but

also offers practical guidance for governments and enterprises. By promoting effective

policy-making and enterprise management practices, this study aims to contribute to the

sustained and healthy development of the social economy.
