Research on evaluation of implementation effect of science and technology innovation policy

• Science and technology innovation policy plays a huge role in promoting China's science and technology development. • China's scientific and technological innovation policy has achieved remarkable results in promoting the improvement of scientific and technological innovation ability. • Policies have achieved outstanding results in optimizing the innovation environment and improving regulations and industry management capabilities. • Science and technology innovation capability is the core position. • The level of financial services plays a key role in accelerating the process of scientific and technological innovation. Science and technology innovation policy plays a huge role in promoting China's science and technology development. The manuscript evaluation aimed at 861 policy texts of China's science and technology innovation policies from 2013 to 2023. Manuscript evaluation aimed at 861 policy texts of China's science and technology innovation policies from 2013 to 2023, a high-frequency node network was constructed through text analysis, and Gephi was used for modular classification. Based on this, the influencing factors that comprehensively cover the key links of science and technology policy are selected to construct the initial multi-level policy implementation effect evaluation index system. Then the index system is deeply optimized by factor analysis to obtain a scientific and efficient evaluation index system. Finally, the entropy method was combined to find that China's science and technology innovation policy showed an overall fluctuating upward trend during the study period, especially during the epidemic period, showing strong resilience. Based on this, it was proposed that China must strengthen the efficiency of science and technology system management, increase the support of financial services for science and technology innovation, and improve policy adaptability and other countermeasures and suggestions in response to the rapid changes in domestic and foreign markets.
