Abstract:The regional technology innovation ability evaluation system was constructed from three aspects of technology input, technology output, technology development environment and three aspects of industry, university and research institute. The factor analysis method was used to extract three common factors, namely the innovation ability of enterprises, innovation ability of universities and research institutes and the impact of education environment, to evaluate and analyze the technology innovation ability of Jiangsu Province. The results show that the innovation ability of enterprises has the greatest influence on the overall technological innovation ability of the region, followed by the innovation ability of universities and research institutes, and the influence of education environment is limited. At the same time, it is found that the innovation ability of enterprises in Jiangsu province is at a high level, but the technological innovation ability of schools and R&D institutions is still lacking.
