Abstract
The aim of this study is to demonstrate the capabilities of the Jamovi software in analyzing complex economic models, using the case of examining the impact of various factors on enterprise innovation activity. Structural Equation Modeling (SEM) was employed to identify both direct and mediated relationships among economic and digital infrastructure, factors related to research and development (R&D), and innovation activity. The analysis results confirmed the positive impact of economic infrastructure on the level of R&D and the innovation activity of enterprises, as well as the mediating role of R&D factors in transmitting the effects of infrastructure. Meanwhile, the influence of digital infrastructure was found to be weak, highlighting the need for further development of digital technologies and their integration into economic activities. The findings and methodology of the study can be utilized to enhance the competitiveness of enterprises and to develop effective measures for state support of innovation activities in various regions.
