Abstract: Study topic : Regional asymmetry and structural constraints in Russian Federation regions and their impact on the digital environment, research staff potential, and innovation output. The work’s goal : To empirically evaluate how the digital environment and research staff capabilities influence the conversion of innovation spending into innovationresults, while also examining if digitalization’s effect on regional innovation is non-linear. The methodology is rooted in the principle of complementary assets. The empirical basis is Rosstat data for 75 constituent entities of the Russian Federation for 2014–2024. The analysis involves a linear panel model with fixed regional and year dummy effects, alongside a random effects model for comparative analysis. To justify model selection and diagnose multicollinearity and cross- sectional dependence, the Breusch–Pagan, Hausman, VIF, and Pesaran tests are utilized. The results indicate that the impact of linear moderation from the digital environment and research staff potential on innovation expenditure — output is not statistically significant in any of the analyzed scenarios. The authors see this as proof that the linear complementary assets concept has restricted use in Russia’s regions. The study confirms a U-shaped link between the digital environment and innovation output: The digital environment index’s linear and quadratic terms show positive and significant coefficients, indicating that returns grow after a key level of digital maturity is attained. The consistent negative impact of fixed capital investment is understood as innovation activity being displaced by investment, especially in resource- and capital- intensive sectors. The positive impact of the gross regional product (GRP) per capita confirms the role of economic development, but does not compensate for structural limitations. The scientific contribution of this study is the simultaneous testing of the moderating and nonlinear effects of the digital environment and research human resources on panel data from Russian regions over an extended period, including the interpretation of statistically insignificant moderating results as meaningful evidence of the contextual dependence of complementary assets rather than as a methodological artifact. It also interprets non-significant moderation findings as substantive proof of complementary assets’ context dependency, not as a methodological flaw. The findings lay the groundwork for continued investigation into digitalization’s threshold effects, spatial knowledge spillovers, and how effects vary across different regional innovation systems. The study’s practical value lies in supporting a varied regional innovation strategy. For areas with low digital development, the focus should be on reaching a basic infrastructure level. Conversely, regions with strong resource specialization need to shift investments towards technological renewal, R&D, and high-tech services.
