Экономический рост и инвестиции в НИОКР: эмпирический анализ российских регионов
Investment in R&D is a major driver of economic growth. Its impact on economic growth is formed from the direct effect and spillover effect, due to which investments in a particular region affect the development of nearby regions. The paper employs real GRP and R&D capital stock as indicators of economic growth and investment in R&D. Real GRP and R&D capital stock are estimated using the perpetual inventory method. To obtain quantitative estimates, static and dynamic spatial Durbin models are applied on Rosstat panel data for 76 Russian regions in the period 2001–2021. Models are estimated via quasi-maximum likelihood. The results indicate the presence of both short-term and long-term direct impact of R&D capital on real GRP. At the same time, only several model specifications indicate the presence of a spillover effect. This result coincides with previous studies that noted weak linkages between Russian regions and insufficient efficiency of the Russian R&D sector.
