Abstract: The article examines the impact of such factors as the average monthly salary of employees, investment in fixed assets, tax burden, cost value for research and development, and workforce productivity. For building the model, the author applies statistical data on socioeconomic development indicators of 32 constituent entities of the Russian Federation for 2017. Tax burden lowers the workforce productivity; therefore, the use of tax incentives and preferences contributes to the achievement of the goals of economic growth. The research is based in the general scientific methods of analysis and synthesis, as well as econometric analysis. The article is dedicated to the creation of correlation-regression model of impact assessment. The conclusion is drawn that three out of four determinants indicate a significant positive correlation with workforce productivity. The effective tax incentive mechanism may become a catalyst for the economic development and contributes to securing employment.
