Based on a generalization and analysis of the methods and tools for assessing the impact of import substitution on the economy used by domestic and foreign authors in their studies, scientific-methodological approaches to such an impact were identified. In model approach, an author’s assessment methodology has been developed. At the first stage using an expanded system of import substitution effectiveness indicators, which grouped by sectors of the economy, a composite indicator of the effectiveness is formed by means of principal components method. At the second stage the dependence of economic growth on a composite indicator of import substitution effectiveness is formed by means of correlation and regression analysis.
