ECONOMIC AND MATHEMATICAL ANALYSIS OF IMPACT INVESTMENT ON EFFICIENCY OF THE ENTERPRISE
Keywords:net income, investment deposits, regression, multifactor model, multicollinearity, elasticity
Goal. Study of the impact of investment on net income through the use of multifactor regression models of enterprise of Zaporizhia.
Method. Based on econometric analysis, a methodology has been developed that allows to analyze the impact of the size of investment deposits on the net income of the enterprise, which is based on the use of multifactor regression models of economic activity of enterprises.
Results. The versatility of information on the economic activity of enterprise in Zaporizhia indicated the difficulty of analyzing the results. At the same time, the transition to a digital economy based on modern IT technologies has made it possible to re-use statistical material on economic indicators of enterprises, synthesizing economic and mathematical models of enterprises as complex objects by deeper elaboration of statistical material with justification of the results. This approach made it possible to use multifactor regression models to obtain the dependence of net income on the value of investment deposits at specific enterprise in Zaporizhia.
Scientific novelty. For the first time, multifactor regression models of economic activity of enterprises are used, taking into account multicollinearity and nonlinearity in the value of investment contributions for economic analysis of the impact of investment on net income by using the coefficient of elasticity.
Practical significance. The analysis of the results of economic and mathematical modeling of Zaporizhia enterprise, which is based on statistical material using the algorithm of studying the dependence of net income on the value of investment contribution, showed the presence of critical values of investment deposits that qualitatively change the impact on net income. It is recommended to include the developed algorithm in the practice of appropriate calculations of the effectiveness of economic activity of enterprises.
