MODELING OF INTERACTION OF THE FACTORS OF DEMAND AND SUPPLY OF ECONOMIC GROWTH

Анотація

The initial essence of economic growth is to increase the potential and real gross of the national product and manifest it as an increase compared to the previous period, the value of gross domestic product per person. The Keynesian theory of economic development is based on the main postulate of J. Keynes -aggregate demand, so while the development of economic and mathematical models describe economic growth, the key parameter remains the growth of aggregate demand. The offer and the factors that affect the supply and demand remain outside the models. The article schematically shows the relationship between demand factors, supply factors and economic growth. Supply factors have a direct impact on economic growth, but quantitatively depend on demand factors, mainly on investment. With the help of the apparatus of differential calculus the model of distribution of innovations as the basic condition of intensification of factors of the offer was created. Based on it, the process of innovation of the factors of supply of economic growth has been modeled. At the same time, the innovation model based on the innovation lag has been created. Taking into account formalized schemes and created models, and applying integral calculus, three-factor and one-factor production functions with the corresponding equations of integral figure and curve have been derived. The growth of fixed capital accumulation ensures its share in GDP of less than 15%. This is much less than the average world's minimum of 22-24%. It means, that these funds are not enough to reproduce the demolished production facilities and social facilities. Accordingly, there are almost no financial resources for basic innovations and technological renewal of the economy. The first investment steps should be taken by the state in conditions of complete deficit of investment resources in the real, research and socio-economic sectors of the national economy and with limited opportunities for public investment with the simultaneous presence of a high degree of risk Therefore, effective methods of debt management in line with sustainable economic growth will allow businesses not only to intensify but also to qualitatively expand their activities with subsequent positive consequences, including solving existing socio-economic and environmental problems and strengthening national security.
