NVESTIGATION OF GROWTH FACTORS OF KAZAKHSTAN INDUSTRIAL PRODUCTION BY PRODUCTION FUNCTIONS

Purpose – the purpose of the study is to investigate the growth factors of industrial production in Kazakhstan, by building the production functions of Cobb-Douglas, J. Tinbergen and R. Solow, to give an economic interpretation of the obtained parameters. To determine and analyze in dynamics the indicators of average and marginal efficiency, the rate of substitution of resources. Make a conclusion about the efficiency of resource use and determine the type of economic growth during the analyzed period.
Methodology – the methodological basis of the research is made up by the main provisions of the theory of production, the results of theoretical and applied research on the problems of constructing economic and mathematical models and their effective use in order to maximize profits and reduce costs. The study used mathematical methods as the most important tool to uncover quantitative relationships, to determine on this basis the degree of influence of factors on the final result of production activities, to control the production process in accordance with the obtained quantitative characteristics.
Originality/value – the constructed production functions are linearly homogeneous and show constant efficiency with an increase in the factors of industrial production, which is typical for extensive type of economic growth.
The average and marginal efficiency of the use of labor resources was significantly higher than the fixed capital, which indicates the importance of this factor for the growth of industrial production in Kazakhstan. This statement is objective in the framework of existing technologies and quality characteristics of resources.
Findings – the assessment of adequacy has shown that the Cobb-Douglas model and the J. Tinbergen model most accurately approximate the initial data. The constructed models are classical; reflect the operation of economic laws, have an objective nature, and characterize stable cause-and-effect relationships. The results obtained in the study can be used to analyze the development of industry in Kazakhstan, to predict the volume of industrial production, depending on changes in the costs of resources used.
