Abstract. Analysis of the ecological situation in the world suggests that ensuring economic growth of any country should be based on the principles of sustainable development. The question of the relationship between the dynamics of GDP and the degree of pollution requires a detailed study. The relationship between economic growth and the amount of emissions based on statistics of Ukraine, Poland, Germany and Lithuania is shown. The amount of emissions is one of the factors influencing economic growth, so neural networks are constructed in the article that can be used to predict the amount of emissions for countries under the World Bank classification by the income level. Also, various factors that have the greatest impact on the predicted rate of CO2 are analyzed in the article. This analysis allows selecting a set of independent variables that can provide a better prediction of the studied parameters and make appropriate economic decisions in order to achieve economic growth in a sustainable development.
Economic growth is seen as an integral part and one of the most important characteristics of economic development. The problems of considering the ecological balance in the economic growth model and allocating of the total investment in primary and secondary production are analyzed. On its basis, it is possible to analyze and forecast the optimal programs of economic development using policy instruments such as investment and consumption in the context of sustainable development in the eco-economic system.
The article is dedicated to the problem of modeling dynamic ecological-economic models in the case of ecological-economic balance. The nonlinear variant of the model of economic growth considering the ecological balance is proposed and investigated. The mathematical theory of optimal control has been selected for the research of economic growth model.
The article is devoted to the study of the impact of specific macroeconomic indicators on the formation of revenues of non-governmental organizations from personal contributions of the Ukrainian population. The Revolution of Dignity and the outbreak of military actions in eastern Ukraine have led to an increase in the role of civil society in addressing social and economic problems and to a more active participation of Ukrainian population in the activities of non-governmental organizations (direct and indirect). The study of the volume and structure of the revenues of public organizations from private individuals indicated that there is a general tendency of increase concerning these revenues (both at from membership fees and the charity of individuals), but their structure has changed significantly (the share of membership fees in the structure of revenues of public organizations decreased from being 12.5% to 10.35%). At the same time, the share of charitable donations increased from 2.94% to 5.04%. Such changes are indicative of a gradual reorientation of support from the population from organizations aimed at satisfying the interests of their members only to those that are aimed at meeting needs of the general public. Having carried out the analysis, we have found that the amount of financial resources that the population directs to support public organizations of Ukraine per capita increased significantly from 4.77 UAH to 28,03 UAH. Such data substantiates the increase of public activity among Ukrainian population. The correlation and regression analysis has made it possible to research the peculiarities of impact of such factors as population size, inflation, average and minimum wages, and the number of employed on the formation of revenues of public organizations from private individuals. Accordingly, close relationships between the factors of impact and the resulting variable were discovered. It is important that such factors as inflation, and minimum and average wages are characterized by the direct relationship, while the population and the employed population are characterized by an inverse one. Note that there is multicollinearity between the factors of influence. Interdependence between specific macroeconomic indicators is a feature of the national economy. Respectively, the system of these factors in their totality influences the revenues of public organizations from private individuals. Given the constancy of relationships between factors, one should expect a further increase in the role of private individuals in the formation of the revenues of Ukrainian public organizations.
