Item GIS BASED MODEL OF QUOTAS REGULATION AND ITS IMPACT ON THE EXTRACTION OF ECOSYSTEMS’ NATURAL RESOURCES AND SOCIAL WELFARE(2018) Kobets, V.; Bystriantseva, A. N.; Shakhman, I. A.; Кобець, В. М.; Бистрянцева, А. М.; Шахман, І. О.Research goals and objectives: to study ecosystem using GIS based technology to develop valid recommendations forsand extraction from water body. Object of research: ecosystem with natural resources. Subject of research: GIS Based Model of Quotas Regulation and its Impact on the Extraction of Ecosystems’ Natural Resources and Social Welfare. Research methods: optimization methods, GIS methods, differential-equations method, marginal benefit-cost analysis. Results of the research: An example of mathematical model for determining of ecological equilibrium during sand extracting in the ecosystem is developed using Google Maps. The influence of economic activity due to sand extraction on fish fauna is described. The GIS based ecological-economic model is developed on the logistic model basis for establishing regional quotas for extraction of natural resources during economic activity in the South of Ukraine. Regulatory economic mechanism of natural environment is proposed. It implies such quota for sand extraction from water body, which does not lead to deterioration of the quality of the nature environment and stimulate of social welfare’s increasing.Item Impact of the Environmental Externalities and Technological Progress on the Stability of Economic System Development on the Example of the Ingulets River Basin(2020) Kobets, V.; Shakhman, І. О.; Bystriantseva, A.; Кобець, В. М.; Шахман, І. О.; Бистрянцева, А. М.Our study demonstrates the introduction of a market-based mechanism for environmental management in conditions of a shortage of natural (water) resources. The purpose of this paper is to investigate impact of the environmental externalities and technological progress on the stability of economic system development. We considered model of upstream and downstream firms with production negative externality, suppose producer pollutant and farm enterprise along Ingulets river using experimental data and OLS method. The results of the study and practical recommendations will allow participants of the technological process to respond quickly on changes in the state of the environment and make effective decisions aimed at ensuring the stability of the economic system and environmental safety. We found that enterprise’s rate of technological development inspired by IT implementation has to be 0.28 times more than technological development of pollutant to save stability of farm enterprise’s output.
