Item Environmental, energy and economic security: Assessment and interaction(The International Conference on Innovation, Modern Applied Science & Environmental Studies, 2021) Самусевич, Ярина Валентинівна; Самусевич, Ярина Валентиновна; Samusevych, Yaryna Valentynivna; Височина, Аліна Володимирівна; Высочина, Алина Владимировна; Vysochyna, Alina Volodymyrivna; Васильєва, Тетяна Анатоліївна; Васильева, Татьяна Анатольевна; Vasylieva, Tetiana Anatoliivna; Лєонов, Сергій Вячеславович; Леонов, Сергей Вячеславович; Lieonov, Serhii Viacheslavovych; Похилько, Світлана Василівна; Похилько, Светлана Васильевна; Pokhylko, Svitlana VasylivnaThe paper is devoted to the investigation of environmental, energy and economic security by multivariate analysis methods. A set of indicators selected for research conducting includes 9 parameters for each security type. Study sample is formed by data for 6 Eastern European countries (Ukraine, Moldova, Poland, Romania, Hungary and Slovak Republic) for the period 2000–2019. Empirical study was conducted by factor analysis, which allowed identifying the main components of environmental, energy and economic security. Comparison of the results obtained for the studied countries showed differentiation of individual profiles of such types of security. Investigation of integral vectors of environmental, energy and economic security showed the highest level of interaction between energy and environmental security and the lowest one between energy and economic security.Item Cluster analysis of development of alternative finance models depending on the regional affiliation of countries(Business and Economic Horizons, 2019) Рубанов, Павло Миколайович; Рубанов, Павел Николаевич; Rubanov, Pavlo Mykolaiovych; Васильєва, Тетяна Анатоліївна; Васильева, Татьяна Анатольевна; Vasylieva, Tetiana Anatoliivna; Лєонов, Сергій Вячеславович; Леонов, Сергей Вячеславович; Lieonov, Serhii Viacheslavovych; Похилько, Світлана Василівна; Похилько, Светлана Васильевна; Pokhylko, Svitlana VasylivnaThe article examines the hypothesis about the existence of regional peculiarities in the development of alternative financing models (such as p2p consumer lending, p2p business lending, p2p real estate lending, balance sheet business lending, balance sheet consumer lending, equity-based crowdfunding, reward-based crowdfunding, real estate crowdfunding, profit sharing crowdfunding, donation-based crowdfunding, invoice trading, debt-based securities). According to an alternative hypothesis, due to the high integration of international financial markets, there are no regional peculiarities of the development of alternative financing models. The cluster analysis tools allow verifying these hypotheses. The cluster analysis methods used, such as tree clustering, k-means clustering, and two-way joining, demonstrate the lack of links between the country's regional affiliation and the degree of development of certain types of alternative financing in it. The key factors affecting the formation of clusters are volumes of peer-to-peer consumer lending and business lending, as well as the volume of invoice trading. According to the results of the research, the authors conclude that it is necessary to find other factors, apart from the regional features, which influence the ratio in the development of certain types of alternative financing in different countries.
