The research “The Empirical Methodology of Modern Monopolization Process Assessment as a Sustainable Consumption Ensurance Tool” provides a multi – perspective in – depth description of the nature, the occurrence sources, the development procedure and the internal conjuncture specifics of the present day monopolization process as well as providing an example of modern econometrical method application within a unified framework of market competition analysis for the purpose of conducting a quantitative competition evaluation on an industry – level, resulting in applicable outcomes, suited for practical use in both private and public sectors. The main question of the aforementioned research is the definition and quantitative analysis of monopolization effects in modern day globalized markets, while constructing an empirical model of the econometric analysis, based on the use of international historical experience of monopoly formations standings, with the goal of introducing a further development scheme for the use of both econometrical and statistical instruments in line with the forecasting and business research needs of enterprises and regulatory functions of the public sector. The current research uses a vast variety of monopolization evaluation ratios and their econometrical updates on companies that are involved in the study procedure in order to detect and scalar measure their market monopolizing potential, based on the implemented acquired market positions, turnover shares and competition policies.
