The research “Empirical Methodology of Modern Monopolisation Process Assessment: an Extended Commentary” is an elaborated continuation of a study, previously conducted by the Authors (Skoruks, Senfelde, 2015), which capitalises on the relevant retrospective findings and delivers a multi–perspective in–depth description of the nature, the occurrence sources, the progression algorithm and the internal conjuncture specifics of the contemporary monopolisation process, while providing an example of market trend-detecting econometrical method implementation within a unified framework of competition analysis. The main scope of the research is devoted to developing and further enhancing the existing monopolistic trend detecting practices via quantitative analysis and multi-perspective examination of monopolisation effects, observed in modern globalized markets. The current research employs a system of monopolisation process progression describing quantitative indicators, based on authentic calculations, conducted within the framework of competition structure analysis in several industries over a five sequential year period, perceived through the prism of market power distribution between the involved supply-side market actors.
