The article is aimed at identifying meaningful patterns that define the economic development of Ukraine, visualization and characteristic of motion trajectory of the national economy in the context of approximation to the global objectives of sustainable development. The author uses the methodological instrumentarium and categorical apparatus of the non-linear dynamics for analyzing conduct in in the phase space of the national economy as a complex adaptive dynamic system. The author has selected the key markers for sustainable economic development together with the corresponding macroeconomic indicators, by which the actual dynamics of the national economy in the period of 1988-2016 could be evaluated. It has been found that its complex and polyharmonic form is caused by the non-linear nature of oscillations. The formed phase portrait of Ukrainian economy provided to reconstruct its conduct in the phase plane in form of the phase trajectories of the basic macroeconomic indicators of development. The specific for Ukrainian economic system types of equilibrium conduct have been identified: limit cycle and fixed point, as well as the bifurcation jumps with change of the mode of functioning and the overall direction of its movement. The obtained results of the study extend capabilities of the qualitative forecasting of processes of development of the Ukrainian economy.
Keywords: development, macroeconomic dynamics, dynamic system, phase trajectories, attractor, bifurcation jump
