A plurality of subjects of ownership characterizes the Russian economy. The transformation processes that began in 1991 continue to the present day. Until now, the question of the comparative effectiveness of various ownership forms remains open. Based on the analysis of trends in public and private property in Russia in 1992-2018, the article examines the correspondence of these processes to important systemic properties: cyclicity, cumulativeness, nonlinearity, and evolutionary character. Special attention is paid to such indicators of transformation processes as investments in fixed assets under various ownership forms. The conclusion is made about the low efficiency of the existing ownership structure in ensuring the Russian economy’s sustainable development. A hypothesis is put forward about the need to further develop forms and relations of ownership based on the development of alternative forms of ownership, including shared ownership.
