Abstract: Social business as a special kind of entrepreneurial activity started developing in Russia relatively recently during a short time period since the beginning of the 21st century. Nevertheless, society and the government lay high hopes for its contribution to the strategy of the country. Meanwhile, in foreign countries with market economy this business line is theoretically justified and has been represented by an extensive practical activity, however in a number of publications of both foreign and domestic authors the categories of "the social business" and ‘the social responsibility of business" are considered as synonyms. At the same time, the historical process of contemporary Russian entrepreneur formation demonstrates that "the social responsibility of business" and "the social entrepreneurship" are phenomena of certain quality and cultural level of the entrepreneur corps. Formation of these categories needs substantial support both by the state and society. This circumstance makes the concerned issues quite important and determines the research feasibility of the current study. The study presents the comparative analysis of ideas concerning the ontological concept of the terms of "corporate social responsibility", "social entrepreneurship" and "culture of entrepreneurship", as well as the formation stages of the contemporary social entrepreneurship in Russia on the example of the Far Eastern constituent entities which are the objects of intensive development at the present stage while implementing country’s strategic tasks in the process of Russia’s integration with the countries of Asia-Pacific Region (APR).
