Abstract.  Authors examine economic effects of regional integration in the emerging markets, impact of globalization on economic integration and existing models of economic integration in different regions of the world in order to distinguish key characteristics of efficient model of integration at the post-Soviet space. In particular, authors distinguish the significance of various static and dynamic effects of economic integration for emerging markets and make a conclusion on the rising importance of dynamic effects. It is proved that positive economic effects of integration could be more evident for the emerging markets than for the developed ones. On the basis of a detailed analysis of specific features of economic integration projects in different regions of the world, a conclusion is drawn on key importance for emerging markets of such formats of economic integration that directly contribute to economic development (infrastructure development projects, creation of growth poles, formation of scientific and technological potential, etc.). In the context of globalization the strengthening of cooperation in investment sphere, the implementation of integration projects on financial markets, the creation of common defensive mechanisms against external shocks are of particular significance for economic integration processes.  Basing on the undertaken analysis, the main principles of efficient model of integration in the Eurasian Economic Union are outlined and the key terms of realization of this model are defined. First of all, an efficient model of integration in the Eurasian Economic Union should be formed in contest of interaction between this union, at the one hand, and European and Asian integration centers, at the other hand. Then, integration mechanisms should extend beyond traditional schemes of integration and include different types of agreements (on preferential investment, financial integration and cooperation), sectoral cooperation projects, common policies, etc. Formation of single humanitarian, scientific and innovation environment should become the key element of the integration model of the Eurasian Economic Union.
