Classification of integration associations according to the degree of development of a single transport space

In modern conditions of development of integration processes in the world economy, special importance is attached to the transport sector. The formation of a single transport space (STS) in the regions creates additional opportunities for the economic development of the integrating countries. At the same time, the literature does not pay enough attention to the definition of the essence of the single transport space and the classification of integration associations according to the degree of its development. Therefore, there is a need to develop such a classification. The article substantiates the expediency of classification of integration associations according to the degree of development of a single transport space. The author's formal-logical classification is developed, which is based on three basic types of a single transport space: transport and logistics type provide a positive multiplier of integrated economic growth for all participating countries; innovative-logistic and customs-logistic types cause polarization in the action of the multiplier of integrated economic growth (in particular, both positive and negative growth rates of GDP values of the participating countries are possible); industrial and logistics type provide a zero multiplier of integrated economic growth for all participating countries. The conclusion is made about the possibility of unification and harmonization of transport space in the practice of integration associations on the basis of the developed classification.
