Therefore, this study aims to investigate and present the intensity of the trend of concentration of distributive trade in the world, in countries that concentrate most of the global distributive trade.

In the second part, the study shows the regional analysis of concentration of trade (the European Union, the USA, Japan, China and Russia). Anaysis of the concentration of trade network shows the trend toward reducing the number and increasing the size of the trade enterprises and stores.
