Trade, as a term, means the exchange of products and offering services between manufacturer and buyer. In terms of importance, in the total GDP of the Republic of Croatia, it is in second place, just behind the manufacturing industry. A large role in the exchange of products and offering services to customers is offered by retailers whose task is mediate between producers and consumers or between wholesaler and consumers. Of great importance were also forms in which retail takes place because nowdays the influence of other forms of sales is growing stronger, and others sold less and less sales through excessive retail channels. Various researches show that Croatian retail is going through big changes with great similarities to the changes in Europe. The main changes in retail are happening through the processes of concentration, modernization, diversification, standardization and internationalization. New formats, organizational structures and new managerial skills have been largely implemented in Croatian retail. Many theorists believe that location is the most important criterion for the success or failure of retail, although nowdays the influence of information technology is growing stronger, changing the patterns of ordinary sales. The aim of this paper is to make a research in order to make an analysis of the retail structure and explain the difference in the representation of independent and planned retail agglomerations in the western part of the City of Zagreb.
