This article presents some considerations on chosen determinants of the consumer purchasing behaviour. The consumer purchasing behaviour is affected by different factors associated with living in a society, an organized community as well as factors of personal nature, which can be grouped into collective categories. Psychological, sociocultural, economic and demographic determinants were presented. An attempt to identify interrelationships amongst groups of factors as well as internal relations within the group was made. Purchasing behaviours are subject of interest to social sciences. Their presence in the determined form and their intensity are the resultant of influencing the consumer with factor of the psychological, demographic, economic and sociocultural nature. Factors from different groups also interact with each other, strengthening or weakening the power of influence. Determinants of consumer purchasing behavior described at a group of general issues and complex. They do not apply directly to specific events in a specific time and place. However, they are derived from the conclusions of different studies. They are important in economic theory, as it allows to generalize the different stimuli, indicating their common properties. To understood them good, it is necessary to show their full sizes. To analyze the factors influencing consumer purchasing behavior at the selected level of economic phenomena, in relation to a particular buyer’s market, it is necessary to “translate” them into observable in real economic life events. Added context will manifest full cognitive value of reported factors.
