摘要：The conducted correlation-andregression analysis revealed a close inverse connection between the functional characteristic "share of the expenditures for food and non-alcoholic beverages in the structure of the total expenditures of the households" and the factorial characteristic "GDP per capita by purchasing power parity, at constant prices". The response of the share of food expenditures in the structure of the total expenditures of the households to per capita GDP growth corresponds to the law of diminishing returns. The pattern is manifested in the long-term period.
