The article contains deliberations concerning the modeling of inflationary phenomena on the scale of the national economy on the basis of data provided by the analysis of situation and functioning of enterprises. Proceeding from an assumption about (mostly) cost character of the Polish inflation in the seventies and the eighties, the author analyzes the process of growth of production costs pointing at them as a direct cause behind price increase. The conclusions which can be drawn from attempts at the modeling of inflationary phenomena constitute a statistical confirmation of theses contained in the article. The main conclusions are: existence of a strong inflation loop in the Polish economy causing that price rises do not constitute an effective way of balancing the market; the functioning of the cost formula of prices, which does not provide proeffectiveness stimuli; decisive role of wages in formation of inflationary phenomena and disequilibrium. Hence the necessity of changing the present mechanisms of the functioning of enterprises, and especially the shaping of relationships between wages, labour productivity and prices.
