REGIONAL DIFFERENTIATION OF PRODUCTION FLEXIBILITY AT RURAL GOODS PRODUCING FARMS IN POLAND

摘要

The aim of the study was to identify and examine an elasticity of relations between production factors (land, labour, capital) and incomes gained by using the above mentioned factors at farms of four macro-regions FADN, i.e.: Pomorze and Mazury, Wielkopolska and ?l?sk, Mazowsze and Podlasie, Ma?opolska and Pogórze. Production function models of Cobb-Douglas (C-D) were assessed for every macro-region for years: 2010, 2011 and 2012. The survey shows that in all macro-regions as well as in all surveyed years, elasticity coeffi cient of total net added value was higher than 1 which means increasing incomes in scale. Increase of net added value in three among four surveyed macro-regions depended mainly on land factor while labour input (excluding Mazowsze and Podlasie where labour factor was important) and fi xed assets factor appeared to be of least importance.
