REGRESSION RELATIONSHIP BETWEEN PRODUCTION AND FACTORS OF PRODUCTION IN POLISH AGRICULTURE

Based on the functional dependence of net final output on the land, labour and fixed assets in agriculture in 2009 and 2010, it was determined that the growth rate of the value of the output was more than proportional.The research revealed that labour (number of employed) reduced the relative growth of net final output in agriculture in 2009 and 2010 (-0.246). It transpired that the application of labour in relation to the gross value of total fixed assets was unfavourable, and that the employment of technical devices limited labour efficiency in agriculture.The impact of agricultural land (land) on the relative growth of net final output exceeded 28%, and the impact of the gross value of total fixed assets was approximately 72%; the other factors of production in agriculture in 2009 and 2010 remained unchanged.
