The analysis describes the changes in labour input productivity level depending on changing labour and capital relations (fixed assets and current assets) in farms up to 7 ha, 10 ha and greater in the Mid-East Macroregion in 1990, 1991 and 1992. Moreover, the analysis explains the changes of labour input productivity level basing upon labour inputs and capital relation and substitution (isoquant-curve and marginal substitution rate) both in global and partial formulation.
