Changes in total productivity were investigated with regard to production factors and internal inputs for the group of 10 large-acreage farms within the period 1997-2000. The Malmquist index and non-parametric data analysis DEA, were used to measure total factor productivity changes. The Malmquist index was decomposed into two component factors: technical change ratio and efficiency change ratio. The results were reported in form of growth rates. Nine objects showed an increase in productivity of total production factors. For the whole group, the average productivity growth rate was 4.6%. Our results indicate that the productivity growth of production factors was mainly accomplished through technical changes rather than the efficiency improvements. One of the 10 farms (farm no 9) displayed the highest average productivity fall both in terms of total production factors and internal inputs. The average total productivity of internal inputs decreased at the annual rate of -4.5%, this fall resulted from considerable decline in technical efficiency since the average rate of efficiency change was -8.5%, as compared to positive rate of technical change, being equal to 4.3%. Within the studied group, 70% farms reached positive growth dynamics of the total productivity of internal inputs. It was shown that majority of studied farms introduced modernization and technological changes what made possible the reduction of labor resources.
