The purpose of this paper is to study the economic efficiency of the autumn wheat with the help of the multi-factorial regression models. Assessing the elasticity coefficient of production factors in the agrarian sector of the Republic of Moldova gives the possibility to define the criteria for optimizing the land consolidation. By means of these assessment methods we can appreciate the existence, direction and the degree of interrelatedness between the economic processes. We can also measure the degree of variation of endogenous characteristics under the influence of the exogenous characteristics in growing autumn wheat in the district of Făleşti, the Republic of Moldova.
