摘要：The study evaluated the importance of agricultural production structures for eco- nomic efficiency and environmental sustainability of farms. For this purpose,multi- variate methods were used:ordering and data envelopment analysis (DEA). The study is based on accounting data from the farms of intensive agriculture in Wielkopolska Province,collected by the Institute of Agricultural and Food Economics in Warsaw in 2004-2009. It was demonstrated that diversified farms achieve similar economic ef- ficiency indicators as specialized farms. At the same time it was proven that the farms with production specializing in breeding cattle,implement their function ofguard- ians of the countrysidein”the same degree even better. Thus,the main hypothesis of"the study formulated on the basis of studying literature was rejected. It said that: specialized farms achieve higher economic efficiency with lower environmental sus- tainability of the production than diversified farms. In the diversified farms there is higher environmental sustainability of production at lower economic efficiency than in specialized farms.
