Identification of agriculture types in Poland with analysis of spatial associations. The aims of the paper were to identify and characterize contemporary agriculture types in Poland, and evaluate the suitability of the typology used. The analysis was performed on the basis of territorial units (communes, LAU2). The study involved a total of 68 variables characterizing agriculture. Spatial associations found in the data were identified. As the next step, an analysis of local spatial autocorrelation was performed and spatial clusters were identified by LISA and cluster analysis performed by the method of k-means clustering, which identified a total of five agriculture types. The study presented the spatial distribution of individual types of agriculture and their characteristics. Furthermore, the method was shown to be especially useful for investigating agricultural phenomena characterized by a large number of traits in relation to a large number of territorial units.

The aim study is the development of the classification of agricultural enterprises, based on the properties of the distribution of enterprises depending on the size of the land bank. To achieve this aim, open databases of agricultural enterprises were used, from which data for the Dnipropetrovsk district were selected. The data is not official. They are collected according to the data provided by the agricultural enterprises themselves. Since the official statistics group of small enterprises with up to 200 ha of land includes a fairly large number of enterprises that exist only formally, and since actively functioning enterprises are voluntarily registered in the databases used for the study, the developed classification reflects the real situation with agricultural enterprises in the Dnipropetrovsk district. The proposed scheme of a grouping of agricultural enterprises is regular, logarithmically uniform and based on the exponential increase of the land bank of agricultural enterprises. Its parameters are chosen in such a way as to take into account the classification of farms used in the Tax Code of Ukraine. The developed grouping of agricultural enterprises was used to analyze such characteristics of enterprises as types of production and organizational and legal forms of management. The analysis of the distribution showed that with the decrease of the land bank the number of farms increases and the number of enterprises, whose forms of management are joint-stock companies of different types, decreases.
