System interpretations study the essence of settlement structure on two ontological planes: on the plane of interactio of elements and on the plane of creating of a separate category of integrity. The ontological substance of interaction consists in the fact that it constitutes the basic mechanism joining elements of the class into a whole. However, freedom of interpretation of the interaction notion results in recognizing the system either as an analogue of an organic system whose purposedly organized elements are kept in dynamic balance, or in treating it as a sui generis convention understood as a useful tool of study. However, with the use of only the interpretation of the substance of interaction mechanisms it is impossible to prove existence of settlement system as a separate category of entity. Between all elements of the class of settlements always there are some interactions, and they can be of mechanical, field or thermodynamic character. However, it is impossible to determine which of the internations have system-creative properties and which are devoid of these properties. These diffilculties cause that settlement theories look for the essence of the system in a class of settlements, constituted into a specific wholeness. This means that a settlement system cannot be constructed by adding elements one by one, thait is it cannot be analysed through application of theories concerning its parts and their interrelations. In other words, an interpretation of a settlement system in system categories resolves itself into recognizing it as an organic whole which requires during in analysis appliiation of irreducible principles of such systems. This is determined by the system's structure which excludes the possibility to analyse it from the so-called „summatiive” point of view. To recognize a settlement system as a separate ontological category requires to show how a „summative” analysis differs from analysis of another „non-summative” type. This differentiation seems to be based on a statement that elements of an organic whole do not behave independently of one another, and one may assume that the principles applying to them when they are not elements of an organic whole, are valid for them as elements of such a whole. Therefore it seems that a „summative” analysis is such which explains properties of a system basing on principles concerning its elements and the prtinciples do not refer to features of the elements as components of a system. And „non-summative” analysis seems to be an analysis describing a system basinig on principles on connections between elements as functional elements of the system. But if these are the differences between such aellegedly different methods of analysis, the differenees are not important. This proves that border between systems cannot be determined aceurately - between „organic wholes” and other systems - „non-summative”. If even elements of summative wholes relate casually to one another (e.g. in gravitational systems), summative analysis of such wholes must contain special assumptions describing organization of elements of such wholes so that a basic theory can be applied to them, similairly to systems recognized as „summative”. This means that from the ontological point of view there is no justification to recognize a „non-summative” whole, which is a substratum of settlement system, as a separate real entity.
Po integracji Polski z Unią Europejską system wsparcia podmiotów działających w sferze agrobiznesu przybrał formę zinstytucjonalizowaną, posiadającą wiele zadań. Podmioty te mają bardzo duży wpływ na funkcjonowanie całego sektora agrobiznesu. Przedstawiono koncepcję nowego zarządzania publicznego jako modelu zarządzania organizacjami publicznymi wdrażającymi politykę rolną i rozwoju obszarów wiejskich w Polsce w procesie europeizacji administracji publicznej.
