Key words	fertilizers, plant protection products, European Union, Ward method
Abstrakt	Aktualnie duże znaczenie w agrobiznesie mają przemysłowe środki produkcji rolnej, w tym zwłaszcza nawozy mineralne oraz chemiczne środki ochrony roślin. W artykule próbowano przedstawić i porównać zmiany wartości zużytych nawozów i środków ochrony roślin w krajach Unii Europejskiej w latach 2010-2018. Badano zmiany wartości zużytych nawozów i środków ochrony roślin w przeliczeniu na 1 ha UR oraz zmiany udziału omawianych środków produkcji w zużyciu pośrednim. Stwierdzono, że wartość zużytych nawozów i środków ochrony roślin w przeliczeniu na 1 ha UR średnio w UE zwiększyła się. Wzrósł ich również udział w zużyciu pośrednim. W wyniku grupowania obiektów metodą Warda otrzymano 4 skupienia krajów, które różniły się pomiędzy sobą pod względem zaproponowanych cech, natomiast kraje, które tworzyły dane skupienie charakteryzowały się zbliżonymi wartościami zmiennych. Krajami w których zaobserwowano zarówno wyraźny wzrost wartości zużytych nawozów i środków ochrony roślin w przeliczeniu na jednostkę powierzchni jak również zdecydowane zwiększenie ich wartości w zużyciu pośrednim były: Litwa, Bułgaria i Estonia. Spadek popytu na omawiane środki produkcji wystąpił natomiast w Belgii, Chorwacji, Słowenii, Danii, Finlandii oraz w Portugalii.
Abstract	Currently, agricultural means of production are of great importance in agribusiness, in particular mineral fertilizers and chemical plant protection products. The article attempts to present and compare changes in the value of used fertilizers and plant protection products in European Union countries in 2010-2018. Changes in the value of used fertilizers and plant protection products per 1 ha of UAA and changes in the share of these means of production in intermediate consumption were examined. It was found that the value of used fertilizers and plant protection products per 1 ha of UAA increased on average in the EU. Their share in intermediate consumption also increased. As a result of grouping objects using the Ward method, 4 clusters of countries were obtained, which differed in terms of the proposed features, while the countries that created the given cluster were characterized by similar values of variables. The countries where both a clear increase in the value of used fertilizers and plant protection products per unit area as well as a significant increase in their value in intermediate consumption were observed: Lithuania, Bulgaria and Estonia. However, a decline in demand for the discussed means of production occurred in Belgium, Croatia, Slovenia, Denmark, Finland and Portugal.

Tytuł	PROSUMERIC ACTIVITY OF CONTEMPORARY FINAL PURCHASERS VS. THEIR RELATIONSHIPS WITH OFFERORS
Title	Aktywność prosumpcyjna współczesnych nabywców finalnych a relacje łączące ich z oferentami
Słowa kluczowe	final purchaser, relationships, offeror, prosumption
Key words	nabywca finalny, relacje, oferent, prosumpcja
Abstrakt	The article is of a theoretical and empirical nature. To prepare the theoretical part the available literature on marketing and consumer behaviour was cognitively and critically analysed. The results of the analysis allowed for identifying a knowledge gap and a research gap in this area. So far, purchaser activity in the context of relationships and image has not been analysed, especially in relation to offerors perceived as the initiators of communication and creation behaviours of purchasers. Therefore, the aim of the article was to define the significance of mutual relationships between purchasers and offerors in relation to the activity of final purchasers. A research hypothesis was verified: that the perception of offerors as the initiators of the activity of final purchasers differentiates the range of this activity. In order to achieve the goal and check the formulated hypothesis, a nationwide empirical research was conducted. The research involved a questionnaire for collecting primary data, which was afterwards statistically analysed by means of cluster analysis and the Kruskal-Wallis test. The results revealed that good relationships were important or very important for the majority of respondents. The perception of offerors was significant as far as the form of marketing activity for purchasers are concerned. However, it is possible to note statistically significant differentiation in the case of two forms of purchaser activity. So, the research hypothesis turned out to be valid only for these two forms.
Abstract	Artykuł ma character opracowania teoretyczno-empirycznego. Do przygotowania części teoretycznej wykorzystano metodę analizy poznawczo-krytycznej światowej literatury przedmiotu z zakresu marketingu i zachowań konsumenckich. Wyniki tej analizy pozwoliły na zidentyfikowanie luki wiedzy i luki badawczej. Dotychczas bowiem nie analizowano zakresu aktywności nabywców w kontekście relacyjno-wizerunkowym, zwłaszcza w odniesieniu do sposobu postrzegania oferentów jako inicjatorów komunikacyjnych i kreatywnych zachowań nabywców. Dlatego też, celem artykułu było określenie znaczenia, jakie mają wzajemne relacje między nabywcami, a oferentami w odniesieniu do zakresu aktywności nabywców finalnych. Weryfikacji poddano hipotezę badawczą mówiącą, iż sposób postrzegania oferentów jako inicjatorów aktywności nabywców finalnych różnicuje jej zakres. Dążąc do osiągnięcia wymienionego celu oraz sprawdzenia sformułowanej hipotezy przeprowadzono ogólnopolskie badania empiryczne, podczas których do zebrania danych pierwotnych wykorzystano metodę badania ankietowego. Zebrane dane pierwotne poddano analizie statystycznej, w trakcie której zastosowano metodę analizy skupień oraz test Kruskala-Wallisa. Okazało się, że dla większości ankietowanych dobre relacje z oferentami były ważne lub wręcz bardzo ważne. Sposób postrzegania oferentów miał znaczenie, jeśli chodzi o zakres form aktywności marketingowej nabywców. Jednak o zróżnicowaniu statystycznie istotnym można mówić w przypadku dwóch form aktywności. Tym samym więc stwierdzenie zawarte w hipotezie badawczej w przypadku respondentów okazało się prawdziwe tylko dla nich.

Tytuł	Typy gospodarstw domowych ze względu na ich zachowania na rynku żywności
Title	Types of Households by Their Behaviour on the Food Market
Słowa kluczowe	gospodarstwo domowe, typologia, rynek żywności, analiza wielowymiarowa, Polska, Słowacja
Key words	household, typology, food market, multidimensional analysis, Poland, Slovakia
Abstrakt	Dynamiczny rozwój rynku artykułów żywnościowych wymaga od przedsiębiorstw oraz instytucji odpowiedzialnych za politykę gospodarczą kraju ciągłego monitorowania zachowań głównego podmiotu konsumpcji na tym rynku, jakim jest gospodarstwo domowe. Jednym z rozwiązań jest prowadzenie zabiegów typologizacji. Celem artykułu jest zaprezentowanie wyników typologii gospodarstw domowych przeprowadzonych w Polsce i na Słowacji na próbie 900 gospodarstw domowych. Do delimitacji typów gospodarstw wykorzystano hierarchiczną (metoda Warda) i niehierarchiczną (metoda k-średnich) analizą skupień. W rezultacie w każdej podpróbie udało się wyodrębnić trzy typy gospodarstw domowych ze względu na ich zachowania na rynku żywności.
Abstract	The dynamic development of the food market requires enterprises and institutions responsible for the country's economic policy to constantly monitor the behaviour of the main consumption entity on this market, which is the household. One of the solution is to conduct typologisation procedures. The aim of the article is to present the results of household's typology conducted in Poland and Slovakia on a sample of 900 households. Hierarchical (Ward's method) and non-hierarchical (k-means method) cluster analysis was used to delimit households' types. As a result, three types of households were identified in each sub-sample by their behaviour on the food market.

Tytuł	Obszary wiejskie w systemie ekonomiczno-społecznym państw Unii Europejskiej
Title	RURAL AREAS IN THE SOCIO-ECONOMIC SYSTEM OF EU COUNTRIES
Słowa kluczowe	obszary wiejskie UE, ludność na obszarach wiejskich, wartość dodana brutto (GVA)
Key words	EU rural areas, population of rural areas, employment on rural areas, gross value added (GVA)
Abstrakt	W opracowaniu podjęto problem identyfikacji i oceny obszarów wiejskich oraz pośrednich wiejsko-miejskich krajów Unii Europejskiej. Dla wybranych czterech zmiennych opisujących ich; powierzchnię, udział ludności, udział zatrudnionych i wypracowaną wartość dodaną brutto (GVA) wykonano analizy tabelaryczne, analizę skupień oraz dokonano dyskryminacji informacji statystycznej przy zastosowaniu techniki drzew klasyfikacyjnych. Przeprowadzone badania wskazały na wielowymiarowe zróżnicowanie obszarów wiejskich oraz ich duże, choć zróżnicowane znaczenie w ekonomii poszczególnych krajów. Na wydzielonych stricte obszarach wiejskich krajów UE, które stanowią 49,7% powierzchni, zamieszkuje 34,7% ludności, 26,7% znajduje zatrudnienie na wsi, a udział w wypracowanej wartości dodanej wynosi 13%. Analiza taksonomiczna skutkowała wyodrębnieniem trzech grup (skupień) liczących po osiem państw. Polska w tej kompleksowej ocenie obszarów wiejskich jest podobna do Czech, Danii, Francji, Łotwy i Niemiec.
Abstract	The study undertakes the problem of identifying, cataloguing, and evaluating rural areas and intermediate areas of European Union countries, for four selected variables which describe: area, share of population, share of employed, and share of gross value added (GVA). Tabular analyses and cluster analysis ware conducted, and the statistical information was differentiated through classification trees. The research revealed multidimensional diversification of rural areas and their meaningful, although diverse, relevance within the economic systems of individual countries. 34,7% of the EU population reside in strictly rural areas, which make up 49,7% of the EU geographic area. The share of employed in rural areas in the EU amounts to 26,7%. Additionally, the contribution of the rural areas to elaborated gross value added adds up to 13%. The taxonomy resulted in the extraction of three groups (clusters), each containing eight countries. According to that comprehensive evaluation of rural areas, Poland is similar to the Czech Republic, Denmark, France, Latvia and Germany.

Title	Rural Demographic Problem Areas in Poland
Słowa kluczowe	rural areas, demographic problems, Poland
Key words	rural areas, demographic problems, Poland
Abstrakt	Demographic problem areas are perceived as one of the most important types of problem areas and require special research interest. Problem areas conditioned by population factor most often refer to rural areas. Presented article aims to identify and delimit rural demographic problem areas in Poland. The study covered rural areas distinguished on the basis of the classification of the European Commission DEGURBA The analysis enabled to identify depopulation areas, areas with disrupted population reproduction (ie areas of permanent natural decline), areas of permanent outflow of population, areas with impaired population structure by age and areas with disrupted population structure by sex in the group of people of marriage age (20-34 years). To indicate clusters of communes characterised by the presence of the unfavourable demographic phenomena and processes (rural demographic problem areas) the measure of local spatial autocorrelation (Anselin Local Moran's I) was applied. The application value resulting from the research may be the improvement of the effectiveness of public intervention carried out as part of the development policy.

Słowa kluczowe	sklepy specjalistyczne, postawy prozdrowotne, konsument, żywność wysokiej jakości, cechy socjodemograficzne
Key words	specialist shops, health attitudes, consumer, high quality food, socio-demographic characteristics
Abstrakt	Celem pracy była ocena postaw prozdrowotnych konsumentów nabywających żywność w sklepach specjalistycznych. Określono rodzaj i częstotliwość zakupu żywności oraz dokonano klasyfikacji respondentów ze względu na prezentowane postawy prozdrowotne. Badania zrealizowano metodą pomiaru sondażowego, techniką bezpośrednią. Ogółem przeprowadzono 190 wywiadów. Wyniki badań wskazują, iż dla klientów sklepów specjalistycznych zdrowotność spożywanej żywności ma duże znaczenie. Zwracają uwagę na jej skład kupując produkty naturalne z jak najmniejszą ilością konserwantów, jak najmniej przetworzone. Konsumenci ci są skłonni zapłacić więcej za produkty gwarantowanej jakości. Wyodrębniono trzy skupienia zróżnicowane pod względem postaw prozdrowotnych reprezentujące odpowiednio: 22, 18 i 60% badanej populacji. Skupienie 1 reprezentowane było w większości przez mężczyzn nie dbających o ilość zjadanych kalorii oraz nie zgłębiających wiedzy na temat zdrowego odżywiania, z kolei zwracających uwagę na jakość kupowanej żywności, gotowych zapłacić więcej za produkty gwarantowanej jakości. Natomiast skupienie 2 skupiało głównie mężczyzn o umiarkowanych postawach prozdrowotnych, niezainteresowanych tematyką zdrowego odżywiania. Najliczniej reprezentowane skupienie 3 w przewadze stanowiły kobiety cechujące się silnymi postawami prozdrowotnymi, dbające o ilość spożywanych kalorii, poszukujące i zgłębiające informacje dotyczące zdrowego odżywiania.
Abstract	The aim of the paper was to assess pro-health attitudes of consumers purchasing food in specialist stores. The type and frequency of food purchase was determined and respondents were classified due to pro-health attitude. The research was conducted using personal interview. A total of 190 interviews were gathered. The results showed that for customers of specialist stores, healthiness of consumed food is significant. They pay attention to its ingredients buying natural products with low content of preservatives, less processed. These consumers are willing to pay more for guaranteed quality products. Three clusters of pro-health attitudes representing: 22, 18 and 60% of surveyed population were distinguished. Cluster 1 was represented mostly by men who do not care about the amount of calories consumed and do not interested in knowledge about healthy eating. This group pay attention on purchased food quality, and they are able to pay more for guaranteed quality products. Whereas cluster 2 focused mainly men with moderate pro-health attitudes, not interested in expanding nutrition knowledge. The most-represented cluster of 3 was predominantly women with strong pro-health attitudes, counting consumed calories, seeking and exploring healthy eating knowledge.

Title	Alternative Local Food Shopping Communities in Hungary
Słowa kluczowe	local food, consumer communities, food consumer behaviour, questionnaire study, cluster analysis
Key words	local food, consumer communities, food consumer behaviour, questionnaire study, cluster analysis
Abstrakt	As a result of concerns about the long-term sustainability of globalized retail trade and the stronger presence of health conscious consumer behaviour, governments and groups of conscious consumers worldwide are increasingly focusing on the promotion and development of local food systems and small-scale retail chains and the production of quality local food products to promote the market. In our paper, we would like to give an overview of community-led alternative types of local food systems, with particular attention to shopping community-type consumer and consumer communities. We also describe the main results of our primary research in the population and the shopping community. During the questionnaire we revealed general consumer behaviour and the demand and attitude of local food, the popularity of the customer communities in the settlement of the respondents. In the survey conducted among members of the consumer community, we looked at the analytical areas designated as a target in the population questionnaire for the purpose of comparability and our aim was to explore the sociometrics and lifestyles of communities as well as their community experiences and possible developments. Our hypothesis is that there is a close correlation between the respondents with higher education and income and the preferences of local food. Furthermore, it is assumed that there is a significant difference between the food consumption behaviors of the two samples examined.

Title
Słowa kluczowe	knowledge management, shared services centres, business process outsourcing
Key words
Abstrakt	Nowadays, we can observe in different business and academicals environments an ongoing dialog about knowledge – based economy, due to the fact, that economies are increasingly based on knowledge and information. Practically it means, that companies have started looking for answers for plenty important questions – what ‘knowledge’ exactly means and what kind of knowledge is significant from business continuity perspective? What exactly is a driver of productivity and economic growth? Business executives have to face also other challenges: how all this knowledge has to be managed and how to adapt to swiftly changing circumstances? Should it be centralized in shared services centres forms or maybe outsourced based on business process outsourcing strategy? Do companies should establish cooperation with universities or R&D institutes based on the cluster structure? In this article the author will characterized the knowledge as a source of competitiveness, increasing importance of science and try to summarize best practices in that field.

Tytuł	WOMEN’S LABOUR MARKET ACTIVITY IN THE AGRICULTURE SECTOR IN POLAND AND EUROPEAN UNION IN 2016
Title
Słowa kluczowe	labour market, female employment, cluster analysis, k-mean method
Key words
Abstrakt	The European authorities pay particular attention to agriculture and employees in this sector. Women represent more than 33% of this group in the European Union. A significant number of actions are targeted at women from rural areas, having regard to the mentioned issues and specific situation of women in the labour market. Therefore, it requires in-depth analyses. The main aim of the presented study is to assess the diversity of the situation of women working in agriculture across the EU. The quantitative analysis allows to indicate similarities and differences among EU states in the current structure of women’s employment in this sector. In the analysis, the k-mean method is applied with the Labour Force Survey data from the year 2016. The study refers to 28 EU states and a group of women aged 20–64. The obtained results indicated that we have a large proportion of self-employees in agriculture. However, we observe a larger percentage of those who create jobs for others states that are better economically developed. This analysis confirms the findings that the Polish structure of female employment is closer to those in the Mediterranean countries. Poland is assigned to one cluster with Greece. This group is distinguished by several factors. Firstly, it contains a high proportion of people employed in agriculture with a relatively small share of part-timers. Secondly, it is a very high rate of self-employed with a very low proportion of those who create jobs for others.

Tytuł	CONSUMPTION PATTERNS AMONG ONE-PERSON HOUSEHOLDS OF NEVER MARRIED IN POLAND
Title
Słowa kluczowe	single-person households, consumption, goods, services
Key words
Abstrakt	The scientific objective of the study was to identify consumption patterns in one-person households of never- married women and men, living independently. Ward’s grouping method make possible to establish the number of households’ clusters. The final stage of household grouping procedure, regarding consumption expenditures was accomplished with k-means clustering method. It can be concluded that distinguishing the consumption patterns for one-person households of never married is possible on the basis of diversification both level and structure of incomes in these households as well as socio-demographic differences between them. Depending on economic and socio-demographic variables, disparate consumption patterns for these types of households can be observed. In addition, it’s worth stressing that household having different level of income (although coming from similar source) but similar demographic structure show greater similarity than households having similar financial situation.

Słowa kluczowe	spółdzielnie energetyczne, klastry energii, energia odnawialna, rozwój lokalny
Key words	energy co-operatives, energy clusters, renewable energy, local development
Abstrakt	W polityce energetycznej wykorzystywane są różne formy organizacyjne. Na szczeblu lokalnym i regionalnym doskonale sprawdzają się spółdzielnie energetyczne i klastry energii. Ich główne zalety to: uspołecznienie procesu wytwórczego, łączenie celów społecznych i ekonomicznych oraz korzystny wpływ na poprawę stanu środowiska naturalnego. Celem artykułu było rozpoznanie warunków i stanu rozwoju spółdzielni energetycznych i klastrów energii w Polsce i ich wpływu na rozwój lokalny oraz całego sektora energetycznego na tle doświadczeń niemieckich. W Niemczech funkcjonuje najwięcej spółdzielni energetycznych w Unii Europejskiej. Prowadzą one do rozwoju na szeroką skalę energetyki obywatelskiej, w której integrują się interesy wytwórców i konsumentów energii. Przeprowadzona analiza pozwoliła wywnioskować, że spółdzielnie energetyczne powinny mieć elastyczne struktury wynikające z lokalnych potrzeb i możliwości, zaczynając od spółdzielni socjalnych do struktur funkcjonujących w formie klastrów o zasięgu regionalnym.
Abstract	In energy policy, various organizational forms are used. At local and regional levels, energy cooperatives and energy clusters are perfect. Their main advantages are: socialization of the production process, combining social and economic goals and a beneficial effect on the improvement of the natural environment. The aim of the article was to recognize the conditions and state of development of energy cooperatives and energy clusters in Poland and their impact on local development and the entire energy sector as compared with similar activities in Germany. Germany has the largest number of energy cooperatives that operate in the European Union. They lead to the development of civic energy in which the interests of energy producers and consumers are integrated on a large scale. The conducted analysis led to the conclusion that energy cooperatives should have flexible structures resulting from local needs and possibilities, starting from social cooperatives to structures functioning in the form of regional clusters

Słowa kluczowe	ASF – afrykański pomór świń, rynek mięsa wieprzowego, eksport, Polska
Key words	ASF – African swine fever, pork market, exports, Poland
Abstrakt	Celem badania jest ocena oddziaływania wirusa afrykańskiego pomoru świń ASF (African Swine Fever) na rozwój i funkcjonowanie rynku mięsa wieprzowego w Polsce. Wirus ten pojawił się w Polsce w lutym 2014 roku u dzików, a następnie w lipcu 2014 roku u świń. Badanie obejmuje lata 2014-2018, czyli okres występowania wirusa ASF w Polsce. Do końca lipca 2018 roku odnotowano 182 przypadki ASF u świń i ponad 2,6 tysiąca u dzików w czterech województwach wschodniej i centralnej Polski, a największe skupisko tej choroby zlokalizowane jest w województwie lubelskim. Pojawienie się wirusa ASF negatywnie wpłynęło na rynek mięsa wieprzowego w Polsce, skutkując ograniczeniami w eksporcie tego mięsa, kosztami likwidacji ognisk choroby i bioasekuracji. Mimo tych trudności produkcja mięsa wieprzowego w Polsce w latach 2014-2018 odznaczała się tendencją wzrostową, a eksport jedynie w pierwszym roku występowania ASF obniżył się, w kolejnych latach, w związku z dywersyfikacją rynków zbytu, odnotowano jego wzrost. Do badania zastosowano metodę opisową i proste analizy statystyczne.
Abstract	The aim of the study is to assess the impact of African swine fever virus (ASF) on the development and functioning of the pork market in Poland. This virus appeared in Poland in February 2014 in wild boars, and then in July 2014 in pigs. The study covers the years 2014-2018, the period of ASF virus in Poland. By the end of July 2018, there were 182 cases of ASF in pigs and over 2.6 thousand in wild boars in four provinces of eastern and central Poland, and the largest cluster of this disease is located in the Lublin province. The appearance of ASF virus has had a negative impact on the pork market in Poland, resulting in restrictions on the export of this meat, costs of eradication of outbreaks and biosecurity. Despite these difficulties, the production of pork at this time was characterized by an upward trend, while exports only in the first year of the ASF decreased, but in subsequent years, due to the diversification of markets, there was an increase in exports. The descriptive method and simple statistical analyzes were used for the study.

Title	Profit Efficiency in EU FADN Farms under Different Types of Agriculture
Słowa kluczowe	efficiency analysis, DEA, FADN, farm income, models of agriculture
Key words	efficiency analysis, DEA, FADN, farm income, models of agriculture
Abstrakt	The aim of the paper was to assess the profit efficiency in representative farms in FADN regions operating in various types of agriculture. For this purpose, clusters of FADN regions with relatively similar dominant types of agriculture were selected on the basis of their partial productivity indicators. Then, efficiency indicators were calculated for each region, using various types of DEA models. The data were adapted from FADN and covered the 2004 and 2015 period. On the basis of analysis conducted in the article, it was found that the farms located in Mediterranean regions were the most efficient. At the same time, in the cluster covering the regions with the most modern agriculture, the efficiency was at a very low level. Farms in most regions operated under the conditions of decreasing economies of scale, although the efficiency of scale itself improved. Moreover, in contrast to 2004, an increase in efficiency in relation to the best practice frontier was observed in 2015.

Moreover, in contrast to 2004, an increase in efficiency in relation to the best practice frontier was observed in 2015.

Tytuł	Zatrudnienie a intensywność rolnictwa państw Unii Europejskiej
Title	Employment and Intensity of Agriculture of European Union Countries
Słowa kluczowe	zatrudnienie, intensywność rolnictwa, państwa Unii Europejskiej
Key words	employment, agriculture intensity, European Union countries
Abstrakt	Celem artykułu jest omówienie zatrudnienia w kontekście intensywności w rolnictwie państw Unii Europejskiej na podstawie wybranych cech. Analizę przeprowadzono dla 2016 roku. Badanie przeprowadzono za pomocą analizy skupień. Do analizy przyjęto następujące cechy diagnostyczne: udział ludności czynnej zawodowo w rolnictwie z niskim poziomem wykształcenia w całkowitej liczbie ludności czynnej zawodowo (%), udział ludności zatrudnionej w rolnictwie w ludności zatrudnionej ogółem (%), produktywność pracy w rolnictwie (EUR/AWU), udział wartości dodanej dostarczanej przez sektor rolniczy (%), udział użytków rolnych zarządzanych przez gospodarstwa o dużej intensywności w użytkach rolnych ogółem (%) oraz średnia ekonomiczna wielkość gospodarstw (SO/gospodarstwo w EUR). W wyniku zastosowania analizy skupień podzielono badane państwa na cztery grupy. Zgodnie z wynikami w państwach o wysokim poziomie zatrudnienia w rolnictwie zwykle mniejszy jest udział wartości dodanej dostarczanej przez sektor rolniczy. Natomiast w państwach o niższym udziale zatrudnionych w rolnictwie intensywność rolnictwa jest z reguły większa.
Abstract	The objective of the article is to discuss employment in the context of the agriculture intensity in European Union countries based on selected features. The analysis was conducted for 2016. Research was examined using the cluster analysis. The following diagnostic features were used for the analysis: share of working population in agriculture with low educational attainment in total working population (%), share of working population in agriculture in total working population (%), labour productivity in agriculture (EUR/AWU), distribution of GVA by primary sector (%), share of UAA managed by farms with high input intensity per ha (%), average economic farm size (SO/holding in EUR). As a result of the cluster analysis, the examined regions were divided into four groups. According to the results, in countries with high levels of employment in agriculture, the share of added value provided by the agricultural sector is usually smaller. However, in countries with a lower share of people employed in agriculture, the intensity of agriculture is usually higher.

Title	Demand for Agricultural Mechanization Services in the European Union Countries
Słowa kluczowe	usługi rolnicze, usługi mechanizacyjne, popyt, Unia Europejska
Key words	agricultural services, mechanization services, demand, European Union
Abstrakt	Korzystanie z usług mechanizacyjnych może w istotnym stopniu przyczyniać się do obniżania kosztów produkcji umożliwiając producentom rolnym bezinwestycyjne wdrożenie postępu technicznego. W artykule próbowano określić tendencje występujące w popycie na rolnicze usługi mechanizacyjne w krajach Unii Europejskiej w latach 2010-2017. Badano zmiany wartości usług w przeliczeniu na 1 ha UR oraz zmiany udziału usług mechanizacyjnych w zużyciu pośrednim. Stwierdzono, że wartość usług w przeliczeniu na 1 ha UR średnio w UE zwiększyła się. Wzrósł również udział usług w zużyciu pośrednim. W wyniku grupowania obiektów metodą Warda otrzymano 5 skupień krajów, które różniły się między sobą pod względem zaproponowanych cech, natomiast kraje tworzące dane skupienie charakteryzowały się zbliżonymi wartościami zmiennych. Krajami w których zaobserwowano zarówno wyraźny wzrost wartości usług mechanizacyjnych w przeliczeniu na jednostkę powierzchni jak również zdecydowane zwiększenie wartości usług w zużyciu pośrednim były: Finlandia, Niemcy, Łotwa, Rumunia oraz Estonia. Wyraźny spadek popytu na usługi mechanizacyjne wystąpił natomiast w Grecji i na Litwie.
Abstract	The use of mechanization services can significantly contribute to reducing production costs, enabling agricultural producers to implement technical progress without any investment. The article attempted to identify trends in demand for agricultural mechanization services in the European Union countries in 2010-2017. Changes in the value of services per 1 ha of UAA and changes in the share of mechanization services in total expenditures incurred for agricultural production were examined. It was found that the value of services per 1 ha of UAA on average in the EU increased. The share of services in intermediate consumption has also increased. As a result of grouping objects by the Ward method, 5 clusters of countries were distinguished, which differed among each other in terms of the proposed features, while the countries that created the focus were characterized by similar values of variables. The countries in which both a clear increase in the value of mechanization services per unit area was observed as well as a significant increase in the value of services in indirect consumption were: Finland, Germany, Latvia, Romania and Estonia. A clear decline in demand for mechanization services occurred in Greece and Lithuania.

Słowa kluczowe	agricultural economics, emissions, classification, cluster analysis, k-means, hdbscan
Key words	agricultural economics, emissions, classification, cluster analysis, k-means, hdbscan
Abstrakt	Agricultural emissions represent greenhouse gas emissions from crop and livestock production. There are various estimates on agricultural emissions, however on average about 14 to 25 percent of total global emissions comes from agriculture. The main goal of this paper was to present distribution of agricultural emissions among OECD countries with the help of clustering analysis. Clustering analysis is one of the tools used in the field of exploratory data mining. Two methods were used in the analysis: K-means and HDBSCAN algorithms. Both techniques are part of unsupervised learning tasks, which group data into multiple clusters. Finally, an appraisal of obtained classifications was performed.

Tytuł	EU FUNDS (RDP) AND THEIR IMPACT ON LOCAL DEVELOPMENT
Title
Słowa kluczowe	local development, Hellwig’s method, Ward’s method
Key words
Abstrakt	The paper presents the results of research aimed at determining the impact of the use of EU funds on local development on the example of voivodeships. The first stage of the research was performed with the use of Hellwig’s development model method. It was aimed at classifying individual voivodships and assigning them to one of four groups in terms of their level of development. The next stage was to check whether the examined features proving the level of local development are also related to the level of use of EU funds under RDP. In the third stage, the analysis of Ward clusters was used and answers were sought as to whether the units which are clustered together in terms of the level of use of EU funds are at the same time included in the same groups in terms of the level of local development.

Tytuł	QUALITY OF LIFE IN POLISH FARMERS’ HOUSEHOLDS ASSESSMENT WITH TOPSIS METHOD
Title
Słowa kluczowe	quality of life, class typology, TOPSIS, farmers’ households
Key words
Abstrakt	The aim of the research was a multidimensional assessment of the quality of life in farmers’ households along with its synthetic measure and a typology of household classes, rendered by the measure. The 2015 data on 730 farmers’ households were used to analyse their quality of life in nine dimensions: material living conditions, employment, health, education, leisure and social relations, economic and physical security, civic participation, environmental quality, and the subjective assessment of well-being. Due to concomitance of features measured on metric and non-metric scales, generalized distance measure (GDM) was applied as part of the TOPSIS method to determine the distance of objects from the model values. The study drew on microdata from the Social Diagnosis survey conducted in 2015 by the Council for Social Monitoring, and employed clusterSim R-package for calculations.

Tytuł	USE OF AGRICULTURAL SERVICES IN EUROPEAN UNION COUNTRIES
Title
Słowa kluczowe	agricultural services, European Union
Key words
Abstrakt	The purpose of this paper is to assess the use of agricultural services in European Union countries in the context of selected features of agriculture. The Ward’s Method was used to isolate six typological clusters of European Union countries. It may be noticed that clusters with a high levels of fixed capital consumption and total intermediate consumption are characterized by a higher use of services than other clusters. The absence of a noticeable relation between the share of crop output in the structure of agricultural output, or between the labour input and the use of agricultural services can be explained by differences in natural conditions, traditional farming models and preferences in choosing between developing the farm’s own machinery or using services.
