Opis:
The article presents the evaluation of the financial situation of commercial banks in Poland. The ratio analysis shows that the biggest variations between analyzed units were in productivity of tangible fixed assets, share of non-performing loans and overall liquidity. The financial indicators constituted the basis for the process of grouping banks into clusters of similar financial standing. The use of Ward method enabled us to differentiate five clusters. The most profitable banks belong to the first cluster, while the most productive ones are from the fourth cluster. The third cluster comprises the banks with the relatively worst financial situation.

Opis:
W pracy przedstawiono ocenę stabilności klasyfikacji województw Polski pod względem poziomu życia w latach 2002-2009. Dobór cech diagnostycznych został przeprowadzony w sposób dynamiczny, dzięki czemu otrzymany zestaw cech końcowych jest aktualny nie tylko w okresie badanym, ale także w przyszłości. Do klasyfikacji województw zastosowano metodę Warda oraz sprawdzono dopasowanie dendrogramów do macierzy odległości D za pomocą współczynnika korelacji kofenetycznej, wskaźnika całościowego dopasowania i miary STRESS. Wykorzystując wskaźniki podobieństwa wyników klasyfikacji stwierdzono, że klasyfikacje charakteryzują się dość dobrą stabilnością w czasie.
The work presents evaluation of the results stability of the Polish regions’ classification in terms of a living standard. The research covered the period 2002-2009. Selection of diagnostic features was carried out in a dynamic way, so that the final set of features is valid not only in the period considered, but also in the future. For the regions’ classification Ward’s method was used and the fit of dendrograms distance to matrix D was checked by using the cophenetic correlation coefficient, the indicator of the overall fit and the STRESS measure. Using the similarity indices of the classification results, it was found that the classifications have a fairly good stability in time.

Metoda Wzorcowa Hellwiga pozwala na dokonanie klasyfikacji gmin pod względem konkurencyjności, a metoda analizy skupień Warda okazała się pomocna do klasyfikacji gmin według podobieństwa względem przyjętych zmiennych.
Streszczenie (jęz. angielski) - The paper presents an attempt to use both quantitative and qualitative veriables to analyze complex phenomena. First part of the paper focuses some normalisation methods that often occur in empirical works regarding their characteristics. Special attention concerns zero unitarization method due its adequacy in normalising both quantitative and qualitative veriables. The latter part of the paper presents the metod of quantification and normalization chosen qualitative variables. The whole procedure of normalization, construction of synthetic variable and ranking is illustrated by empirical example. Results of research on the competitiveness of communes in Lubelskie voivodeship consented with the use of multi dimensional methods are presented in the article. Two methods: Hellwig development pattern and Ward aggregation analysis were used in the work. The Hellwig pattern method enable the classification of communes according the level of competitiveness while Ward aggregation analysis is helpful for classification of communes according variables used in research Results of research on the competitiveness of communes in Lubelskie voivodeship consented with the use of multi dimensional methods are presented in the article. Two methods: Hellwig development pattern and Ward aggregation analysis were used in the work. The Hellwig pattern method enable the classification of communes according the level of competitiveness while Ward aggregation analysis is helpful for classification of communes according variables used in research The aim of the study was to show the analogy in the changes in the structure of household expenses in the chosen EU countries and Poland between1988 and 2009. The direction and pace of the changes in the budgets of Polish households can be predicted by using the principle of analogy. Classification of the objects has been carried out based on the modified kmeans method. Three classes of similarities have been distinguished. The structure of Polish households budgets from 2004 – 2008 has turned out the most similar to the structure of the expenses of Portuguese households from 1988 – 2005. In this work we analyzed the changes of the structure of value of agriculture products’ exports in Poland during 1980 – 210 in comparison to other EU countries. In this comparative analysis we chose those EU countries whose largest fraction of exports is constituted by agriculture products: Germany, France, Great Britain, Netherlands, Spain and Italy. To study the changes of the structure of export of agriculture products during those 31 years we used multidimensional analysis methods: Gini index and GCCA – Grade Correspondence Cluster Analysis. To visualize the differentiation of structures of export of agriculture products we used overrepresentation maps (prepared in GradeStat). Analysis was based on 9 groups of agriculture products in million USD: live animals (S2-00), meat and preparations (S2-01), dairy products and birds’ eggs (S2-02), Fish, crustacean and molluscs, and preparations thereof (S2-03), cereals and cereal preparations (S2-04), vegetables and fruit (S2-05), suger, suger preparations and honey (S2-06), coffee, tea, cocoa, spices, and manufactures thereof (S2-07), feeding stuff for animals (not including unmilled cereals (S2-08), miscellaneous edible products and preparations (S2-09). The completed studies have shown a large differentiation of the structure of export of agriculture products in all researched countries. However, the largest differentiation was present in Poland. A significantly high dynamic of growth was observed within three groups of products: dairy products and birds’ eggs (S2-02), Fish, crustacean and molluscs, and preparations thereof (S2-03), vegetables and fruit (S2-05). The participation of those groups in the country’s export has been steadily growing. On the other hand, the participation of until now standard groups of agriculture products (unprocessed: live animals (S2-00) and meat and preparations (S2-01)) has been decreasing.

The paper presents an investigation within the subject of fuzzy methodology concerning some phenomena, which is the consequence of their fuzzy nature. In order to illustrate some fuzzy procedures and their results an empirical example is included. The paper presents the forecast of agrarian structure of voivodships up to 2020 according to typological groups. The data were taken from Statistical Yearbook of Agriculture edited by Central Statistical Office. The forecast was based on the method of structures’ forecasting proposed by Nowak. Then, on the basis of fuzzy classification method, the prediction of spatial differentiation of the structure under investigation up to 2020 was evaluated. The forecast presents what kind of changes in agrarian structure of voivodships will take place if the direction and rate of changes within the period of 2002 – 2009 remain stable. Investments of local communes are intentional expenditures of capital aimed at increase in tangible and intangible benefits of the commune. All effective expenditures born by the commune on construction and reconstruction of its wealth are treated as funds positively influencing its development and well-being of citizens. The paper was intended to assess the level of dispersion, i.e. concentration of expenditures on investments born by 19 cities acting as counties in Silesian voivodship. The fundamental measure used in research was concentration coefficient proposed by Karol Kukuła and the basis for calculations was data presented in budget usage collected by Regionalna Izba Obrachunkowa in Katowice. The regression theory involves methods and tools of exact description of relations between various types of phenomena. Since many years, it is used for the economic and econometric models formulation, however, as the analyze of literature indicates, regression is understood in different ways. This article is a reflection on the application of quantitative methods in economics processes modeling, with particular emphasis on the relations between them, expressed by regression.

The article shows the practical application of the Analytic Network Process in solving decision problems from the field of management. The ANP Model proposed in this paper includes all kinds of dependencies and feedback between decision-making elements in the area of manufacturing management, reflecting the complexity of the problem and actual compounds that occur both between the agents within the company as well as in its surroundings. The paper emphasises the possibility of using experts’ opinion, who gave importance (specifying the validity) of decision-making elements using pairwise comparisons, allowing the identification of factors and the evaluation of their impact on the increase in the volume of production.

Entering into European Union and financial markets crisis left their stamps on Polish economy. Land market was influenced by these changes the most significantly since December 5, 1989, when new regulations concerning free transactions in land appeared. In the nineties farmland was treated as an additional superfluous ballast, however, together with Polish accession to EU it became one of the most popular alternative investments bringing profiteers huge profits in short term. Unfortunately, financial crisis trundling on the real estate market sadly revised investors’ optimistic plans. Abortive investments in too expensive lands without possibility of being transformed into building terrains became problems to people without appropriate knowledge and skills who had wanted to earn quickly. Currently, despite of spreading fashion of land purchase, the market has been weakened significantly. It can be admitted that finally the farmers instead of profiteers are interested in land purchase, which is the beginning of situation stabilization and the first sign of market maturity. Calculus of variations and optimal control theory are on one hand side intensively developing mathematical theories on the other at the center of both of them lies investigating of extremal problems. In connection with extremal problems there naturally arise questions important for mathematics and applications: 1) does there exist a solution of the problem? 2) is the solution unique? 3) how to really find the solution? For problems with constrains, a general principle was proposed by Lagrange. This idea can be generalized far beyond the limits of the problems that he considered. In the paper we present unified formulation of problems of calculus of variations and optimal control in connection with Lagrange principle. There is a 5:1 ratio between the number of households and business entities. This ratio is considered “quantum satis”. The purpose of this paper is to estimate level of local government unit’s financial independence in eastern Poland. For this purpose it was used multidimensional statistical analysis allowing to describe complex effect with help of one variable, so called value of synthetic variable (Hellwig’s method, additive aggregation function).

A number of recent papers on the management of the stock portfolio describes the advantages of the naïve diversification. The naïve strategy performs similarly to the ones which use sophisticated mathematical models. In this paper the strategy is presented which statistically significantly overperforms the naïve strategy. The aim of the paper was to make an attempt to assess the influence of belonging to selected population groups on the size of flows between different states of economic activity, as well as to determine the nature of unemployment found in the various population groups, especially among the rural population. The research showed that the changes in economic activity are mainly affected by structural factors, but in some population groups it is possible to improve the employment situation through actions towards an improvement of the prosperity on the market of goods and services.

Dynamic development of organic farming in Poland is observed since 2004. At that time were introduced the subsidies to organic agricultural production for farms with the certificate of conformity and were in the course of the changes. The aim of this study is to present the dynamics of growth of the number and size of organic farms and the number of organic ecological factories in Poland in the years 2004-2010 and the designation of the forecasts for the next three years. To designate the forecasts of investigated phenomena it was used extrapolation of models of development trends method. In this paper we discuss the development of the rural population in Poland over the past 60 years and the latest demographic projections of Central Statistical Office. The main objects of our attention are the demographic processes in rural-urban cross-section. Poland belongs to the less urbanized countries in Europe. Among Polish neighbors, a lower proportion of urban population is only in Slovakia. However, in the past, differences in the level of urbanization between Poland and other European countries were much higher. In the years 1950-1990 the percentage of urban population in Poland increased from 35 to 62%. However, since 1990. share of rural population has ceased to fall and in the last few years have seen a decline in urbanization even in our country. The main reason for the change is a systematic change in the directions of rural-urban migration. More and more urban population moves to the village. Quite interestingly, this process began much earlier than the changed political system in Poland. Since 1975. decreases systematically negative balance of net rural-urban migration. Since 2000. more and more of the population migrates to the country than comes out. We also pay attention that a similar phenomenon of the growing importance of the share of rural population also occurs in other countries. However, while Poland is following the European countries also in the sphere of customary transformation, the village population seems to be the mainstay of traditional family values.

In this article, the problem of optimization of crop production was formulated as nonlinear generalized transportation problem. As a solution the author proposed generalized quasi-basis method. The illustrative example completes the presentation. The study exemplifies an application of the multidimensional comparative analysis aiming at quantification of international competitiveness of the agri-food economy. The international competitive position was equated to a form of a synthetic measure. The coefficients trends allowed quantifying perspectives of equalization of international competitiveness levels between countries. The empirical investigation identified six patterns of the observed interdependences. Convergence should not be expected in the whole set, but in subgroups of objects. In the light of the Central Statistical Office data from 2010, farm equipment is shows very high differentiation in spatial aspect across Poland. The paper presents an attempt to construct ranking of voivodships with respect to the level of farm equipment. On the basis of zero unitarization method different variables are compared and used to form the synthetic variable. In consequence, three groups of districts were distinguished: of high, moderate and low level of farm equipment. This work is devoted to discussions on application of relative measures of accuracy of the ex-post forecasts. The authors showed that when the variable has a very large amplitude of seasonality indicators the average absolute forecast error (MAPE) can not be used. Theoretical study are illustrated on the example of thermal energy production. This work is devoted to discussions on application of relative measures of accuracy of the ex-post forecasts.

Decomposition of price time series was performed using method Census II/X11. Price of broiler chicken livestock characterize stable an stronger in recent years seasonality. In 2011 the seasonal index was ranged from 107,3% in August to 92,2% in December. In the range of six month more than half of price variability (51,4%) is a result of long period changes, 44,9% of variability is shaped by seasonal fluctuations and only 3,7% is made by irregulars fluctuations. In this paper, the rankings of the food industry sector companies listed on the Warsaw Stock Exchange were made on the basis of Taxonomic Attractiveness Measure of Investment. The following groups of variables were included in this study: liquidity ratios, profitability ratios, debt ratios, activity ratios, market-based ratios. Then analyzed whether the positions in the rankings of investigated companies remained stable over the period 2009-2011.

The article focuses on trade between Japan and Poland, in 2000-2010 years, using the SITC (Standard International Trade Classification), identifying trends occurring among one of classification group: Food and live animals. Analysis of exports and imports between Japan and Poland shows big changes in trade with Japan and the large growing difference in the trade balance. Furthermore the imported and exported groups of products show market differences and demand in Japan. The paper presented classification of voivodships due to the selected financial data business accommodation and catering department. For this purpose it was used the multidimensional statistical analysis allowing describe complex effect with help of one variable, so called value synthetic variable. Among the factors that impact the absorption of European Union funds in Polish agriculture, natural, demographic, technical and organisational conditions of the development of agriculture can be differentiated. The basic objective of the article is to identify and quantify the factors, which significantly impact the territorial differentiation of the absorption of European Union Funds in Polish agriculture within the framework of the “Modernisation of agricultural holdings” Rural Development Programme for 2007-2013.

The wage effects of student numbers on particular fields of study in Poland are analyzed. It is found that any of the fields of study, i.e. humanitarian, business and economics, technical or natural sciences, contributes to an increase in wages on the macroeconomic level, but the whole effect is smaller for studies in economics, which could be an outcome of too high interest in that kind of education. On the other side, our results for technical studies could be viewed as an argument in favor of an excess labor market demand for engineers compared to their supply by the educational system.

Opis:
Celem opracowania była próba delimitacji krajów w UE-27 o podobnej strukturze i skali pro-dukcji pochodzącej z gospodarstw rolnych. W badaniu położono nacisk na uwypuklenie po-dobieństwa struktur produkcji typowych dla obszarów klimatycznych UE-27 w 2008 roku, a także na wskazanie klasy, do której zakwalifikowano polskie rolnictwo. Wykorzystano dane z bazy FADN, którymi były średnie ważone przeliczone na gospodarstwo rolne z 27 krajów członkowskich UE w 2008 roku. Delimitację wykonano w oparciu o strukturę produkcji, wielkość ekonomiczną, powierzchnię użytków rolnych, wartość produkcji i dochodów z go-spodarstwa rolnego. Badanie wykonano za pomocą hierarchicznej klasyfikacji aglomeracyjnej metodą Warda. Przy czym strukturę produkcji reprezentowały 23 cechy, a pozostałe cechy były pojedyncze. Optymalną liczbę klas krajów o podobnej strukturze i skali produkcji wy-znaczono na podstawie analizy wielkości przyrostów wariancji wewnątrzklasowej w procesie łączenia klas między poszczególnymi poziomami łączeń. W ten sposób uzyskano 10 klas kra-jów. Klasy opisano według obliczonego miernika różnic średnich dla analizowanych cech.
The aim of the article was an attempt at delimitation of countries in the EU-27 with similar structure and scale of the production of farms. In this study, the emphasis is placed on high-lighting the similarity of production structures typical of the climate’s areas of the EU-27 in the year 2008, and also on indicating the class in which the Polish agriculture were classified. For this research, the data from FADN database was used. This database contains weighted averages per individual farm in every of 27 UE member countries in 2008. The delimitation were made based on the structure of production, economic size, agricultural utilized area, production and income of agricultural farm. The research was conducted using the agglomera-tion hierarchic classification based on the Ward’s method. The structure of production is rep-resented by 23 characteristics; the remaining characters are represented by single variables. The optimal number of classes of countries of similar structure and scale of production was estimated on the basis of the analysis of the amount of the intra-class variance’s increment. 10 classes of countries were obtained. These classes were described by the measure of the aver-age differences for analyzed characters.

Opis:
W opracowaniu przedstawiono typologię krajów Unii Europejskiej opartą na kryteriach dotyczących wartości eksportu w wybranych branżach usług oraz na ich udziale w całkowitej wartości usług eksportowanych z UE. Badanie wykonano z zastosowaniem metody analizy porównawczej, a grupy typologiczne krajów Unii Europejskiej wyodrębniono metodą Warda. Wskazano na wysokie obroty szczególnie w państwach wysoko rozwiniętych Europy Zachodniej oraz na dominujące znaczenie w strukturze zarówno eksportu, jak i importu usług, we wszystkich analizowanych branżach, Niemiec i Wielkiej Brytanii. Stwierdzono również, że nowe kraje członkowskie Unii Europejskiej z regionu Europy Środkowo-Wschodniej dotychczas w znaczącym stopniu nie wyspecjalizowały się w handlu usługami.
In her study, the author presented a typology of the European Union countries based on the criteria related to value of exports in the selected service industries and on their share in the total value of services exported from the EU. The research was carried out with application of the method of comparative analysis, while the typological groups of the European Union countries were selected by the Ward’s method. The author pointed out to high sales particularly in the highly developed states of Western Europe as well as to the prevailing importance in the structure of both exports and imports of services, in all the service industries in question, of Germany and the United Kingdom. She also ascertained that the new European Union Member States from the region of Central and Eastern Europe have so far not specialised to any significant degree in trade in services.
В разработке представили типологию стран-членов Европейского Союза, основанную на критериях, касающихся стоимости экспорта в избранных отраслях услуг, а также на их доле в совокупной стоимости услуг, экспортирумых из ЕС. Изучение провели, применяя метод сопоставительного анализа, а типологические группы стран-членов Европейского Союза выделили по методу Уорда. Указали высокий товарооборот в особенности в высокоразвитых странах Западной Европы, а также превалирующее значение в структуре как эскспорта, так и импорта услуг во всех анализируемых отраслях, Германии и Великобритании. Констатировали тоже, что новые страны-члены Европей- ского Союза из региона Центрально-Восточной Европы до сих пор в значительной степени не специализировались в торговле услугами.

Opis:
The diversity and multiplicity of information associated with investment in the stock market can cause problems with the proper understanding of the analyzed phenomena. In particular it refers to small investors who invest directly in stocks. Therefore, evaluating the financial condition of listed companies is very important, hence the need to use methods that will simplify and thus make stock market analysis easier. This paper presents an attempt to apply the selected financial ratios for the classification of 17 real estate companies listed on the Warsaw Stock Exchange into groups characterized by a similar economic condition. In the study multidimensional comparative analysis was used, i.e. Ward’s method and the method of k-means. The analysis was carried out in the period 2010-2012. In the experiment it was proved that using Ward’s method could identify companies with the weakest condition.

Opis:
Określono zmiany regionalnego zróżnicowania bilansu glebowej materii organicznej (MOG) na tle warunków siedliskowych i organizacyjno-ekonomicznych w województwie podkarpackim na przestrzeni lat 2002–2012. Podstawę analizy stanowiły dane Urzędu Statystycznego w Rzeszowie oraz informacje ze starostw powiatowych województwa podkarpackiego. Bilans materii organicznej gleby obliczono, wykorzystując współczynniki jej degradacji i reprodukcji. Uzyskane wyniki opracowano statystycznie, obliczając współczynniki trendu i zmienności oraz przeprowadzając analizę skupień Warda. Ogólny bilans glebowej materii organicznej w województwie podkarpackim w latach 2002–2012 był ujemny i wynosił średnio –0,19 t•ha-1, co powodowało konieczność przyorania słomy w ilości średnio 0,90 t s.m.•ha-1. Zmniejszenie obsady zwierząt z 0,44 DJP•ha-1 w 2002 r. do 0,26 DJP•ha-1 w 2012 r., dodatkowo ograniczyło dopływ do gleby materii organicznej z obornika. Spośród wydzielonych skupień najniższy stopień degradacji glebowej materii organicznej (–0,17 t•ha-1) oraz największą produkcję obornika – ponad 1,27 t s.m.•ha-1 – stwierdzono w powiatach położonych w środkowo-zachodniej części Podkarpacia. Powiaty należące do tego skupienia charakteryzują się największą w województwie obsadą zwierząt 0,51 DJP•ha-1i najniższą intensywnością organizacji produkcji roślinnej, wskutek ekstensywnej uprawy zbóż, zajmujących ponad 80% w strukturze zasiewów. Zdecydowanie ujemne wartości bilansu MOG (–0,45 t•ha-1) odnotowano w powiatach zlokalizowanych w środkowo-wschodniej części Podkarpacia. Duża intensywność organizacji produkcji roślinnej, głównie w powiatach łańcuckim, jarosławskim i przemyskim, z dominacją w strukturze zasiewów pszenicy ozimej, kukurydzy na ziarno oraz rzepaku ozimego, sprzyjała mineralizacji substancji organicznej i występowaniu ujemnego bilansu, dla zrównoważenia którego niezbędne było coroczne nawożenie słomą w ilości ponad 2,14 t•ha-1.
The aim of this study was to estimate changes in the regional differentiation of soil organic matter balance against a background of environmental, organizational and economic conditions in Podkarpackie Province. The analysis covered the years 2002–2012 and was based on data from Statistical Office in Rzeszów and from district authorities of Podkarpackie Province. The balance of soil organic matter was calculated using degradation and reproduction coefficients. The obtained results were subjected to statistical analysis, calculating trend and variability coefficients and using Ward’s cluster analysis. Total balance of soil organic matter in Podkarpackie Province in the years 2002–2012 was negative and amounted –0.19 t•ha-1 on average, which resulted in the necessity of ploughing straw in the average amount of 0.90 t DM•ha-1. Reducing livestock density from 0.44 in 2002 to 0.26 LU•ha-1 in 2012 additionally limited the supply of organic matter from farmyard manure to soil. From among the distinguished clusters, the lowest degree of degradation of soil organic matter (–0.17 t•ha-1) and the highest manure production of over 1.27 t DM•ha-1 was found in districts located in the central-western part of Podkarpacie. Localities belonging to this cluster were characterised by the highest animal stock of 0.51 LU•ha-1 and by the lowest intensity of organization of crop production as a result of extensive cultivation of cereals that covered more than 80% in the crop structure. Definitely negative values of soil organic matter balance (–0.45 t•ha-1) were recorded in districts located in the central-eastern part of Podkarpacie. High intensity of crop production organization, mainly in the Łańcut, Jarosław and Przemyśl districts, with predominance of winter wheat, maize for grain and winter oilseed rape in their structure of cropland, favoured mineralization of organic substance and the occurrence of negative balance, which requires annual fertilisation with straw in the amount of more than 2.14 t•ha-1 to achieve the balance.

W opracowaniu zaprezentowano podstawowe wskaźniki obrazujące poziom nakładów na działalność B+R oraz strukturę ich finansowania w Polsce na tle krajów Unii Europejskiej. Dokonano oceny zróżnicowania poziomu oraz zmian trendów działalności B+R i innowacyjności w ujęciu województw Polski w latach 2005-2011 z wykorzystaniem wskaźników indywidualnych, a także dwóch metod taksonomicznych: metody TOPSIS i metody Warda. Otrzymane wyniki potwierdziły to, że województwo mazowieckie jest liderem we wszystkich rankingach i regionem zdecydowanie wyróżniającym się wśród pozostałych województw. Dla większości regionów Polski zaobserwowano zróżnicowanie zajmowanej pozycji w rankingu, jak również zmianę przynależności tych województw do różnych skupisk w badanych latach.
In the paper basic indicators depicting/describing the level of the expenditures on R&D activity and the structure financing them in Poland against the background of EU countries are presented. An assessment of diversifying the level and changes of trends in R&D activity and innovativeness in voivodships in Poland during the period 2005-2011 by making use of individual indicators as well as two taxonomical methods: TOPSiS and Ward’s methods has been done. Received results confirm that mazowieckie voivodship is the leader in all rankings and firmly comes the other provinces off. For the majority of regions in Poland diversifying the filled position in the ranking, as well as the change of the membership of these provinces in different clusters in examined years were observed.

Celem artykułu jest prezentacja wykorzystania wielowymiarowej analizy korespondencji do badania podróży turystycznych turystów polskich i niemieckich związanych z odwiedzinami Wolińskiego Parku Narodowego. Podjęto próbę wykrycia powiązań pomiędzy zmiennymi charakteryzującymi te podróże. Do obliczeń wykorzystano moduł Analiza korespondencji w pakiecie Statistica 10.0. W celu podwyższenia jakości odwzorowania przeprowadzono modyfikację wartości własnych według propozycji Greenacre’a. Ze względu na dość dużą liczbę wariantów analizowanych zmiennych zastosowano metodę Warda, która umożliwiła wyznaczenie powiązań pomiędzy wariantami zmiennych. Dodatkowo, dane zostały zobrazowane za pomocą metody twarzy Chernoffa, która umożliwiła zaprezentowanie różnic pomiędzy profilem preferencji statystycznego turysty niemieckiego i polskiego odwiedzającego Woliński Park Narodowy.
There is still a small contribution of German tourists visiting Polish natural protection areas at Polish- German borderlands despite the border checks elimination in 2007. An example of protected areas in Poland located at the borderland is the Wolin National Park (WNP); the share of foreign visitors of the park including Germans, is still marginal (approx. 0.7%). The paper is aimed at presentation of the possibilities of using multiple correspondence analysis to study Polish and German tourists visiting WPN. At fi rst the travel preferences have been illustrated by the method of Chernoff faces. The specific objective of the research was to investigate relationship between variables characterizing German and Polish tourists. Also Ward’s method was applied because of the relatively large number of analyzed variable variants; it allowed indicating the links between the variants. The latter revealed 3 groups of tourists visiting WPN; two of them distinguished different nationalities. The calculations and graphical presentations of the results have been computed with Statistica software version 10.0.

Celem rozważań było określenie podobieństw i różnic między gospodarstwami mlecznymi z poszczególnych regionów Unii Europejskiej w latach 2007-2011. Zróżnicowanie gospodarstw mlecznych w regionach określono za pomocą aglomeracyjnej analizy skupień metodą Warda, na podstawie danych FADN. Analizie poddano siłę ekonomiczną gospodarstw ESU, powierzchnię wykorzystywanych gruntów ornych, ilość krów mlecznych oraz średnią roczną mleczność krów. Na tej podstawie dokonano typologii regionów UE. W wyniku przeprowadzonego grupowania uzyskano pięć jednorodnych skupień regionów. Porównano wskaźniki produkcyjne i ekonomiczne w poszczególnych grupach regionów w celu określenia podobieństw i różnic między skupieniami.
The purpose of the considerations was to identify similarities and differences between dairy farms from different regions of the European Union in 2009. The diversity of dairy farms in the regions of theEuropean Union was determined by agglomerated cluster analysis using Ward's method. The research was based on FADN data. It analyzed the economic size of farms (ESU classification), total utilised agricultural area, the number of dairy cows and the average annual milk yield. On this basis the typology of EU regions has been made. As a result of clustering five homogeneous cluster regions have been obtained. A comparison of production and economic indicators in each group of regions has been made to determine the similarities and differences between the clusters.
Целью рассуждений в этой статье было определение сходств и различий между молочными хозяйствами в отдельных регионах Европейского Союза в 2007-2011 годах. Дифференциация молочных хозяйств в регионах определялась с помощью агломерационного анализа концентрации производства методом Варда на основании данных FADN. Был проведен анализ экономической мощи хозяйств ЕС, площадь использованных пахотных почв, количество молочных коров, а также среднюю годовую молочность коров. На этом основании была проведена типология регионов ЕС. В результате проведенной группировки было получено пять однородных регионов аграрного состояния продукции. Было проведено сравнение производственных и экономических показателей в отдельных группах регионов для определения сходств и разниц между аграрным состоянием продукции.

Opis:
Celem artykułu jest identyfikacja i charakterystyka wzorców konsumpcji żywności w Polsce. Gospodarstwa domowe w Polsce są bardzo zróżnicowane pod względem poziomu i struktury spożycia żywności. Wynika to zarówno z czynników ekonomicznych, jak i pozaekonomicznych. Znaczący wpływ na kształtowanie wzorców konsumpcji żywności mają także zalecenia żywieniowe prowadzące do racjonalnego (prozdrowotnego) żywienia. Narzędziem umożliwiającym identyfikację wzorców konsumpcji żywności są metody taksonomiczne, w tym analiza skupień. W badaniu uwzględniono siedem grup społeczno‑ekonomicznych gospodarstw domowych w Polsce, tj. cztery zlokalizowane na obszarach wiejskich: pracownicy, rolnicy, osoby pracujące na własny rachunek, emeryci i renciści oraz trzy zlokalizowane w mieście: pracownicy, osoby pracujące na własny rachunek oraz emeryci i renciści. Grupowanie wiejskich i miejskich gospodarstw domowych według wzorców konsumpcji żywności przeprowadzono hierarchiczną aglomeracyjną metodą Warda. Każdą grupę ludności scharakteryzowano za pomocą trzydziestu dwóch zmiennych diagnostycznych. Na podstawie przeprowadzonego badania wyodrębniono cztery skupienia i dwa różne wzorce konsumpcji żywności: miejski wzorzec konsumpcji żywności oraz wiejski wzorzec konsumpcji żywności.
The aim of the article is to identify and characterize the patterns of food consumption in Poland. The Author analyses food consumption in Poland on the basis of CSO’s household budget surveys. Households in Poland are very diversi fied in their level and structure of food consumption. This results from both economic and non-economic factors. Significant impact on the shaping of food consumption patterns has been observed in the case of dietary recommendations promoting rational (healthy) nutrition. Taxonomic methods, including cluster analysis serve as a main tool, which allows the identification of food consumption patterns. The study included seven socio-economic groups of households in Poland, i.e. four located in rural areas: employees, farmers, the self-employed, retirees and pensioners and three located in city: employees, the self-employed, and retirees and pensioners. Grouping of urban and rural households according to food consumption patterns was carried out using Ward’s hierarchical agglomeration method. Each population group was characterized by 32 diagnostic variables. As a result of this grouping, four clusters were identified. Each of these clusters was characterized by a different level and structure of food consumption, while the households belonging to the same cluster had a similar food consumption profile. In those four clusters two different food consumption patterns were identified: urban pattern of food consumption and rural pattern of food consumption.
