Opis:
This paper evaluates the spatial diversity of the quality of life of residents in selected rural-urban and rural communities of the Świętokrzyskie province in 2010 and 2015. The investigation addressed the following five areas of research: material living conditions, economic activity, quality of educational and cultural offerings, quality of general healthcare, and protection of the natural environment. A set of twenty-two diagnostic variables was selected as part of the previously mentioned components. Hellwig's taxonomic method served to measure the quality of life and to order the communities regarding standards of the local populations' quality of life. The results were then subjected to Ward's agglomerative method of grouping, which helped to distinguish similar units. The application of a synthetic measure allowed for an effective measurement of the phenomenon. The analysis helped to identify groups of communities with the highest, high, low, and lowest standards of quality of life.
Jakość życia jest pojęciem o charakterze wielowymiarowym, co przekłada się na trudności w pomiarze tej kategorii ekonomicznej. Mimo to jest przedmiotem zainteresowań wielu dyscyplin naukowych. Celem artykułu jest ocena porównawcza przestrzennego zróżnicowania jakości życia mieszkańców w wybranych gminach miejsko-wiejskich i wiejskich województwa świętokrzyskiego w latach 2010 i 2015. Ocena została przeprowadzona z uwzględnieniem pięciu obszarów badawczych W ramach wyróżnionych składowych wyselekcjonowano zbiór dwudziestu dwóch zmiennych diagnostycznych. Do pomiaru poziomu jakości życia zastosowano taksonomiczną metodę Z. Hellwiga, która pozwoliła uporządkować gminy ze względu na poziom jakości życia społeczności lokalnych. Uzupełnienie wyników badań stanowi aglomeracyjna metoda grupowania Warda, która umożliwiła wyodrębnienie podobnych do siebie jednostek. Przeprowadzona analiza pozwoliła zidentyfikować grupy gmin o najwyższym, wysokim, niskim i najniższym poziomie jakości życia.

Opis:
Green growth is a new approach to the economy that assumes the efficient use of raw materials while minimizing the negative impact on the environment. The aim of the study is to assess green growth in the European Union countries in 2019. For this purpose, secondary data was used and a multidimensional analysis of sustainable development was performed. The non-pattern model together with the Hellwig and Ward methods were implemented. This enabled a comparison between countries, and their classification due to a similar level of development. Based on the analysis, a large discrepancy in terms of green growth was observed in the examined countries. It was noted that the disproportion may turn out to be a problem in the implementation of the sustainable development policy. The results also showed that the position of the country is reflected in its geographic location.

Celem pracy jest rozstrzygnięcie, czy metoda Hellwiga jest użyteczna w odniesieniu do konstruowania modeli szeregów czasowych i w jakim zakresie jest ona konkurencyjna wobec innych metod, na przykład wykorzystujących kryteria informacyjne Schwarza i Akaike. Okazuje się, że metoda Hellwiga w pewnych, często w praktyce ekonometrycznej występujących przypadkach, nie prowadzi do wyboru odpowiedniego modelu.
We check if Hellwig method is useful in building time-series models and if it performs better than other statistical methods, including Akaike and Schwarz information criteria. We find that the Hellwig method often leads to incorrect model specifications.

Celem opracowania jest analiza poziomu wdrażania zrównoważonego rozwoju w podregionach pięciu województw Polski Wschodniej. W opracowaniu wykorzystano podstawowe narzędzia monitoringu tejże koncepcji, którymi są wskaźniki zrównoważonego rozwoju pogrupowane według obszarów: społecznego, gospodarczego i środowiskowego. Efektem jest opracowanie rankingu podregionów Polski Wschodniej w roku 2013 wraz z wyszczególnieniem rankingów podregionów w poszczególnych obszarach zrównoważonego rozwoju. Analiza ma charakter ilościowy i jakościowy. Do jej przeprowadzenia wykorzystano dane dotyczące z poziomu NTS3 za rok 2013, pozyskane z Banku Danych Lokalnych GUS. Z grupy 97 wskaźników wybrano 34, które są istotne z punktu widzenia tematu badania. Do przeprowadzenia porządkowania liniowego podregionów województw Polski Wschodniej w aspekcie wybranych wskaźników została użyta – ze względu na wielokryterialność badania – metoda wzorcowa Hellwiga. Praca zawiera również analizę wybranych wskaźników mających wpływ na miejsce podregionów w rankingu.
The aim of the paper is to analyse the level of implementation of sustainable development in the subregions of the five voivodeships of Eastern Poland. The author uses basic tools for the monitoring of this concept of development, i.e. indicators of sustainable development grouped according to social, economic, and environmental areas. The result is the creation of a ranked list of the subregions of Eastern Poland in 2013, along with the ranking lists of subregions in specific areas of sustainable development. The analysis has both a quantitative and qualitative aspect. To conduct the study, data for NTS3 level from the Local Data Bank, a database of the Central Statistical Office of Poland for the year 2013 were used. Out of the total number of 97 indicators, 34 were selected as relevant. Because of the multi-criteria nature of the research, in order to perform the linear ordering of the subregions of Eastern Poland in terms of the chosen indicators, the Hellwig method was used. The paper also contains an analysis of selected indicators affecting the subregions' positions on the ranked list.

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.

Theoretical study are illustrated on the example of thermal energy production. The analysis of monthly prices of broiler chicken livestock in years 1991 - 2011 in this paper was presented. 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:
Research background: The choice of the issue of international competitive-ness of economies as the research problem addressed in this paper has been mainly dictated by the changes observed in the nature of the development of EU economies and the need to assess the competitiveness of the Polish economy. It is time to evaluate and learn from the largest enlargement in the history of the EU which took place in May 2004. An assessment of changes in the state of EU economies, including the Polish economy, is in the centre of research interest of many scientists. National competitiveness is the subject of a great deal of research and economic studies. Integration and globalisation processes in the world economy are the main reasons for the popularity of this topic. The efficient use of sources and factors determining the competitiveness of economies, sectors and enterprises is associated with prosperity over the long term. One of the methods based on the observation of selected basic indicators of economic competitiveness is the method of analysis called the macroeconomic stabilisation pentagon. The method illustrates the extent to which the government achieves five macroeconomic objectives. It is very difficult, if not impossible, to meet all these objectives at the same time. The difficulty of meeting all these goals concurrently is due to the fact that they are more or less competitive rather than complementary. The proposed assessment of competitiveness based on the developed model of macroeconomic stabilisation pentagon is a unique approach in terms of discussion of country's competitiveness. This approach significantly distinguishes the current study in comparison with standard international reports on competitiveness such as the Global Competitiveness Index or the EU Regional Competitiveness Index. Purpose of the article: The main aim of the paper is to assess the competitiveness of EU economies in the years 2005-2018, based on a selected set of diagnostic variables referring to the concept of macroeconomic stabilisation pentagon. The paper also formulates a detailed list of four research hypotheses. Methods: In order to characterise the competitiveness of the European Union economies, including the EU-15 and EU-13 groups, as well as the Visegrad group, six diagnostic variables affecting the economic situation of individual EU countries were analysed. The variables for analysis were chosen so as to reliably describe the competitive position of a given country, at the same time referring in a substantive sense to the concept of macroeconomic stabilisation pentagon. The linear ordering of objects was made using the reference Hellwig method. The selected method enabled the development of competitiveness rankings of EU Member States in the years 2005, 2009, and 2018. Findings & Value added: The comparative analysis of the main macroeconomic indicators conducted in the paper forms the basis for assessing the current state of the EU economy in relation to other countries. In the paper, the authors depart from the standard elaboration of 'magic pentagon.' Instead, they apply the variables used in the macroeconomic stabilisation pentagon analysis to develop competitiveness rankings of EU Member States. The con-ducted empirical study has confirmed that the 15th anniversary of EU member-ship had a decidedly positive impact on the level of economic development of the EU-13 countries.

Opis:
E-commerce in Europe is becoming increasingly important in all market segments, and in most segments it already accounts for few or even several dozen percent of total trade. According to a report by E-commerce Europe, it has already left the US market behind in 2010. Year by year, the willingness to buy products, which until recently were not treated by many consumers as “online”, such as food products, is growing. Considering the above, the aim of the article is to determine the level of development of e-commerce in the European Union (EU-28). In the research procedure the literature and EUROSTAT data were used. The following research methods were used for data analysis: literature analysis, the Hellwig’s method and the threshold grouping method. The analysis was carried out in two periods, i.e. in 2014 and 2018, which allowed assessing the direction of changes in the surveyed.
Handel internetowy w Europie ma coraz większe znaczenie we wszystkich segmentach rynku, a w większości segmentów stanowi już od kilku do nawet kilkudziesięciu procent przypadający na cały handel. Według raportu stowarzyszenia E-commerce Europe, już w 2010 roku zdystansował on rynek USA. Z roku na rok rośnie skłonność do zakupu produktów, które do niedawna nie były traktowane przez wielu konsumentów za „internetowe” jak np. produkty spożywcze. Celem artykułu jest określenie poziomu rozwoju handlu internetowego w krajach Unii Europejskiej (UE-28). W postępowaniu badawczym wykorzystano literaturę dotycząca badanej problematyki oraz dane EUROSTAT. Do analizy danych wykorzystano następujące metody badawcze: analizę literatury, metodę Hellwiga oraz progową metodę grupowania. Analiz dokonano w dwóch okresach, tj. w roku 2014 oraz 2018, co pozwoliło na ocenę kierunku zmian w badanych.

Opis:
Research background: Quality of life is viewed as the degree of people's satisfaction of various needs, especially including material, spiritual, safety-related needs and life aspirations. The aspects taken into consideration are economic, spatial, environmental and cultural ones. Quality of life is therefore determined by various conditions in which a human lives and the source of which is the hierarchy of needs and a value system. At the same time, quality of life can be viewed in terms of collectivity (objective aspect) and an individual's evaluation (subjective aspect). The former view shapes the existing living conditions and the latter results from the satisfaction from a specific person's life, experiences and ambitions. The multidimensionality of the quality of life categories translates into difficulties in defining and measuring it, and constitutes an interesting research object. Purpose of the article: The purpose of the article is to diagnose and evaluate the variety of the quality of life in Polish voivodeships, in objective terms by building a synthetic measure allowing for estimating inequalities in the quality of life of regional communities. It was assumed that quality of life will be characterised by indicators grouped into the following areas: material living conditions, economic activity, health, education and living environment quality. Methods: The main method used for measuring quality of life is the linear ordering based on Z. Hellwig's taxonomic measure which allows for organising voivodeships in terms of the quality of life of communities. Additionally, the cluster analysis (Ward's agglomerative grouping method) was used, which allowed for distinguishing voivodeships similar in terms of the analysed phenomenon. Findings & Value added: During the realisation of the research goal, special attention was paid to the complexity of the quality of life issue and its measurement in terms of economy and rather important varieties in voivodeships were emphasized. The conducted analysis allowed for distinguishing groups of regions with the highest, high, low and the lowest quality of life.

Research background: Social and economic development involves a broad spectrum of social, economic and spatial phenomena. The multi-faceted nature of regional development arises directly from the fact that it is shaped by multiple factors. Current discourse emphasises the role of endogenous factors, which indicate the specific nature and the distinctive features of the given territory. Mobilising the endogenous potential ensures stable regional development dynamics. At the moment, one of the fundamental economic problems are the increasing differences in the development of specific regions. Purpose of the article: The purpose of this study is to assess the differentiation of the social and economic level development of Polish Voivodeships, applying the selected assessment methods for the years 2010 and 2015, draw up a rank list of regional units according to their development levels, and identify the groups of Voivodeships sharing similar development levels. The indicators used in this study, characterising the level of the social and economic development, have been systematised according to the following areas: demographics and labour market, regional entrepreneurship, local economy structure, innovation and research & development activities, technical infrastructure, social infrastructure, and the condition and protection of the natural environment. Methods: The level of the social and economic development of Polish Voivodeships was assessed using Zdzisław Hellwig's development pattern method, which made it possible to rank them according to the level of development of Polish Voivodeship. The methodology is supplemented by Ward's agglomerative clustering method, which made it possible to distinguish other Voivodeships according to the analysed phenomenon. The Voivodeship clustering method used Jenks' natural breaks classification method. Findings & Value added: Pursuing the research aims, the authors focused in particular on clear spatial differences. Through the analysis we were able to identify the changes in the social and economic development processes of the Polish regions. The Voivodeships were divided into groups according to their development level: the highest, high, low and the lowest.

Celem artykułu jest dokonanie pomiaru poziomu życia w powiatach województwa lubuskiego i pogrupowanie powiatów ze względu na to kryterium. Analizy przeprowadzono dla danych z 2017 r. pozyskanych z Urzędu Statystycznego w Zielonej Górze oraz Banku Danych Lokalnych Głównego Urzędu Statystycznego. W badaniu wykorzystano wybrane wskaźniki charakteryzujące poziom życia w 10 obszarach, które dotyczą warunków funkcjonowania społeczności lubuskich powiatów. Poziom życia zmierzono z wykorzystaniem syntetycznej miary taksonomicznej zaproponowanej przez Hellwiga. Wskazano, że główne czynniki cechujące grupy powiatów wyróżnione na podstawie zastosowanej miary mają charakter ekonomiczny. Wyjątek stanowią miasta na prawach powiatu, w przypadku których większe jest znaczenie czynników infrastrukturalnych, środowiskowych i społecznych.
The aim of the paper is to measure the standard of living in the powiats of Lubuskie voivodship and to group them according to this criterion. The analyses were carried out for the data from 2017 obtained from the Statistical Office in Zielona Góra and the Local Data Bank of Statistics Poland. The author used selected indicators describing the standard of living in 10 areas that determine the living conditions of communities in the Lubuskie powiats. The standard of living was measured using Hellwig’s synthetic taxonomic measure. The study demonstrated that what distinguished the groups of powiats (extracted by the measure) to the largest extent, were economic factors. However, cities with powiat status, where infrastructural, environmental and social factors were more important, proved an exception to this rule.

Opis:
The growing significance of the real estate market prompts investors to search for factors and variables which support cohesive analyses of real estate markets, market comparisons based on diverse criteria and determination of market potential. The specificity of the real estate market is determined by the unique attributes of property. The Authors assume that developing real estate market ratings identifies the types of information and factors which affect decision-making on real estate markets. The main objective of real estate market ratings is to create a universal and standardized classification system for evaluating the real estate market. One of the most important problems in this area is collecting appropriate features of real estate market and development dataset. The main problem involves the selection and application of appropriate features, which would be relevant to the specificity of information related to the real estate market and create a kind of coherent system aiding the decision-making process. The main aim of this study is the optimization of set of variables that were used to develop the real estate market ratings. For this purpose, Hellwig’s method of integral capacity of information was applied. In this particular case, the method shows what set of variables provides information most sufficiently. The results lead to obtaining the necessary set of features that constitute essential information which describes the situation on the local real estate market.
