This paper assesses EU countries in terms of their level of renewable energy use. The ranking of 27 EU countries in terms of the complex phenomenon under study was constructed on the basis of 7 variables. The research period was 2011 and 2020. The research method was one of multi-dimensional comparative analysis methods, i.e. Hellwig’s pattern development model. The research results confirm that there wasa positive change in the use of renewable energy in all EU countries in 2020 compared to 2011, with Sweden, Austria, Finland, and Denmark taking the lead. However, most EU countries (16 in 2011 and 17 in 2020) have a medium-low level of use of “green energy”. A low level was identified in Cyprus and Malta in 2011 and Poland in 2020.

W pracy oceniono kraje UE pod względem poziomu wykorzystania energii odnawialnej. Podstawę budowy rankingu 27 krajów UE pod względem badanego zjawiska złożonego stano-wiło 7 zmiennych, a okresem badawczym był 2011 i 2020 rok. Zastosowaną metodą badawczą była jedna z metod wielowymiarowej analizy porównawczej – metoda wzorca rozwoju Z. Hellwiga. Wyniki przeprowadzonych badań potwierdzają, że w 2020 w porównaniu do 2011 roku we wszystkich krajach UE nastąpiły pozytywne zmiany w zakresie wykorzystania energii odnawialnej. Liderami są Szwecja, Austria, Finlandia i Dania. Większość krajów UE (w 2011 roku – 16; w 2020 roku – 17) posiada jednak średnioniski poziom wykorzystania tzw. „zielonej energii”. Natomiast poziom niski uzyskały w 2011 roku Cypr i Malta, a w 2020 roku – Polska.

There are more and more new development challenges emerging in Polish cities and regions recently. Because of those challenges we can observe an increase of the role of cities and associated environments. The concept of cities’ impact on the environment is a result of many processes, such as: suburbanization, reurbanization, increasing population mobility, development of transport systems, innovation, or entrepreneurship. A city is a complex entity, it is a subject to dynamic changes, to understand which we need interdisciplinary knowledge or the combination of many different approaches along with an attempt to draw many conclusions. We can find numerous theoretical examples describing city-regional environment relations in the literature. In general, these models explain the relationship between economically strong cities (metropolis) and the regions. However, there is not much literature and research explaining the nature and strength of relationships with medium-sized cities. There are also very few ideas for developing the potential of medium-sized cities in polish national policy. The aim of the article is to present disproportions in the development of medium-sized cities in voivodships of Eastern Poland in 2010-2017. The author will also present the possibility of using a synthetic measure to assess and recognize the spatial diversity of medium-sized cities development.

The purpose of this article is to assess the investment activity (investing activities) of companies in Poland depending on the industry they belong to. The first part of the study presents theoretical issues concerning business investments. The second part presents a comparative study of the investment activity of Polish companies operating in various industries. In this study, in order to assess the investment activity of companies in Poland based on the industry they belong to, two selected methods of linear ordering (the method of sums and Hellwig‘s method) were used, both falling within the scope of a multidimensional comparative analysis. In the analyzed period, the majority of examined industries showed high fluctuations in their investment activity, which is likely due to the uncertainty faced by Polish companies. Industries showing the highest level of investment activity in 2010-2016 in both methods are: industrial sector, administration and support activities, transportation and warehousing, real estate services. Industries showing the lowest level of investment activity are: education, trade and repair of motor vehicles.

Celem artykułu jest ocena aktywności inwestycyjnej przedsiębiorstw w Polsce w ujęciu branżowym. W pierwszej części opracowania przedstawiono zagadnienia teoretyczne dotyczące inwestycji przedsiębiorstw. W drugiej zaś przedstawiono badanie porównawcze aktywności inwestycyjnej przedsiębiorstw w Polsce działających w różnych branżach. W prezentowanym badaniu, w celu oceny aktywności inwestycyjnej przedsiębiorstw w Polsce w ujęciu branżowym zastosowano dwie wybrane metody porządkowania liniowego (metodę sum oraz metodę Hellwiga), które mieszczą się w obrębie wielowymiarowej analizy porównawczej. W analizowanym okresie w większości badanych branż aktywność inwestycyjna wykazywała się wysokimi fluktuacjami, co jest prawdopodobnie wynikiem niepewności, z jaką zmagają się polskie firmy. Branże charakteryzujące się najwyższym poziomem aktywności inwestycyjnej w latach 2010-2016 w obu zastosowanych metodach to: przemysł, administrowanie i działalność wspierająca, transport i gospodarka magazynowa, obsługa rynku nieruchomości. Branże charakteryzujące się najniższym poziomem aktywności innowacyjnej to: edukacja, handel i naprawa pojazdów samochodowych.

Urban transport is considered the basis of properly functioning cities and their development. The main aim of the paper is to attempt the assessment of urban transport development in selected voivodeships (provinces) as a crucial factor of macro logistics. The research also aimed to identify the underdeveloped areas of urban transport in Poland as the basis for the implementation of support policy. The source of information in the investigation process was data drawn from the Central Statistical Office in Poland for 2013–2016. In the scope of dealing with the research problem, chosen classical and order multivariate statistical measures were implemented into the research process. Next, the taxonomic measures for the years of interest served as the basis for the construction of the total (general) synthetic measure applicable to the entire period. The main results and findings of the research indicate that the level of urban transport development is correlated with the whole transportation system which affects the socio-economic development of some regions of Poland. The research can lead to a better understanding of Polish urban transportation development in selected regions. Hence, the results can be helpful in the investment process and for shaping the right transportation policy to improve the use of financial resources.

The aim of the research was to identify the level of the Polish municipality’s own investment capacity with the most significant share of naturally valuable areas in the years 2014-2016 and the level of tourism development of these areas. The methods of economic analysis – comparative, indicative and tools of taxonomic analysis were used here, which allowed for ranking of the surveyed units in terms of the level of naturally valuable, tourism function, the level of local development and own investment potential. The surveyed entities had their own investment capacity, however, due to the scope of infrastructure needs, it should be assessed as low. The conducted research indicates a small scope of development of tourism in communes with the with the highest naturally valuable areas. In results, it can be concluded that this development opportunity has not been effectively used. In the authors’ opinion, the development of the tourist function in the most naturally valuable areas which ensures that tourism will be the basis of local development of these areas is not possible without external support in the form of subsidies from the national budget and the implementation of knowledge on how to manage these areas.

Transport is considered one of the basic aspects of the movement of people, raw materials as well as goods from the place of origin to the destination. Moreover, in the wider sense, transport includes economic bodies that aim to achieve goals similar to those of businesses that produce a wide range of goods required by customers. Hence, the efficient operations of basic branches of the transportation system determine the entire national economy. Furthermore, transport is considered a basic factor of development, both on the macro- and microeconomic scales. The aim of the paper is to attempt the assessment of the road transport in Poland as an important element of macro logistics. Furthermore, one of the aims of the investigation was the explanation of its influence on the level of economic development in Poland. As the source of information, the research used the data drawn from the Central Statistical Office of Poland. The main methods implemented in this study were both classic and order synthetic measure construction. Further, these measures were used in econometric models as well as for the prediction of their values. The main result of the analysis indicates that the development level of the widely considered infrastructure is strictly correlated with the socio-economic development of particular voivodships. The study on the level of road transport development can lead to a better understanding of the socio-economic development of particular areas of Poland as well as the more efficient use of the support funds.

Transport is considered a basis for socio-economic development. It is closely connected with the process of movement of products and humans. The main aim of the paper is to investigate the influence of different order normalization methods in the synthetic measure construction implemented in the assessment of the development of European Union member states in the area of logistic, especially transportation system. Moreover, the article attempts to investigate the influence of such methods on linear ordering in multi-criteria taxonomic approach. The source of information in the research is the data drawn from Eurostat, the statistical office of the European Union. The main method in this study is the order synthetic measure constructed with Weber median in different forms due to implemented normalization methods. The main result of the carried out analysis indicated that the development level of three main branches of a transportation system correlates with the socio-economic development of particular member states. Furthermore, the assessment process based on the synthetic measure construction can lead to differences in linear ordering due to the implemented normalization methods. The research on the transport development can bring a better understanding of the socio-economic development of particular areas of the European Union. Hence, the results can be helpful to European policy makers for the allocation of support funds.
