Abstrakt	Wdrażanie rozwiązań z zakresu biogospodarki cyrkularnej jest zagadnieniem złożonym. Wymaga to dobrej znajomości koncepcji, różnych procesów gospodarki o obiegu zamkniętym i ich oczekiwanych skutków dla sektorów oraz łańcuchów wartości. Jednak badania nad gospodarką o obiegu zamkniętym wydają się być fragmentaryczne w różnych dyscyplinach i często istnieją różne perspektywy interpretacji tego pojęcia i powiązanych aspektów, które należy ocenić. Niniejszy artykuł zawiera przegląd literatury na temat biogospodarki i gospodarki o obiegu zamkniętym w celu lepszego zrozumienia tej koncepcji, a także jej różnych wymiarów i oczekiwanych skutków. Celem artykułu jest zarysowanie koncepcji biogospodarki o obiegu zamkniętym wraz z przedstawieniem głównych uwarunkowań jej wdrażania. Przedstawiono wybrane inicjatywy polityczne na rzecz wdrażania koncepcji gospodarki o obiegu zamkniętym w sektorze biogospodarki oraz modele biznesowe dedykowane dla rozwiązań biogospodarczych.
Abstract	Implementing circular bioeconomy solutions is a complex issue. It requires a good knowledge of the concepts, the different processes of the circular economy and their expected impacts on sectors and value chains. However, research on the circular economy appears to be fragmented across disciplines and there are often different perspectives on the interpretation of the concept and related aspects to be assessed. This article reviews the literature on bioeconomy and closed-loop economy to better understand the concept, as well as its different dimensions and expected impacts. The aim of the article is to outline the concept of a circular bioeconomy along with a presentation of the main considerations for its implementation. Selected policy initiatives for the implementation of the closed-loop bioeconomy concept in the bioeconomy sector and business models dedicated to bioeconomy solutions are presented.

Tytuł	New Approaches to Developing the Integral Indicator Methodology for Estimating the Financial Efficiency of Agricultural Entities in Poland, the Republic of Moldova, and EU Countries
Title	New Approaches to Developing the Integral Indicator Methodology for Estimating the Financial Efficiency of Agricultural Entities in Poland, the Republic of Moldova, and EU Countries
Słowa kluczowe	agro-sector, European Union, correlation and regression, financial efficiency, food product, financial economy, productivity & profitability, resource efficiency
Key words	agro-sector, European Union, correlation and regression, financial efficiency, food product, financial economy, productivity & profitability, resource efficiency
Abstrakt	Economic literature pays a great deal of attention to economic and financial efficiency, expressed in terms of competition, concentration, productivity and profitability. This paper provides an all-embracing framework for the various existing theories in this area and illustrates these theories with practical applications. Currently, changing the size of the production potential in agricultural units in the Republic of Moldova depends to a great extent on the influence of different trends in the modification of production resources: the reduction of labor resources and agricultural land, quantitative and qualitative changes in fixed assets, and in current assets, etc.The notion of resource potential means the totality of the volume of all resources (natural, labor, material, intellectual, information, etc.) on specific enterprises, territories, branches, regions. Evaluating a broad field of research, the paper describes profit maximizing food products and demonstrates how several widely-used products can be fit into this framework. The authors also present an overview of the current major trends in the food sector and relate them to the assumptions for food products, thereby displaying their relevance and timeliness. The results include a set of recommendations for future research on this topic.The design, methodology and approach of this research is to explain why efficiency can help obtain a profit surplus, and to measure this efficiency. For quality of methodology we apply a range of statistical methods, as well as the strategic capability of organisations – made up of resources and competences. One way to approach the stategic capability of an organisation is to consider its strengths and weaknesses (for example, where it has a competitive advantage, profit, efficiency or disadvantage). Based on our research and results, we sought to understand the concepts of financial effciency and to apply these concepts to practical situations. At the start of each analysis entrepreneurship plays an important role. Most organisations have to innovate constantly to obtain profit and efficiency for food products. They need to be first into a market, or simply a follower of customers in developing new products and services. Original studies in Moldova and Poland regarding farm concentration in terms of Gini Coefficient, Gini Index and Concentration Index of the utilized agricultural area. Original calculus formula to determine the Concentration Index of the UAA for the top 10% largest farms in Moldova and UK.

Tytuł	Prawa własności dóbr oraz ich implikacje dla transferu ziemi rolnej
Title	Property rights of goods and their implications for agricultural land transfer
Słowa kluczowe	ziemia rolna, prawa własności, rynkowy transfer ziemi, nierynkowy transfer ziemi
Key words	agricultural land, property rights, market land transfer, non-market land transfer
Abstrakt	Celem prowadzonych badań było określenie relacji pomiędzy rynkowym a nierynkowym transferem praw własności ziemi rolnej. Badania przeprowadzono w nawiązaniu do drugiego twierdzenia teorii dobrobytu, z którego wynika, że każdą efektywną alokację w rozumieniu Pareto można osiągnąć w wyniku działania zdecentralizowanego mechanizmu rynkowego. Ponadto podjęto próbę udzielenia odpowiedzi na pytanie: jak istniejący system praw własności oddziałuje na skalę rynkowej alokacji zasobów ziemi. Na podstawie uzyskanych wyników stwierdzono, że istnieją możliwości dalszego rozwoju rynku ziemi oraz występują przesłanki stopniowej poprawy efektywności alokacji ziemi w Polsce.
Abstract	The aim of the research was to determine the relationship between market and non-market transfer of property rights of agricultural land. This analysis was carried out due to the second proposition of the theory of well-being, from which it follows that every effective allocation in the Pareto sense can be achieved as a result of the decentralized market mechanism. In addition, an attempt was made to answer the question: if, and if so, how, the existing system of property rights limits the scale of the market allocation of land resources. The research also assessed the state's interference in the process of land allocation. The results of the research are presented in two parts. The first part presents the main assumptions of the theory of property rights, the issue of state interference in the scope of property rights and the resulting consequences for trade in land. In the second part, the market and non-market transfers of physical property were analyzed. Based on the obtained results, it was found that there are possibilities for further development of the market, and there are premises for a gradual improvement in the efficiency of land allocation in Poland.
