In the paper the author considered estimation of efficiency, which measures the ability of the company to obtain the maximum output from given inputs. The analysis has been carried out by using deterministic method (on the example of the DEA method, Data Envelopment Analysis). The two-step procedure was proposed, namely the returns to scale were specified in the sample and, basing on that, the efficiency of individual enterprises was assessed. In the paper the data from the companies of a key food processing sector in Poland, namely the meat processing, was used. The analysis covered the period 2006–2011, the sample covered from 195 up to 210 enterprises (depending on the analyzed year).

In the paper the author considered estimation of efficiency, which measures the ability of the company to obtain the maximum output from given inputs. The comparison of results obtained by using two approaches: parametric (on the example of the SFA method, Stochastic Frontier Analysis) and non-parametric (on the example of the DEA method, Data Envelopment Analysis) has been carried out. In the paper the data from the companies of a key food processing sector in Poland, namely the meat processing sector, was used. The analysis covered the period 2006–2011, the sample covered from 195 up to 210 enterprises (depending on the analyzed year).

The TFPV Malmquist index is one of the tools that does not require knowledge of the price level and qives information on factors affecting productivity changes over time. The DEA-based approach allows decomposing of the TFPC indices into:technical change ( Δ T),technical efficiency change ( ΔTE) and scale efficiency change (Δ SE). A panel data from the companies of a key food processing sector, namely the meat processing, was used in the paper. The sample consisted of above 200 objects. The results indicated which of the decomposed indices ( ΔT, ΔTE, ΔSE) had the greatest impact on productivity changes in the analyzed sector.

The issue of eco-efficiency of food processing enterprises is ever-present because of the continuous process of improving the quality standards of raw materials, complying with the procedures in food production, introduction of modern production technology and, above all, due to the large number of actors who are competing for customers in the domestic and foreign food market. In the coming years Polish food processing sector will be facing significant challenges with the inevitable slow and gradual decrease in the cost advantages of raw materials’ prices, as well as ready to eat products. Enterprises, as they constitute the majority in manufacturing business, in the long run will need to determine the efficiency, and hence competitiveness of Polish food processing sector. The aim of the study is to review the domestic and foreign literature od the subject in terms of classification and systematization of the concept of eco-efficiency in food processing sector in Poland. In the theoretical part of the study methods of descriptive, comparative, deductive and synthetic analysis are used. In the practical part of the paper appropriately selected measures adequate for eco-efficiency measurement are presented. The results of the analysis are based on the results of the authors’ own calculations, as well specific findings from business practice both from inland and abroad.

The issue of meat production and meat consumption in Poland, EU-28/27 and in the world is currently a debating point, due to the fact that a balanced human diet includes meat and meat products. Objective and comprehensive analyses and predictions for the future development of the meat market are necessary for the ongoing process of upgrading the quality standards of raw materials, monitoring animal welfare in food production, and ensuring a healthy human diet. The aim of the study is to assess and predict the volume of production and the balance of consumption of pork, beef and poultry in Poland, EU-28/27 countries and worldwide in the years 2000-2022. The article consists of a theoretical part and an empirical part. Methods of descriptive, comparative, deductive and synthetic analysis were employed in the theoretical part. In the empirical part, a synthetic review of the researched issue was conducted using statistical analysis with detailed charts, tables and summaries. The final conclusions of the study consist of the author’s own research results and the achievements of economic practice.
