Industry, which on average accounts for about 60% of commodity exports in the EU-28, with over 58% resulting from the processing industry, plays a key role in ensuring the competitiveness of EU countries. The article aims to simulate the influence of structural processing industry parameters on the industry’s efficiency. Correlation methods and the regression analysis were used to substantiate the hypotheses regarding the effect that the share comprised of high-tech and medium-high-tech industries has on the output structure, and the impact made by the share of imports in the intermediate consumption of those industries on the efficiency (the share of gross value added (GVA) in output) of the processing industry. Based on the criteria indicating the increased technological level and reduced import dependence, economic and mathematical models of optimisation were created for the output structure and intermediate consumption of the processing industry, which were then solved using the linear programming method. The authors present the mathematical proof of the relationship between the change in structural parameters (shares of high-tech and medium-tech industries and the share of imports in the structure of their intermediate consumption) of the processing industry and the ratio of the gross value added/output. The results of the simulation, which were based on data from the European Statistical Office and the Organization for Economic Cooperation and Development, provide an analytical basis for selecting industrial policy benchmarks.

Ecosystem services as part of the gross domestic product account

Celem opracowania jest próba zdefiniowania świadczeń ekosystemów i ich właściwości, wskazanie możliwości oraz warunków uwzględniania ich w wartości produkcji globalnej, w zużyciu pośrednim, w konsumpcji i inwestycjach, jako elementach rachunku PKB. Autorka jest przekonana, że taka integracja kategorii świadczeń ekosystemów i wartości wytworzonych w społeczeństwie w ciągu roku jest niezbędna. Analiza teoretyczna postawionego zadania wskazuje jednak na liczne ograniczenia i brak podstaw takiego rozwiązania, a nawet na podważenie zasadności stawiania takiego celu badawczego. Zarówno rozwijanie postawionej tezy, jak i jej podważenie wymaga dalszych analiz teoretycznych.

This paper attempts to define ecosystem benefits and their properties and tries to point out the possibility and conditioning of incorporating them in the global production scheme. This pertains to indirect utilization, consumption and investments, which are treated as individual components of the GDP account. The author is convinced that such integration of ecosystem benefit categories as well as values that have been generated during one year within the community is essential. Theoretical analysis of tasks posed indicates numerous constraints, lack of principles of such a solution, and in extreme cases attempt to undermine this particular issue. It should be noted that thesis presented herein and its possible invalidation requires further theoretical analyses. This paper indicates both the scope and topics that are discussed.
