Development vs efficiency of Polish farms - trade-off or synergy effects?

Abstract

he article aims to determine the nature of the relationship between farm development and its technical efficiency understood from the perspective of data envelopment analysis (DEA). The time scope of the analysis refers to the period 2004-2019. The empirical part of the article is based on the individual unpublished data for Polish farms conducting agricultural accounting according to Farm Accountancy Data Network (FADN). We employed a super-efficiency slack-based DEA model with variable returns to scale. This model enables us to compare and rank efficient farms as well as investigate the sources of farm (in)efficiency. We did not identify the substitution (trade-off) effect between farms` sustainability and efficiency. For level of technical efficiency and these differences were statistically significant. The main policy recommendation that can be derived from these results is that agricultural policy should support both efficiency improvements and progress toward higher sustainability.

Assessment of the spatial disparities of the green economy in the voivodeships of Poland in 2010-2020

“…In Poland, the transition to renewable energy sources is a mix of various energy sources. Grzelak and Kryszak (2023) presents a model that allows for comparison and ranking of efficient farms and examination of the sources of progress of (in)efficiency of farms towards greater sustainability (or green econ-ECONOMICS AND ENVIRONMENT 4 (87) • 2023 DOI: 10.34659/eis.2023.87.4.699 omy). As Borys et al (2022) point out, achieving climate goals is becoming a challenge facing humanity in the green transformation of the regional economy.…”
