This study examines whether regional readiness for green transition practices is associated with better agricultural-economic performance in Western Ukraine. Because farm-level readiness data are not consistently available, the paper builds a transparent set of oblast-level readiness proxies using official statistics on (i) (i) (i) (i) the share of sown area treated with mineral fertilisers, organic fertilisers, and pesticides, and (ii) mineral fertiliser intensity (kg per hectare). Performance is measured using gross regional product (GRP) as an auditable macro proxy for regional economic outcomes during the overlapping period covered by publicly accessible statistical publications. The empirical strategy applies fixed-effects regressions with year controls and robustness checks using alternative index construction. Results indicate that the composite readiness index is not robustly associated with higher regional performance in the short sample window, while individual input-intensity components show statistically detectable within-region associations that are sensitive to specification and the limited time coverage. The findings suggest that, under data constraints and wartime disturbances, aggregate economic indicators may not immediately reflect environmental-practice reahighlightinghasising the need for longer panels and sector-specific value-added measures. The paper contributes a replicable, data-auditable workflow for green-readiness measurement using official statistics, with clear limitations and directions for improving inference.
