Публікація Environmental features of land use formation in the regions of Ukraine(2023) Moskalenko, Anatolii; Ivanov, Dmytro; Shyian, Nataliia; Khalep, YuriiThe objective of the study is a comprehensive evaluation of the level of environmental friendliness of land use in the regions of Ukraine, taking into account the structure of cultivated areas. Methodology / approach. The evaluation of the structure of cultivated areas and the level of productivity in the regions of Ukraine was carried out using the method of complex ranking score. This allowed consolidating data on different crops to a single indicator and evaluating the situation in the regions. The regression method was used to evaluate the dependence of the ranking score on the structure of the cultivated areas and the level of productivity in the regions. A graphical method was also used to display the level of relationship between the studied indicators. Results. It was established that in 2022, the structure of cultivated areas did not significantly differ from the situation in 2020 and 2021. The use of a ranking score of changes in the structure of cultivated areas made it possible to establish that in terms of crop groups, the situation was better in 2022 in the regions of Zakarpattia, Volyn and Rivne. The most violations in the structure of cultivated areas were noted in the regions of Sumy, Mykolaiv and Kirovohrad. It turned out to be the best in the regions of Zakarpattia, Lviv and Volyn in terms of individual cultures. The most problematic situation with respect to the structure of cultivated areas was in the regions of Donetsk, Zaporizhzhia and Luhansk. Originality / scientific novelty. The use of methods of the complex ranking score based on the criterion of environmental friendliness of production (structure of cultivated areas) and the level of its efficiency (crop productivity) made it possible to establish that there is a direct level of connection between these indicators. This fact is proof that the optimal structure of land use has a positive effect on the level of crop productivity. Practical value / implications. The obtained results of the study give grounds for raising the question of creating an economic mechanism aimed at stimulating agricultural enterprises to comply with optimal land use standards in terms of compliance with the structure of cultivated areas.Публікація Cost efficiency in the production of crop products as a factor of formation of competitiveness in international markets(Ceres Publishing House, 2023) Shyian, Nataliia; Kovalyova, Olena; Moskalenko, Valentyna; Murenets, Irina; Kniaz, SviatoslavIt was established that there is a close relationship between the level of costs and the yield of crops. At the same time, there is a manifestation of the law of diminishing returns, which leads to a drop in the level of profitability and profitability of production with an increase in the level of costs. The construction of the dependence of the paired regression of productivity-costs-profit, productivity-costs-level of profitability was carried out. The value of the coordinates of the point of intersection of the dependence of the profit and costs on the productivity of wheat, corn for grain, and sunflower was determined. The economic meaning of the obtained coordinates will be that with a given increase in X (yield), the amount of profit per 1 ha of the sown area will exceed costs per unit of land area following the established dependencies. It is proposed to determine the economic efficiency index of crop production intensity. The calculation of this index made it possible to establish that it was on average 4.506 for sunflower, 2.500 for wheat, and 2.102 for corn. For the first time, the influence of the index of economic efficiency of the intensification of the production of individual crop on the level of their profitability was evaluated. It was established that this rela was non-linear for wheat and sunflower, and linear for grain corn. The practical significance of the obtained results is that the optimal values of the index of economic efficiency and production intensification were determined for sunflower and wheat.Публікація Milk price modeling and forecasting(2021) Shyian, Nataliia; Moskalenko, Valentyna; Shabinskyi, Olexandr; Pechko, VolodymyrThe purpose of the article is to substantiate the methodological approach to forecasting the selling price of milk, which is produced and sold by agricultural producers in the Ukrainian market of raw milk.
