Agroholding companies play a significant role in the development of the domestic agro-industrial sector and the national economy, and over the past 10 years have become the leading form of agricultural business in Ukraine. Agrarian holdings accumulate significant financial resources, have access to the latest technologies and access to export markets, have a political and socio-economic impact at the regional and national levels. At the same time, the functioning of large agroholding structures is characterized by many negative manifestations, in particular, the monopolization of land lease and agricultural products markets, the gradual displacement of small and medium agrarian businesses, and the presence of a significant number of problems in ensuring the environmental safety of the regions of its presence.
The purpose of the article is to analyze the threats of functioning of agroholding companies in Ukraine and outline the main directions of their neutralization.
Analysis of the activity of agroholding structures in Ukraine allowed to identify and confirm scientifically the following threats of their functioning for the domestic agricultural sector and the economy as a whole: 1) monopolization of the land lease market; 2) a constant increase in the area of cultivated land with a small percentage of Ukraine in world exports of agricultural products; 3) monopolization of the market of agricultural products, which occurs by capturing large agro companies the most profitable and export-oriented spheres of agribusiness; 4) the absorption of small enterprises; 5) limiting of the opportunities for the development of personal peasant and farm enterprises, primarily because of the problem of obtaining credit resources and their high cost; 6) uncontrollability of ways of using the soil and as a consequence - deterioration of their qualitative characteristics.
In order to neutralize the negative influence of agroholding structures in the context of these threats, the author proposed a complex of urgent measures in the following key areas: elimination of monopolization manifestations in land lease and agricultural products markets, formation of effective mechanisms for the development of small and medium agribusiness, and implementation of measures to combat degradation of agricultural lands and their pollution. Within the frameworks of the priority directions, strategic goals and tools for their implementation have been developed.
The author believes that the proposed measures will help to eliminate the risks arising from the activities of large integrated agroformations, which will improve the business environment, increase the competitiveness of agricultural production in the domestic and foreign markets and, as a consequence, increase the state food security.
