Spatio-temporal assessment of the sustainability of agricultural landscapes over a long period (1892–2020 – 130 years) was carried out on the basis of archival spatial data for the territory of the Dnieper district of the Tauride province and modern data from the State Agency for Water Resources of Ukraine. Taking into account the historical patterns of the development of agriculture on the territory of the Dnieper district and the results of spatial modeling in 1892, territories with low (4.1 thousand hectares – 0.3% of the total area) and medium (310.3 thousand hectares – 23.8%) level of sustainability of agricultural landscapes, which are located in the lower reaches of the Dnieper, were identified. However, the large-scale development of the territory for agricultural land and the development of irrigated agriculture have led to the activation of land degradation processes, soil fertility and the deterioration of the stability of agricultural landscapes over large areas. As a result of spatial modeling, the state for 2020 in the irrigation zone recorded significant areas of agricultural land and adjacent territories with low (179.1 thousand hectares – 13.7% of the total area) and medium (419.0 thousand hectares – 32.1%) stability level. A comparative analysis of the stability of agrolandscapes for two time periods (1892 and 2020) showed that large-scale agricultural land development and an imbalanced land-use culture lead to constant and almost irreversible processes of reducing the stability of agrolandscapes in the areas of irrigation reclamation.

Successful operation and development of enterprises in modern conditions involves the expansion of markets. The company's entry into international markets requires the formation of its international competitive strategy, identification of competitive advantages in the markets of selected countries, and this, in turn, implies the need for export potential of the company. In determining the export potential of the aviation complex, it is necessary to consider the specific features of enterprises in this industry, among which we can highlight the features of the products of aviation enterprises and the features of the international aviation market. To qualitatively assess the level of economic potential, we propose to use a system of classification features, developed based on the well-known Harrington scale, but slightly modified by the authors in relation to the calculated data and available statistical information. The phases of the life cycle of the economic potential of the enterprise are determined. Not only the quantitative and qualitative level of economic potential are important, but also the changes associated with the passage of time. In order to determine the importance of indicators in each group, methods of component analysis of the characteristics of variation series of the results of the survey of experts were used. When comparing the variation of different features in one set with different average value, we use the relative indicators of variation - coefficients of variation. The obtained result together with the results of application of the method of component analysis allows us to conclude that in the formation of the integrated indicator of the first group (K1) it is enough to consider these five indicators, and the most important of them are two: technological processes to other activities.

The study is devoted to the development of proposals for improving the assessment and stimulating the export potential of an innovatively active enterprise. The authors examined the essence and features of the activities of innovatively active enterprises, as well as the impact on their export activities. The conducted theoretical and methodological study allowed the authors to show their vision of the main components of the export potential of the enterprise, and also, in order to assess and analyze the export potential of an innovatively active enterprise, they proposed an economic and mathematical model, a feature of which is taking into account the hidden export potential, which has a significant economic impact. To stimulate the export potential of an innovatively active enterprise, the authors proposed a system of labour force motivation, as well as institutional instruments, which have a significant social impact.

The work is aimed at analysing the state and prospects of implementing the export potential of the agrarian sector of Ukraine, the structure of which is based on the principles of transition from the abstract to the concrete. The study begins with the definition of factors that shape the export opportunities of the agrarian sector, namely: the quality of the factors of agricultural production (objects of labour, means of labour); the branch structure of agricultural production; the state of the systems of certification and quality control of export products; the diversification of markets; the access to financial resources; the level of the marketing support of export; the mechanisms of the realization of the state export policy; the state of development of agro-logistics. It has been proved that in the short term, the production components are not decisive in the processes of using and expanding the existing export potential of the national agrarian sector. In the modern conditions the state of logistics infrastructure is coming to the forefront. In the general problem of agro-logistics, the following levels are distinguished: micro-, meso-, macro-, and supranational. In each of them we have identified "the bottlenecks" of the process of building up export potential from the point of view of agro-logistics. The ways of increasing the export potential of the agrarian sector in Ukraine have been proposed. These include: the development of container transportation sphere; the creation of effective mechanisms for directing funds of united territorial communities for the development of regional logistics infrastructure; the reform of Ukrzaliznytsia (JSC „Ukrainian Railways”); the development of alternative variants of supply chains by improving the infrastructure of the automobile and river transport; the expansion of the representation of Ukraine in the world governmental and non-governmental organizations in order to protect the national trade interests; the formation of the system of training personnel capable of adapting to changing market conditions.
