Introduction. The export potential of the regional agricultural market causes great interest from both the scientific community and government agencies. Many scientific studies are devoted to the search for methods to increase the export potential in order to ensure the sustainable development of regional economic systems. The article proposes and tests the original author’s algorithm for creating a dynamic econometric model for forecasting the volumes of production, sales and exports of the main types of livestock products at the regional level. The purpose of the article is to assess the export potential of the main products of the regional agricultural market based on the built dynamic econometric models. Materials and Methods. The research is based on a set of empirical data of result and input variables characterizing the production, sales and export of the main livestock products in the region for the period 2010-2020. Research methods include dynamic analysis, econometric modeling and forecasting. The dynamic analysis carried out made it possible to assess the change in the production, sale and export of the main agricultural products in the region, to assess the current trends. Based on the constructed econometric models, the most significant factors influencing the resulting variables were identified, the specifications and verification of the models were carried out. The method of extrapolation of the identified trends made it possible to evaluate the predicted values of the resulting variables for the medium term. Results. Based on the selected input variables, models of production, sale and export of milk, wool and eggs by agricultural producers in the region were built. From a variety of alternative models, models with the best statistical quality characteristics were selected. The high level of quality of the obtained models made it possible to use them for predictive calculations of the levels of resulting variables for the period 2021-2026. Comparison of the results of the forecasts made it possible to identify the types of livestock products that already have a high level of exportability. In addition, types of products with a low level of exportability were identified, which have a high potential for increase. Discussion and Conclusion. As a result of using econometric modeling methods, dynamic models were obtained that made it possible to obtain a forecast for the development of livestock in a region with a high export potential in the near future. The practical significance of this article lies in the possibility of influencing the production, sale and export of livestock products in the region through a change in the corresponding set of factor variables of the models. Thus, the resulting dynamic models can be used both by agricultural producers for planning economic activities, and by regional authorities when drawing up regional development programs.

Введение. Экспортный потенциал регионального рынка агропродукции вызывает огромный интерес со стороны как научного сообщества, так и государственных структур. Многие научные исследования посвящены вопросам поиска методов увеличения

- экспортного потенциала в целях обеспечения устойчивого развития региональных экономических систем. Цель статьи – на основе построенных динамических эконометрических моделей оценить экспортный потенциал основных продуктов рынка агропродукции региона.

Материалы и методы. В основе исследования лежит набор эмпирических данных целевых и входящих переменных, характеризующих производство, реализацию и экспорт основных видов продукции животноводства региона за период 2010–2020 гг. Проведенный динамический анализ позволил оценить изменение производства, реализации и экспорта основных продуктов сельскохозяйственного производства в регионе, выявить сложившиеся тенденции. На основании построенных эконометрических моделей были определены наиболее существенные факторы, оказывающие воздействие на результативные переменные, проведены спецификация и верификация моделей. Метод экстраполяции выявленных тенденций помог определить прогнозные значения результативных переменных на среднесрочный период.

Результаты исследования. На основе отобранных входящих переменных были построены модели производства, реализации и экспорта молока, шерсти и яиц сельскохозяйственными товаропроизводителями региона. Из множества альтернативных вариантов были отобраны модели, обладающие наилучшими статистическими характеристиками качества. Высокий уровень качества полученных моделей позволил использовать их для прогнозных расчетов уровней результативных переменных на период 2021–2026 гг. Сопоставление полученных результатов прогнозов позволило выделить виды продукции животноводства, которые уже обладают высоким уровнем экспортируемости. Кроме того, были определены виды продукции, обладающие низким уровнем экспортируемости, который имеет высокий потенциал для увеличения.

Обсуждение и заключение. В результате использования методов эконометрического моделирования получены динамические модели, позволившие спрогнозировать развитие животноводства в регионе, имеющем высокий экспортный потенциал на ближайшую перспективу. Практическая значимость исследования заключается в возможности воздействия на производство, реализацию и экспорт продукции животноводства региона через изменение соответствующего набора факторных переменных моделей. Таким образом, полученные динамические модели могут быть использованы как сельскохозяйственными товаропроизводителями для планирования хозяйственной деятельности, так и органами региональной власти при составлении региональных программ развития.

Introduction. The study of the level of export potential of the regional market of agricultural products is of particular relevance against the backdrop of the need to ensure food security both at the regional and federal levels. The purpose of the study is to assess the existing exportability potential of the agro-product regional market, economic and mathematical modeling of existing trends in its development, as well as forecasting the prospective exportability potential of agricultural products.

In this research, the authors tried to consider the potential for export-oriented livestock production in the region. The types of these products include those that already have a fairly high level of exportability (for example, milk). In addition, we consider it necessary to include in the consideration also the production of such types of products that currently have a rather low level of exportability, but at the same time have a high potential for increasing the exportability of products in the future (for example, the production of wool and eggs).

Literature review. Some researchers note that achieving sustainable development goals, increasing competitiveness and gaining access to foreign markets is a difficult task, but this is a prerequisite for exporting products to foreign markets [1].

Many publications are devoted to the issues of the impact of the COVID-19 outbreak on the disruption of agricultural supply chains. So, the scientists found that although the average export of agricultural enterprises decreased, the export of some agricultural products remained strong and even increased. This fact indicates a significant demand for basic foodstuffs during the pandemic [2]. N. Mtimet, F. Wanyoike, K. M. Rich, I. Baltenweck emphasize the multifaceted and often overlooked socio-economic and socio-cultural impacts faced by the livestock sector and the wider economy as a result of public health restrictions [3]. C. Béné, D. Bakker, M. J. Chavarro, B. Even, J. Melo, A. Sonneveld present global assessments of the impact of COVID-19 on food systems and their actors, focusing on the food security and nutritional status of those affected in low- and middle-income countries [4].

Domestic authors note that an important component of the development of the regional economic system is the provision of import substitution and the establishment of food security [5]. The researchers identify six enlarged groups of food products, for which there is a possibility of exporting food to other regions of Russia [6]. These groups of goods also include milk and dairy products, meat and meat products, eggs [7].

K. R. Chegini, M. R. Pakravan-Charvadeh, M. Rahimian, S. Gholamrezaie assessed the relationship of household livelihoods and income inequality with the sustainability of regional economic systems in rural areas [8].

J. Clapp, W. G. Moseley, B. Burlingame, P. Termine believe that the definition of food security needs to be updated. Thus, the authors propose to understand food security as based on six key pillars: availability, access, use, stability, activity and sustainability [9].

S. J. Smyth, S. R. Webb, P. W. B. Phillips believe that public-private partnerships allow the use of market mechanisms to improve agri-food systems, thereby reducing food insecurity and promoting rural development [10].

The issues of the development of the Russian agro-industrial complex in the context of economic sanctions are discussed in the works of R. M. Nureev, E. G. Busygin, A. V. Gorbatov, O. A. Kryoshina, O. G. Chaplygina. The authors specifically note that the livestock industry is in a difficult position. At the same time, the high agricultural potential of Russia is noted [11–13].

Methodical issues of assessing the state and development of the potential of regional livestock breeding are considered in the works of S. G. Chernova, O. P. Zaitseva, O. A. Kozlova, L. Reuter, N. Eremeeva, I. Vedenkina, A. Akopyan [14–16].

The formation of the cost of certain types of livestock products was dealt with by L. M. Chekmareva and E. I. Enina. The authors note that the cost of livestock products is formed under the influence of many technical and technological, external and internal, main and secondary factors. The most important of these factors, the authors consider the productivity of farm animals and the cost of their maintenance [17].

V. Rohr, J. Blakley, P. Loring contains the study of the criteria and approaches to assessing the prospects for the development of regional economic systems. They should be aligned with established principles and procedures for regional strategic environmental assessment (RSEA) to inform the development of a conceptual framework to guide food security assessment in RSEA initiatives [18].

H. Deléglise, R. Interdonato, A. Bégué, E. Maître d’Hôtel, M. Teisseire, M. Roche built a food security forecast based on heterogeneous data based on state-of-the-art machine learning and deep learning models. The authors believe that modern data processing methods make it possible to obtain the most reliable forecasts [19].

Thus, modeling the agricultural products market and using the models obtained will allow not only to state the existing high level of export-oriented agricultural products in the region, but also to reveal the export potential of types of products that have a low level of exportability and a high potential for its increase in the future.

Materials and Methods. To assess the level of potential exportability of the main types of livestock products in the region, it is advisable to use dynamic econometric models. Such models make it possible to identify current trends in the production, sale and export of livestock products. In addition, the practical application of dynamic models makes it possible to predict the behavior of the studied indicators in the future with a certain degree of accuracy. Statistical quality characteristics obtained as a result of constructing econometric models make it possible to evaluate the quality of the models obtained and the forecasts made.

That model was fitted to a data set as the best model. Verification of the model indicates its practical applicability. Thus, the value of the F-test for milk production model indicates that the factorial variance exceeds the residual by 40.8 times. The p-value shows the probability of error at which it is permissible to reject the null hypothesis and accept the alternative. So, the probability of such an error is 2.1% for milk production model.

Therefore, we can conclude that the model is highly significant. The R-squared level estimates the degree of accuracy with which the resulting regression equation approximates the original data. In accordance with it, the volume of milk production by agricultural organizations of the Stavropol region was explained by 97.3% by the variation of the factors included in the model.

Verification of the model indicates its high practical applicability. The obtained values of the regression coefficients allow us to conclude that the profitability of milk production, direct labor costs for milk production and milk production has a significant effect on the volume of milk exports. Thus, an increase in the profitability of milk production by 1%, milk exports will increase by 0.3 thousand tons. At the same time, an increase in the direct labor costs for milk production by 1 thousand man-hour will affect the increase in export volume by 0.92 thousand tons. Milk export directly depend on the volume of its production: an increase in milk production by 1 thousand tons, export volume will increase by 0.84 thousand tons.

The high quality of the econometric models obtained allows them to be used to assess the forecast levels of production, sale and export of milk by agricultural organizations for the period 2021–2026.

Thus, an increase in the egg production by 1 million, egg exports will increase by 0.7 million. In addition, an increase in the Profitability of egg production on 1% affects the increase in egg export volume by 0.06 million.

Discussion and Conclusion. Built on the basis of the proposed algorithm, dynamic econometric models of production, sale and export of the main types of livestock products in the Stavropol region are distinguished by a high level of statistical quality characteristics. This allows you to successfully use them to predict the presented indicators in the short term.

The forecasts of the result variables of the milk production, milk sales and milk export models are presented in Figure 2.

In accordance with the forecast results, milk production in the Stavropol Territory from 2021 to 2026 will increase from 139.8 to 143.5 thousand tons, that is, there will be an increase of 3.7 thousand tons, or 2.6%.

Milk sales in the Stavropol Territory from 2021 to 2026 will increase from 138.4 to 142.2 thousand tons, that is, there will be an increase of 3.8 thousand tons or 2.7%.

Despite the expected increase in milk production, its exports are expected to decline during 2021–2026 in accordance with the results of forecast calculations. Milk exports in the Stavropol Territory from 2021 to 2026 will decrease from 81,1 to 80.6 thousand tons, that is, there will be decrease of 0,5 thousand tons or 0.7%.

The forecasts of wool production, wool sales and wool export models are pre-

F i g. 3. Results of forecasting production, sales and export of wool, tons

In accordance with the forecast results, wool production in the Stavropol Territory from 2021 to 2026 will decrease from 5,756.5 to 5,025.8 tons, that is, there will be decrease of 730.7 tons or 12.7%.

Wool sales in the Stavropol Territory from 2021 to 2026 will decrease from 4,715.1 to 4,557.9 tons, that is, there will be decrease of 157.1 tons or 3.3%.

Wool exports in the Stavropol Territory from 2021 to 2026 will increase from 843 to 988.5 tons, that is, there will be an increase of 145.5 tons or 17.3%.

Thus, the share of the exported volume of produced wool is insignificant. It does not exceed 20%.

The forecasts of the result variables of the egg production, egg sales and egg export models are presented in Figure 4.

In accordance with the forecast results, egg production in the Stavropol Territory from 2021 to 2026 will increase from 803.7 to 858.8 million, that is, there will be an increase of 55.1 million or 6.9%.

Egg sales in the Stavropol Territory from 2021 to 2026 will increase from 404.4 to 412.1 million, that is, there will be an increase of 7.7 million eggs or 1.9%.

Egg exports in the Stavropol Territory from 2021 to 2026 will decrease from 25.1 to 23.1 million, that is, there will be an decrease of 2.1 million or 8.2%.

F i g. 4. Results of forecasting production, sales and export of egg, millions

The results of the forecast allow us to conclude that the export potential of milk production can be considered quite high. At the same time, the expected export volumes obtained on the basis of forecast calculations will decrease in the coming years.

The results obtained for the production, sale and export of eggs and wool in the Stavropol region show a significantly lower level of exportability of these types of products. In addition, export volumes will also decline until 2026. However, it should be noted that this may mean that these areas of livestock production have a high potential for increasing the volume of exports of agricultural products presented.

As a result of the study, it was found that the livestock sub-sector of agricultural production in the Stavropol Territory is characterized by an uneven export potential of certain types of products. The practical significance of the obtained models and predictive estimates lies in the possibility of making informed management decisions in the regionʼs agriculture, taking into account the expected decline in production and sales of certain types of products in order to influence the required level of exportability. At the same time, the results obtained for products with a high level of exportability allow increasing the potential for their use in the future.
