The aim of the study is to determine the impact of foreign economic security of agricultural producers on the integration and stability of the EAEU. The positive and negative impact of exports and imports on economic growth in the industry and economy, which can pose threats to foreign economic security, is highlighted. Indices of gross added value of agricultural goods, structure of export and import of goods by purpose in dynamics for 2015-2019, changes of share of export and import of agricultural raw materials and food products were analyzed. A conclusion was made about similar trends in the EAEU member states in the dynamics of agricultural production, the growth of food exports, a decrease in imports, the impact of the export and import of agricultural raw materials and food products of the EAEU member states on the economic growth of the agricultural industry.

The economic policy pursued has turned China into a major trading power. In terms of GDP, the Chinese economy has been the first economy in the world for a number of recent years; China’s rapidly growing trade flows have made it the largest trading partner for many countries. Over the past twenty years there has been rapid growth in exports and imports. The article puts forward a hypothesis about the presence of structural instability in the dynamics of Chinese exports for the period from 2000 to 2020. The hypothesis was confirmed and two periods were identified in the dynamics of exports and imports with different natures of the main development trend: from 2000 to 2008 and from 2009 to 2020. For each stage, trend equations were selected that describe the dynamics of exports and imports and an interval forecast of indexes for 2021 was made. Materials and methods. During the work, dynamic, structural analysis of analytical and statistical information was used; methods of analytical, logical, systemic, correlation and regression analysis were used, as well as analysis of structural changes. The analysis was carried out using the Statistica 10.0 program.Results. A change in the value of the import coverage ratio by exports was revealed before and after structural changes in the dynamics of the main foreign economic indexes and an assessment of their statistical significance was given. An analysis of the influence of export dynamics on GDP dynamics was carried out and it was found that before structural changes, the influence of export dynamics on GDP dynamics was statistically insignificant, and after a structural change, export dynamics began to have a direct impact on changes in China’s GDP. Conclusion. Analysis of official statistical data on the main indexes of China’s foreign economic activity for the period from 2000 to 2020 allowed us to note that the volume of Chinese exports increased over the period 2010-2019 from $1.58 trillion in 2010 (10.34% of global exports), to $2.50 trillion in 2019 (12.81% of global exports). In 2019, China continued to rank first in terms of export value among all countries in the world. Despite the challenging year of 2020, China’s exports reached almost 2.6 trillion US dollars and increased by 4% compared to 2019.China also occupies a leading position in the export of high-tech goods - their volume is 731.9 billion US dollars, the share of exports in the global volume is 25%. At the same time, the dynamics of Chinese exports for the period from 2000 to 2020 was heterogeneous and characterized by structural instability. Two stages can be distinguished with different characteristics of the main development trend: from 2000 to 2008 and from 2009 to 2020. Based on this, the authors came to the conclusion that to describe the main trend in the development of export and import dynamics for the period from 2000 to 2008, the exponential model is best suited. To describe the main trend in the development of export and import dynamics in the period from 2009 to 2020 - logarithmic model. A study of the consistency of changes in export and import volumes showed that in the period from 2009 to 2020 was characterized by greater consistency in China’s main foreign trade flows than the period from 2000 to 2008. In the period before the structural change in the dynamics of exports and imports, the coverage ratio varied from 105.7% to 127.6%; in the period after the structural change, the coverage ratio changed from 108.9% to 135.4%.Checking the statistical significance of the differences in the coefficient of coverage of imports by exports before and after the structural change showed that the differences are not statistically significant. In the period from 2000 to 2008 the dynamics of China’s exports did not have a statistically significant impact on the dynamics of the country’s GDP. From 2009 to 2020 after structural changes in the nature of the dynamics of the main indexes of China’s foreign trade, changes in exports began to have a statistically significant impact on the dynamics of GDP. A 1% increase in China’s exports now results in a 0.25% increase in GDP.The practical significance of the paper is determined by the developed methodology for analyzing structural changes in the dynamics of exports and imports, examined using the example of China.

The importance of statistical assessment of foreign economic activities in Ukraine, considering the structure and geographical re-orientation of the Ukrainian foreign trade and new challenges of the globalized and highly competitive market of goods and services, gives rise to the modeling of patterns underlying future tendencies in the development of the Ukrainian foreign trade. The article contains a description of approaches to the analysis of foreign economic activities in Ukraine by use of index models. Several index models are constructed and used for assessing the debt burden of Ukraine, the impact of selected sub-factors on it are determined, and the dynamics of the export quota in 2016–2017 are highlighted
 By use of the chain substitutions method it is found that the debt burden of Ukraine decreased in 2017, compared to 2016, by 21.0% due to the reduced import dependence of Ukraine, by 12.0% due to the partial debt burden, but increased by 4.1% due to the export losses. The results show that the strongest impact on the dynamics of debt burden of Ukraine came from the import dependence (56.6%), which means that the strict import quota remains the main factor of the increasing foreign debt of Ukraine, which caused 5.9% loss of export earnings in 2016, and 2.3% in 2017.
 The analysis of the export quota dynamics based on the index model showed that the impact of the international intraspecific specialization of the country on it was 43.2%, and the impact of the exports’ share in the foreign trade balance made 44.7%. That is, the main factors of change are the commodity and geographical specialization of Ukraine, as well as the imbalance in the foreign trade.
 Results of the analysis of the indices of averages show that due to the growth in export quotas of products of vegetable origin, fats and oils by 12.7%, and under the influence of the commodity structure of exports (–8.4%), the export quota increased by 3.2% in 2017 compared to 2012. The import quota of goods decreased by 17%, including by 7.6% due to the reduced import dependence of the country, and by 10.1% due to the changed structure of imports.
 Results of the analysis indicate significant change in the trend of export and import quotas of Ukraine on account of geographical reorientation: due to changes in the geographical structure of exports and imports of Ukraine, the export and import quotas decreased by 41.5%, and 32.2%, respectively.
 The analysis of the commodity structure of the Ukrainian foreign trade in 2012–2017 shows that the largest export positions were non-precious metals (ferrous metals and products made thereof), grain crops, fats and oils, electric machinery; in the exports of services, the largest share was accounted for by transport services, telecommunication services, computer and information services, processing of material resources, and business services. In the commodity structure of imports, mineral products had the largest share, which, however, decreased by 7.36 percentage points in 2017 compared to 2012. Imports of services are dominated by transport services and government services.
 The Russian Federation remains to be main partner in export-import operations of Ukraine: 9.1% of the Ukraine’s exports of goods in 2017, which is 16.53 percentage points less than in 2012; and 14.5% of the imports of goods in 2017, which is 17.86 percentage points less than in 2012. The main partner of Ukraine in the imports of services is the U.S., with 11.78% of the total imports of services in 2017, which is 6.7 percentage points more than in 2012.

Authors consider export opportunities and the structure and dynamics of industrial export and import in the Russian Federation, Northwest Russia and St. Petersburg. The article studies structural changes in sectors of St. Petersburg economy resulting from ongoing innovation processes and their impact on export potential. It provides the results of assessing the impact of organizational, economic and production factors on export opportunities of various economic entities. Export opportunities, structure and dynamics of export and import of industrial products in the Russian Federation, the North-West region and St. Petersburg are considered. Volume of exports, imports and trade turnover in Russia in 2019, as well as the dynamics of changes in recent years are discussed. In the structure of Russia's exports in recent years, the bulk of supplies (60%) were mineral products, imports the main share of exports (over 40%) occurred in the machinery, equipment and vehicles. The high needs of the national market and the significant export potential of Russian enterprises engaged in the production of medicines and modern medical equipment are noted, which makes it possible to make a real contribution to solving important social problems and developing the national economy. The structure of exports and imports of North-West Federal district and St. Petersburg by major commodity groups, there is a saving in purchases of imported equipment combined with constant growth of exports of fuel and energy products are discussed. Structural changes in the economic sectors of St. Petersburg as a result of ongoing innovation processes and their impact on export potential are studied. The results of the assessment of the impact of organizational, economic and production factors on the export opportunities of various economic entities are presented. It is revealed that for industrial enterprises, the quality and cost of components becomes a problematic factor that hinders their development both in improving the product range and in their own technological modernization. For small and medium-sized businesses in industrial production, problems related to timely receipt of high-quality materials and products of the element base from suppliers and related companies, in most cases located abroad, are added. The role of the “Russian export center” as a state institute for supporting non-commodity exports and facilitating export operations was noted.

Introduction. Foreign trade operations significantly affect the development of each country's economy, in particular the value of gross domestic product, which is one of the main indicators of economic development and welfare of population. Therefore, it is necessary to study and model the impact of exports, imports and net exports on macroeconomic indicators of Ukraine. Purpose. The purpose of the article is to analyze publications that consider export-import operations of Ukraine, study of statistical information in this area, construction and analysis of econometric models of the dynamics of foreign trade operations of Ukraine and their impact on gross domestic product. Method. The article uses regression-correlation analysis as one of the main research methods; time series theory; methods of mathematical modeling. Results. The dynamics of foreign economic operations and gross domestic product of Ukraine are researched and analyzed. It is revealed that the balance of export-import operations has a significant impact on the gross domestic product of Ukraine. An econometric model of the dependence of the nominal gross domestic product on the value of exports of goods and services (coefficient of determination 0.9795) is calculated, using statistical information for 2005-2019 years. It is substantiated that with the increase in exports of goods and services by UAH 1 billion Ukraine's nominal GDP grows by an average of UAH 2.2642 billion. The value of coefficients of import dependence and coverage of import by export in foreign economic operations of Ukraine are analyzed. It is noted that the coefficient of import dependence significantly exceeds the allowable level in the study period, due to certain imbalances in foreign trade relations. The coefficient of coverage of imports by exports only in 2005 was greater than one, and during 2006-2019 it became less than one. In this regard, it is necessary to increase export operations, obtain a positive balance of payments, make effective economic and political decisions to increase exports of Ukrainian goods and services, reduce import dependence, using and implementing innovative methods of production and management.

Border inspections by developed nations are an essential export barrier to developing countries. Import refusals, in particular, not only exhibit dynamic impacts on exporters’ performance in the refused destination but may also spill over into exports toward third markets. Using a panel structural vector autoregression model, the complete dynamics of China’s agricultural export in response to United States Food and Drug Administration (FDA) import refusals is estimated at the monthly level. Despite notable heterogeneities across sectors, negative and positive reactions that last mostly less than a year are revealed respectively for the quantity and price of China’s exports to USA on average. The impact of idiosyncratic component dominates that of common component in the refusal shock, highlighting the sensitivity of exports to sector-specific border inspections. Relative to other refusal charges, larger export contractions tend to follow adulteration charges. The trade effect of FDA refusals spills over into other main export destinations of China. While non-adulteration charges result in trade deflections on average, a contagious export reduction is observed in most non-US markets. These results provide insights for exporters to make strategies with a focus on specific sectors, charges, third markets and especially on the short run to cope with import refusals.

Objective. The purpose of the study is to analyze the current trends of export-import operations between Ukraine and Poland and their specific changes during the full-scale invasion of Russia and in the conditions of military operations, to forecast the volume of export-import operations between the countries.. Methods. During the research, the following was applied: the dialectical method of learning processes and phenomena (to study the essence of export-import operations between Ukraine and Poland); graphic method (to display the dynamics and structure of export-import operations between Ukraine and Poland); index (to assess the rates of growth of the investigated indicators); the method of correlation analysis (to study the relationships between export and import operations between Ukraine and Poland), the method of one-factor and two-factor autoregression forecasting (to forecast sales volumes of manufactured products in general and depending on the size of production). Results. As a result of the conducted research, it was found that with the beginning of the full-scale war with Russia, the volume of trade relations with Poland increased significantly. In 2022, Poland took the first place among the exporting countries from Ukraine and the second - in terms of the volume of imports to Ukraine, second only to China - despite the fact that, as a whole, imports to Ukraine (from all countries in general) almost halved. That is, the increase in trade between Ukraine and Poland during the full-scale invasion took place against the background of a very significant reduction in Ukraine's international trade as a whole. In 2022 for the first time in the last 20 years, the volume of exports to Poland exceeded the volume of imports from Poland. This is due to the fact that during a full-scale war, the destruction of most airports and the blocking of sea trade routes, Poland turned into the main international hub for foreign trade with Ukraine. One- and multi-factor autoregressive forecasting of export and import volumes between Ukraine and Poland was performed and the expected growth of exports from Ukraine to Poland in 2025 was calculated. up to 7-10 million dollars, and imports in the amount of 4.5-5 million dollars. The accuracy of the obtained autoregressive forecasts is 81.3%-83.5%.

The directions of statistical analysis of the country’s foreign trade processes are considered in the article. Possibilities of statistical methods for studying the state and the main trends that have developed in this area are highlighted. The conclusions about the intensity of the dynamics of the trade balance indicators are generalized. The processes of the outstripping development of imports over exports are highlighted. The dynamics of the balance of export-import operations is analyzed and trends of its deterioration are demonstrated. The degree of coverage of imports by exports and the processes of formation of the trade balance deficit are investigated in time. The directions of development of characteristics of the balance of foreign trade operations are studied. High levels of export and import dependence of the country have been demonstrated, which leads to vulnerability to external shocks and instability in the world. The results of the analysis of the structure and structural shifts in the trade of Ukraine with the countries of the Visegrad Four are presented. The emphasis is made on the prospects of interrelations with this group of countries from the point of view of using their experience in preparing for accession to the EU. The article demonstrates more intensive changes in the geographical structure of exports than imports and highlights the tendencies towards an increase in the role of Poland and a decrease in Hungary in the export-import operations of the Visegrad Four with Ukraine. The processes of changing the terms of trade have been investigated in terms of changes in export and import prices and in terms of changes in the physical volume of exports and imports on the example of a group of dairy products, which are widely represented among both export and import goods of Ukraine. The index method was used to analyze the absolute and relative impact of changes in prices and the physical volume of exports and imports of a number of dairy products on the value of exports and imports. Changes in the terms of trade are highlighted by constructing quantitative and price indices of the terms of trade. It was clarified that it was the sharp reduction in the physical volume of exports that contributed to the decrease in foreign exchange earnings from the export of dairy products. The necessity of measures to promote domestic goods abroad, primarily to European countries, has been substantiated. The research results can be used in foreign trade policy at the macro level.

Currently, the Russian Federation is a significant geopolitical and economic player in the modern global world, it has its own interests and traditional partnerships with most states, including business representatives of those countries that are trying to restrain its development through restrictions and partial isolation from global development opportunities . Despite the sanctions and the unfavorable world market conditions, the Russian economy showed high plasticity, stability and adaptability to external changes, which was reflected in the positive dynamics of foreign trade growth in the existing conditions. Therefore, the purpose of this article was to conduct a comprehensive analysis of the dynamics of official statistics on economic growth and foreign trade in the Russian Federation for the period 2013-2018. To achieve this goal, the following tasks were solved: 1) an analysis of the dynamics of the gross domestic product of the Russian Federation for the period 2013-2018; 2) the role of foreign trade in the gross domestic product of the country is estimated through the calculation of foreign economic quotas; 3) analyzed the dynamics of foreign trade, imports and exports of the Russian Federation; 4) revealed the shares of product groups in the structure of exports and imports, as well as the most significant counterparties of the Russian Federation. The hypothesis of the study was the thesis of the interdependence of the volume of economic growth and foreign economic activity, including taking into account changes in foreign economic conditions. The article provides a retrospective analysis of the dynamics of economic growth in terms of nominal value and purchasing power parity, as well as the dynamics of foreign trade of the Russian Federation for the period 2013-2018. A preliminary forecast of foreign trade volumes for 2019 is given. The calculation of foreign economic, export and import quotas for the same period. The Russian specifics of the dynamics and structure of export supplies and import flows, as well as the structure of both imports and exports by counteragent countries and enlarged groups of the commodity nomenclature of foreign economic activity, are examined. For the period under review, the nominal GDP fell by 28.8%, while in terms of purchasing power parity, the Russian economy grew by 5.7% over the same period. At the same time, the largest drawdown in the economy occurred in the middle of the period; in recent years, the situation in the economy has improved. The role of foreign trade in the formation of GDP during the period was relatively stable, with the exception of 2018, when the foreign trade quota sharply increased (as well as export and import). The dynamics of foreign trade and export quotas in the Russian Federation are almost identical, while imports depend on export earnings. For the study period, foreign trade turnover of the Russian Federation decreased by 18.4%, export volumes decreased by 14.8%, import purchases decreased by 24.5%. The main problem of the economy and foreign economic activity remains its dependence on the export of mineral products.
