E-commerce is one of the fastest and most effective ways to trade in e-space. The leading role in the development of the digital economy and e-commerce belongs to the EU countries that use e-commerce to achieve the goals of sustainable development. The main target of e-commerce companies is to ensure the flexibility and adaptability of the e-commerce development management system. Purpose: to research of the state and prospects of e-commerce development in the EU countries, as well as the content and components of e-commerce development process management. Methods: systematization, generalization, comparative analysis, correlation analysis to build a correlation matrix. Results. The state of e-commerce in the EU countries is studied (according to the following indicators: the share of e-commerce in the total retail sales of individual EU countries, the share of the population shopping online, turnover from e-commerce in small businesses in the EU, etc.). A correlation analysis of the main indicators used to assess the market of electronic trade in the EU, the results of which proved that there is a direct relationship between the dynamics of these indicators and the dynamics of operating profits of enterprises in the EU.

Transformations of the tourism market structure in a pandemic necessitate a study of the extent to which EU countries can provide their citizens with tourism products to minimize the negative impact of the pandemic and, consequently, the negative impact on economic development. This article aimed to develop recommendations for minimizing the negative impact of reducing regional tourism on economic development through the support of domestic tourism. This research uses a quantitative methodology based on indicators of growth of tourist external and internal flows in the regions, the growth rate of economic regions of the EU for 2015-2019. The following countries were selected for correlation analysis: Belgium, Bulgaria, Czech Republic, Germany, Estonia, Greece, Spain, and Italy. The analysis of the impact of regional tourism on economic development in the EU for 2015-2019 indicates the need to develop regional strategies for smart specializations of the tourism industry based on the most attractive industries for tourists. It is determined that within the EU, economic development is less dependent on developed tourist regions due to potentially low tourist costs, as a result - short-term revenues from the industry. It is proved that regions with a high level of tourist flows can provide economic development by increasing the innovation of industries related to tourism, as such industries attract tourists. In a pandemic, businesses need to focus on promoting regional products and shift the focus to domestic consumption within the country. The theoretical value of this study is that regional tourism affects the economic development of the EU countries through the total costs of tourists, the volume of which in the short term has a negligible impact on the region's development. At the same time, the income of the tourism industry as a contribution to the economy is overestimated in the scientific literature.

In this article we have considered methods of information and analytical support used in the formulation of a sustainable economic development strategy for industrial enterprises. The purpose of this study is the methodological and applied justification for choosing a scenario for sustainable development in the system of strategic management of industrial enterprises in order to improve their performance indicators, competitiveness, and social responsibility. We have offered a methodical approach for the criterion assessment of qualitative, quantitative, and financial indicators of both the enterprise and the external environment's strategic potential. Analysis of enterprise management systems has been carried out on the basis of calculations taking into account the national program of sustainable development, and a further strategy for the development of industrial enterprises has been offered. It is substantiated that, to form effective strategies aimed at ensuring sustainable economic development, an analytical system of support for strategic decisions is needed. One of the components of such a system is a set of adequate mathematical models that will determine the key factors of the internal environment at an enterprise that affect its sustainable development. Its usage in practice will allow for the optimization of costs in functional areas when developing corporate decomposition strategy, and will allow for the building of determining factor models, the reflection of the relationship between key indicators, the compilation of forecast reports, and the performing of both situational and sensitivity analysis.

The development of trade sector of the Ukrainian economy triggers the need to study the processes of formation and evaluation of the retail business efficiency taking into account the current conditions of economic development. The objective of research is a methodology for assessing the performance of retail. The proposed methodology is based on the target, resource, dynamic approaches to the efficiency assessment and contains determined efficiency indicators in accordance with evaluation criteria. The indicators of the efficiency assessment take into account the specifics of the retail according to the subjects of assessment: retailer, consumer, competitor, supplier. Proposed methodology for assessing the efficiency allows us to calculate indicators in accordance with the selected approaches to the assessment and identify the problems to be addressed by the retailer’s management. Considering the requirements and interests of stakeholders to assess the efficiency of retail businesses helps to achieve the most recent competitive advantages.
