The COVID-19 pandemic impacted every aspect of life on a global scale. E-business has become a key factor influencing the profitability of businesses in various fields, regardless of their size. The aim of this study was to assess the effectiveness of e-business in entrepreneurship development in various fields during the COVID-19 pandemic. For this purpose, a panel analysis of data from 212 micro, small, medium-sized and large companies, and nine business sectors (trade, chemical, light, pharmaceutical, food, agricultural, HoReCo (hotel and restaurant industry), electronics and IT, transport) was used with data comparison for 2019 and 2020 in Ukraine, Bulgaria, Poland, Moldova and Georgia. The e-business platform was found to be the key indicator of maintaining performance during a pandemic. The analyzed questionnaire data show that 58% of respondents saw an increase in online income in 2020 compared to 2019 that in such sectors as trade, IT and pharmacy. There were 59% of respondents who saw the need to expand communication networks with existing and potential customers, because it was positively correlated with the efficiency of e-business. Besides, the results show that equity financing and proper liquidity management consolidate the economic performance of businesses in terms of return on equity and return on assets. Our findings are useful to managers and investors, and can help them make the best decisions about their management or investment activities. Moreover, the study demonstrates how companies were responding to the pandemic in order to identify sectors that are more vulnerable to the effects of the crisis and the key financial management decisions that companies need to make during the crisis.

Modern logistics significantly influences the globalization and internationalization processes. Logistics systems are becoming increasingly important in today’s rapidly changing environment. The aim of the article was to investigate the national logistics systems of developing countries in the context of their integration capabilities. The main methods used in this study are statistical analysis, index, graphical and analytical methods, methods for estimating structural dynamic shifts, comparisons. Commonly used methods of economic research, as well as statistical analysis and interstate comparisons, economic modelling (trend analysis to determine the forecast level of LPI for Ukraine), etc. were also involved. The logistics environment of Poland, Bulgaria, India and Ukraine, as well as the factors of its formation are evaluated. The components of the logistic portrait of the country in the context of integration capabilities of the logistic system are offered. It was found for the studied countries that the destimulator of the national logistics system is infrastructure (for Poland), infrastructure and customs (for Bulgaria and Ukraine), customs (for India). It is these components that need priority attention in the context of increasing the integration capabilities of logistics systems, because the results indicate that they lag far behind international standards. Prospects for further research involve studies of the impact of pandemics, globalization, digitalization on logistics systems, including that of developing countries.
