The article investigates trade flows between the Shanghai Cooperation Organization (SCO) member-states and Belarus before the upcoming Belarus’ joining the organization. The export flows of the countries are modeled using a power function based on the time data. The results of the qualitative and quantitative analysis of foreign trade between the organization and the Republic of Belarus are presented, as well as the quantitative forecast of the prospects open to Belarus in connection with its joining the organization based on three original scenarios using econometric models. The results of the study show that Belarus has certain promising sectors of foreign economic activity, which can contribute to an increase in income from trade. It was found that the integration of the country will have a positive effect on increasing the volume of trade turnover with the participating countries, while in order to maintain sustainable economic growth of the country, domestic development of production should remain a priority, as evidenced by the obtained parameter estimates for the factors. An assessment of potential economic effects can be used to make a decision on whether a country should join an international organization. In particular, based on the assessments in our study in trade with Russia the expected increase in Belarus exports upon joining the Shanghai Cooperation Organization will constitute an increase of nearly 5%, exports to Kazakhstan are expected to increase by almost 75%, and to India and China by almost 90%. In the context of reshaping of international associations and organizations, the problems and issues raised in the study become even more relevant.

The development of China's education industry is closely linked to the progress of the country's society.

In the highly developed process of "Internet plus", foreign trade transformation and upgrading, cross-border new retail rapid development has become the trend of the times, cross-border e-commerce new retail digitalization, and improving operational efficiency brings new opportunities. Reshaping the structure of new retail formats, the integration of cross-border e-commerce and new retail formats is an inevitable trend. Smart upgrading and digital transformation are important measures to achieve leapfrog development. The format structure presents business models such as "smart retail, digital cross-border e-commerce, new cross-border e-commerce, new retail, and new retail logistics". The main research objective of this project is to explore and research the new retail scenarios of digital applications in cross-border e-commerce. Based on the current development trend of digital cross-border e-commerce and new retail upgrading, as well as the economic characteristics of the Wuyi area in Jiangmen City, this project aims to use the smart new retail scenario of digital cross-border e-commerce as the foothold, with a focus on upgrading and transforming the product flow chain with the "application scenario" as the central point, form a closed-loop loop of free circulation of products, new retail logistics, cross-border e-commerce, new retail, new sales experience scenarios, and consumers.

Although various actors have examined the user acceptance of e-government developments, less attention has so far devoted to the relationship between attitudes of certain commuter groups against digital technologies and their intention to engage in productive time-use by mobile devices. This paper aims to fill this gap by establishing an overall framework which focuses on Hungarian commuters’ attitudes toward e-government applications as well as their possible demands of developing them. Relying on a representative questionnaire survey conducted in Hungary in March and April 2020, the data were examined by a machine learning and correlations to identify the factors, attitudes and demands that influence the use of mobile devices during frequent commuting. The paper argues that the regularity of commuting in rural areas, as well as the higher levels of qualification and employment status in cities show a more positive, technophile attitude to new ICT and mobile technologies that strengthen the demands for digital development, with special regard to optimising e-government applications for certain types of commuting groups. One of the main limitations of this study is that results suggest a picture of the commuters in a narrow timeframe. The findings suggest that developing e-government applications is necessary and desirable from both of the supply and demand sides. Based on prior scholarly knowledge, no research has ever analysed these correlations in Hungary where commuters are among the European citizens who spend extensive time with commuting.
