The introduction of digital technologies affects most socio-economic processes and activities in the economy, from agriculture to public services. Even though the world is currently only in the early stages of digital transformation, the digital economy is growing rapidly, especially in developing countries. Shortly, digital platforms will be able to replace the "invisible hand" of the market and turn it into digital. Some digital platforms have already reached global reach in some sectors of the economy. The growing value of data and artificial intelligence is reflected in the high capitalization of these enterprises. Their growing role has far-reaching consequences for the organization of economic activity and integration into the field of e-business. However, their importance and level of development in different countries differ significantly. The main purpose of this article is an assessment of the level and trends of the digital economy in the world and the identification of homogeneous groups of states following the main trends in the development of its components from among the EU countries. The methodology of the conducted research is based on the use of general scientific research methods in the analysis of secondary sources and the application of statistical methods of correlation-regression and cluster analysis. Macroeconomic indicators and components of DESI (Digital Economy and Society Index) were used for the analysis. Results. Based on the analysis established that most developed countries have a medium level of digitalization of the business environment and a high level of digitalization of socially oriented public services, while countries with lower GDP focus their policies on building digital infrastructure and training qualified personnel.

국제주의 질서나 지역주의 및 쌍무주의 질서가 일응 무역자유화를 지향하는 점에서 양자는 일치하면서도 후자가 역내 자유주의와 역외 보호주의라는 양면성을 가지므로 갈등과 모순이 있을 수 밖에 없다. 그러나 차선 이론이나 GATT나 WTO의 현실인정의 예외 규정으로 보완내지 공존관계에 있음이 현실이고 나아가 지역주의와 쌍무주의가 국제주의의 실험장이 될 수도 있다. 우리나라의 통상현안과 관련하여 볼 때 WTO출범에도 불구하고 이처럼 국제주의질서와는 별개로 지역주의 및 쌍무주의 질서가 현실적으로 공존함으로써 우리의 어려운 통상환경의요인으로 작용하고 있으므로 대국적인 통상정책으로 이에의 적절한 대응이 요구된다. 요컨데 우리경제가 OECD에 가입했고 선진경제대열에 진입하고 있음을 감안할 때 범세계적 시각에서 통상관련제도를 국제주의 질서의 측면에서 최대한 개편 보강하여 통상협력 하는 한편, 지역주의나 쌍무주의 측면에서도 권역별로 충화된 수단의 최적 Mix를 도출함으로서 조화로운 통상관계를 정립시켜 나가야 할 것이다.
