This paper examines the impact of digital communication technologies on economic interdependence between China and the European Union. Drawing on a global communication theoretical framework, the study argues that information flows, digital platforms, and communication infrastructures play a crucial role in facilitating cross-border economic activities. By reducing transaction costs, improving market accessibility, and accelerating the exchange of information, digital communication technologies contribute to the expansion of trade and investment relations between the two economies. At the same time, the study recognizes that economic integration in the digital era is influenced not only by technological developments but also by institutional and regulatory factors. Differences in data governance frameworks, privacy regulations, and digital policies between China and the European Union may create barriers to information exchange and limit the potential benefits of digital connectivity. Accordingly, the research hypothesizes that increased digital communication connectivity strengthens economic interdependence, while greater regulatory divergence constrains the growth of digital economic cooperation. Using a mixed-method approach that combines quantitative trade indicators with qualitative analysis of digital governance frameworks, this study seeks to explore the relationship between technological integration and institutional constraints. The findings are expected to demonstrate that digital communication technologies have become an important driver of China–EU economic interdependence, but their impact remains conditioned by differences in regulatory and governance structures.
