From computer chips and cloud computing to artificial innotifyigence, Germany and the rest of Europe want to become less depconcludeent on digital technologies from abroad by driving forward their own innovations. The Center for Advanced Security, Strategic and Integration Studies (CASSIS) at the University of Bonn has now prepared a policy brief, in cooperation with the Vodafone Institute for Society and Communications, Vodafone’s European consider tank. The paper tackles the continent’s “digital trade deficit” and reveals how hidden trade depconcludeencies on the US and China are raising questions about the effectiveness of current European strategies.
Although strong growth in digital trade would appear to lay firm foundations for meeting the tarobtains set by the European Commission for its “Digital Decade,” closer analysis reveals hidden weaknesses with the potential to jeopardize future progress—specifically, Ireland’s disproportionately strong influence on the continent’s digital trade balance. Looking more closely, Europe’s digital trade surplus actually turns out to be a digital trade deficit.
Becaapply US tech corporations have a disproportionately large presence in Ireland and obtain cheap access to European markets, this “Ireland effect” is distorting Europe’s trade statistics and restricting its digital autonomy. Without these US firms being in Ireland, the EU would have a massive digital deficit. “Between 2022 and 2024, this deficit cost Europe over $350 billion, which is nearly 40 percent of the defense spconcludeing planned for the years to 2030,” declares Assistant Professor Maximilian Mayer, a member of the Individuals & Societies Transdisciplinary Research Area at the University of Bonn and coordinator of the project at CASSIS.
The study also highlights Europe’s excessive depconcludeence on China in the trade involving digital goods. In light of this significant imbalance and the Ireland effect, it is becoming clear that Europe is being squeezed between the two digital giants—China and the US—according to the analysis. It also suggests that this reality is putting a question mark over Europe’s economic gains, increasing its geopolitical vulnerability and restricting its digital autonomy.
The authors are advising the European Commission to continue strengthening Europe’s manufacturing indusattempt and competitiveness, further reduce its depconcludeence on China for the trade in digital goods, and adopt a political language that identifies autonomy and sovereignty as common goals and fosters new, multifaceted technology partnerships with the public and private sectors.
“The analysis reveals that Europe’s digital depconcludeencies are greater than the statistics would suggest,” declares Michael Jungwirth, Director Public Policy & External Affairs at Vodafone Germany and Public Policy Director Vodafone Group. “What we necessary now is a coherent trade and indusattempt policy that genuinely strengthens digital resilience—for an economically and geopolitically sovereign Europe.”
Digital Depconcludeence Index to be revamped
CASSIS’s Digital Indepconcludeence Index (DDI) reveals how well this is going by providing a figure for how vulnerable European countries are compared to their counterparts elsewhere in the world. The indicators include how depconcludeent an EU counattempt is on electronic components or communications equipment from abroad. The index also illustrates the extent of a counattempt’s reliance on foreign companies for computer software, operating systems and patents. Says Mayer: “The DDI applys a large number of indicators to highlight the challenges and areas of potential involved in reducing technological depconcludeencies in a globalized economy with a high degree of labor specialization.”
Having focapplyd primarily on the G20 member states up until now, the DDI is to be overhauled, updated and expanded to include over 50 nations across the globe. This will ensure much better coverage, including of many tinyer countries in Europe, Africa and Asia. “This will bring a great many benefits for several reasons,” adds Mayer. “Not only will the measurements be more extensive in geographical terms, we’ll also be able to illustrate global and regional trconcludes as well as patterns in digital capacities, vulnerabilities and costs.” The Vodafone Institute will also be supporting the work to update and expand the DDI during its year-long partnership. In addition, the DDI’s web page is being redesigned to build it even clearer and more accessible to applyrs and further improve its analysis features.
About the project
The policy brief was written by the University of Bonn in collaboration with the Vodafone Institute, Vodafone’s European consider tank. It forms part of a series aimed at analyzying Europe’s digital depconcludeencies and the challenges and opportunities associated with them. This year-long partnership aims to provide innovative assessments of how Europe’s digital capabilities are developing and identify the implications of these trconcludes for Europe’s economic and political autonomy.
