i6eal Research Notes turn our longitudinal public-source data into tightly bounded empirical studies. Every issue publishes its definitions, limitations, sources and a frozen analysis table.
The note compares enterprise AI use in Germany with the EU-27 aggregate in 2025. Germany records 25.97% versus 19.95% and ranks eighth among member states, but the difference varies materially by firm size and economic activity. The analysis is descriptive and makes no causal claims.
Not every tool becomes a Research Note. The series only includes work with an economic or digital-policy research question and reproducible evidence.
A frozen analysis table remains permanently available with the PDF.
No causal claim where the source only supports a comparison.
Original units, denominators, status flags and method breaks stay visible.
PDF, metadata, BibTeX and RIS are available without registration.
