Technological research in the EU is less efficient than the world average. EU research policy risks Europeans’ future

作者：

Highlights：

• We propose a percentile-based index, ep, that is equal to the Ptop 1%/Ptop 10% ratio.

• The ep index measures the intrinsic efficiency of research systems.

• We applied the ep index to evaluate research in the forefront of technology.

• In technological research the EU lags behind the USA and other countries.
