The most famous university rankings, mostly rank research quality and impact. However, they also don't take into account research institutes which makes no sense, if you ask me.

In most of Europe, the best research is done on research institiues such as German Max Planck, Frauenhofer, Leibniz and Helmholtz. French CNRS is highly respected world research institution and also not taken into account on rankings. There are also great government funded and private research institues in USA and China in addition to their great universities. For example, US department of energy, Argonne national laboratory or Chinese academy of science. They're all academic institutions which publish and have research impact. They should be taken into account.

Because there is a complex relationship between universities and research institutes, I think it's best to rank academic success of a country as a whole. Every country has a different educational system, organization and government.

In Germany, it's impossible to separate great research impact of Max Planck institute from german universities. They should be taken into account as a whole when their academic success is measured and quantified.

Do such national rankings exist?
