  Investigations of the energy spectrum as well as the mass composition of
cosmic rays in the energy range of PeVto EeV are important for understanding
both, the origin of the galactic and the extragalactic cosmic rays. Recently,
three modern experimental installations (KASCADE-Grande, IceTop, Tunka-133),
dedicated to investigate this primary energy range, have published new results
on the all-particle energy spectrum. In this short review these results are
presented and the similarities and differences discussed. In addition, the
effects of using different hadronic interaction models for interpreting the
measured air-shower data will be examined. Finally, a brief discussion on the
question if the present results are in agreement or in contradiction with
astrophysical models for the transition from galactic to 10 pagesextragalactic
origin of cosmic rays completes this paper.
