Academia is more concerned with the volume of publications rather than impact and unique ideas.
As a generalization, this is false. Certainly there is more emphasis on publication than is warranted, but most of the top places care much more about impact/reputation than about raw # of papers or citations. If you talk to people about how research labs hire newly-minted PhDs, how faculty are hired, or how tenure decisions are made, everything I've heard suggests that, at least for good places, they aren't just looking at the length of your pub list or the # of citations.
