  Literature about the scholarly impact of scientific research offers very few
contributions on private sector research, and the comparison with public
sector. In this work, we try to fill this gap examining the citation-based
impact of Italian 2010-2017 publications distinguishing authorship by the
private sector from the public sector. In particular, we investigate the
relation between different forms of collaboration and impact: how intra-sector
private publications compare to public, and how private-public joint
publications compare to intra-sector extramural collaborations. Finally, we
assess the different effect of international collaboration on private and
public research impact, and whether there occur differences across research
fields.
