French to English Bus/Financial Government / Politics

This is, in context, more or less synonymous with 'shareholder capitalism': the context is as follows:

"La concentration du capital et du pouvoir décisionnel aux mains des investisseurs institutionnels – des gérants de fonds supposés organisés et professionnels – modifie considérablement la donne. Ces derniers seraient, en effet, en mesure de peser sur le management des entreprises, ou du moins, de surveiller de manière plus étroite les décisions des managers. Certains qualifient cette nouvelle configuration de **capitalisme actionnarial ou patrimonial**"

I have seen this translated as 'patrimonial capitalism' but this sounds like translationese to me, and an online search reveals all references to this term come from translated sources. I think in context, 'asset-based capitalism' is what's meant but it's not very snappy. 'Proprietary capitalism' seems tempting, but this actually means the opposite: the control of the company by the proprietors (rather than shareholders).

Any ideas and insights gratefully received.
