Innovation, ownership and profitability

Research output: Contribution to journalArticlepeer-review


This paper considers the relationship between innovation, ownership and profitability for a panel of manufacturing plants in Ireland and Northern Ireland. Previous literature suggests that innovators are persistently more profitable than non-innovators, but little is known about how this link is moderated by external versus domestic ownership. We consider the link between innovation and profits separately for indigenous innovators and non-innovators and externally-owned plants. We also consider the determinants of innovation over the distribution of plant-level profitability, and find that the determinants of profitability – including innovation and external ownership – vary over the distribution from low to high profitability plants. We find support for the view that innovators and non-innovators have different profitability determinants, and that the profitability of externally-owned plants depends on very different factors to those of indigenously-owned enterprises.
