Larger firms (55%) are more likely to be partnering for innovation than smaller firms (36%), while the same holds for exporters (58%) and cross-border traders (53%) compared to domestic firms (31%). Exporters have a systematically higher rating in all kinds of business innovation attributes than cross-border traders, while the latter display higher ratings than domestic firms. These relationships are focused heavily on clients/customers and suppliers, with collaboration generally much less widespread for other partners. Overall, international partnerships are more widely reported than cross-border relationships for links with suppliers, higher education institutes, intermediaries and business services.
