R&D subsidies designed to encourage innovation efforts by firms may have intended and unintended effects on the way they organize their innovation process.We present empirical evidence on how R&D subsidies affect firms’ R&D cooperation strategies.In particular,we investigate whether receiving public R&D subsidies affect the probability that a firm will set up an R&D partnership with a public research organization (PRO),or with other firms.Our main findings are:(i) public support significantly increases the chances that a firm will cooperate with a PRO,and (ii) public support also increases the likelihood that a firm will establish private partnerships,but to a smaller extent and only when firms have intangible knowledge assets.These results suggest that public R&D programmes trigger a behavioural change in firms’ R&D partnerships,alleviating barriers to cooperation.
