논문 초록
: We study how competition drives firms to use different types of innovation and affects the aggregate economy through changes in innovation composition. We build an endogenous growth model in which multi-product firms improve their own products through internal innovation while entering others’ markets through external innovation, subject to a novel friction “imperfect technology spillovers.” If learning others’ technology takes time due to the friction, firms with technological advantages increase internal innovation to protect their markets from competitors (“market-protection effect”), leading to a decline in external innovation (“technological barrier effect”). Using the administrative data of the U.S. patenting firms, we find consistent regression results. The changes in innovation composition matter for the aggregate implications of competition, given the distinct roles of the two innovations in aggregate outcomes.
