内容简介:

This study examines how ride-hailing services affect localized knowledge flows among firms. Leveraging the staggered entry of Uber and Lyft across U.S. counties, we construct a panel dataset of within-city patent citations to measure interfirm knowledge flows. Using a difference-in-differences design, we find that the entry of ride-hailing services significantly increases local knowledge flows. Mechanism analyses using county-level traffic data and micro-level mobility data suggest that this effect operates through improved urban mobility: the entry of ride-hailing increases local traffic flows and facilitates opportunities for interactions across organizational boundaries. Consistent with this mechanism, we observe that the effect is stronger for firms that experience greater travel-time savings when using car-based transportation. Additional analyses show that ride-hailing entry disproportionately benefits firms with lower prior innovation output and fosters collaborative innovation. Overall, our findings indicate that, unlike physical infrastructure that creates new transportation links or relocates firms, ride-hailing platforms foster localized knowledge exchange and innovation by improving the use of existing urban transportation networks and enabling interpersonal interactions among geographically separated firms.
