DESCRIPTION:We study how imported input price shocks affect both the intens
 ity and direction of innovation. Using comprehensive French firm-level data
  combining accounting records\, ownership structures\, customs transactions
  and patents over the period2014-2023\, we construct firm-level exposure to
  input price shocks based on structural breaks in product-level import unit
  values from non-EU countries\, aggregated using a shift-share design. Inno
 vation intensity is measured using priority patent applications\, while the
  direction of innovation is characterized by mapping patents to products an
 d embedding them in a production network to distinguish innovations directl
 y related to affected inputs from those connected through upstream\, downst
 ream\, or technologically adjacent linkages. We find that input price shock
 s primarily affect the direction rather than the level of innovation. Expos
 ed firms reallocate innovative activity toward connected technological doma
 ins\, consistent with network-based directed technological change. This rea
 llocation is strongest among firms at the technological frontier\, while sm
 aller and less productive firms adjust more through overall innovation inte
 nsity. We provide evidence for specific industries\, showing that the shock
 -innovation impact-response is heterogeneous. We interpret our results as f
 irms’ resorting to what we label defensive innovation. Our findings can i
 nform policy making and firm strategy in a context of increasing trade frag
 mentation and geopolitical risk.\\n\\nContact: Sullivan Hué - sullivan.hue
