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 period 2014-2023\, we construct firm-level exposure t
 o input price shocks based on structural breaks in product-level import uni
 t values from non-EU countries\, aggregated using a shift-share design. Inn
 ovation intensity is measured using priority patent applications\, while th
 e direction of innovation is characterized by mapping patents to products a
 nd embedding them in a production network to distinguish innovations direct
 ly related to affected inputs from those connected through upstream\, downs
 tream\, or technologically adjacent linkages. We find that input price shoc
 ks primarily affect the direction rather than the level of innovation. Expo
 sed firms reallocate innovative activity toward connected technological dom
 ains\, consistent with network-based directed technological change. This re
 allocation is strongest among firms at the technological frontier\, while s
 maller and less productive firms adjust more through overall innovation int
 ensity. We provide evidence for specific industries\, showing that the shoc
 k-innovation impact-response is heterogeneous. We interpret our results as 
 firms’ resorting to what we label defensive innovation. Our findings can 
 inform policy making and firm strategy in a context of increasing trade fra
 gmentation and geopolitical risk.\\n\\nContact: Sullivan Hué - sullivan.hu
