The note presents the computation of industry foreign inputs dependency using input-output tables. It gives details on each level of dependency and finish with the infinite computation using the Leontief inverse matrix. It ends with some evidence by using WIOT data from 2000 to 2014 which shows the high growth of the technical dependency to Chinese inputs over the past 15 years. Construction, Telecommunications and Chemicals are Chinese-dependent sectors among the 20 first which also contribute a lot to the French economy. Nevertheless, for France and European countries, the dependency to Chinese inputs is well behind the dependency to European inputs.
