Data and code for: Opposing firm-level responses to the China shock: output competition versus input supply

We decompose the ``China shock'' into two components that induce differentadjustments for firms exposed to Chinese exports: an output shockaffecting firms selling goods that compete with similar imported Chinesegoods, and an input supply shock affecting firms using inputssimilar to the imported Chinese goods. Combining French accounting, customs,and patent information at the firm-level, we show that the output shock isdetrimental to firms' sales, employment, and innovation. Moreover, thisnegative impact is concentrated on low-productivity firms. By contrast, wefind a positive effect - although often not significant - of the inputsupply shock on firms' sales, employment and innovation.<br>
