Wefind that reduc-tion in TPU significantly encouragesfirms’patent application:firms in sectors with a larger re-duction in uncertaintyfiled more invention patent applications after China’s WTO accession.We alsofind thatfirms’innovation responses to TPU reduction vary by productivity, owner-ship, exporting status, and the irreversibility of investment.
