本研究分析中美貿易對廠商帶來的影響，使用 1991 年到 2015 年美國製造業廠商層級資料來分析中國進口競爭帶來的影響，結果顯示中國進口滲透增加對美國廠商定價能力帶來顯著負面影響，對廠商 Tobin’s q 與新穎組合指標比率 (Novelty in Recombination Ratio, NR Ratio)沒有顯著影響，但對廠商創新、廠商新穎技術起源指標比率(Novel Technological Origins Ratio, NTO Ratio)與新穎科學起源指標比率(Novel Scientific Origins Ratio, NSO Ratio)帶來顯著正向影響。當廠商屬於創新型廠商時，他可以抵抗部分對定價能力的負面影響，同時加強對創新帶來的正面影響。總結來說中國進口滲透增加有促進競爭(pro-competitive)的效果，且廠商更有意願投入創新來逃離競爭。

This article investigates the effect of Chinese import competition using U.S. manufacturing firm-level data from 1991 to 2015. The results indicate that increased Chinese import penetration has a significant negative effect on firms' markups. It does not have a significant effect on firms' Tobin's q or the Novelty in Recombination Ratio (NR Ratio). However, it has a significant positive effect on firms' innovation, the Novel Technological Origins Ratio (NTO Ratio), and the Novel Scientific Origins Ratio (NSO Ratio). Innovative firms can mitigate the negative effects on markups and enhance the positive effects on innovation. In summary, increased Chinese import penetration has a pro-competitive effect, encouraging firms to invest more in innovation to escape competition.
