本研究提出了一种新的渠道，通过贸易自由化可以通过减少目的市场的贸易政策不确定性（TPU）来诱导创新。为了验证这种联系，我们利用2001年中国加入世界贸易组织（WTO）所产生的TPU显著降低作为准自然实验。我们发现TPU的降低显著地鼓励了企业的专利申请：在中国加入WTO后，不确定性降低幅度较大的行业的企业提交了更多的发明专利申请。我们还发现，企业对TPU降低的创新反应因生产率、所有权、出口地位和投资的不可逆性而异。(c) 2020 Elsevier B.V.版权所有
This study proposes a novel channel through which trade liberalization may induce innovation through the reduction of trade policy uncertainties (TPU) in destination markets. To verify this linkage, we utilize the significant reduction of TPU engendered by China's accession to the World Trade Organization (WTO) in 2001 as a quasi-natural experiment. We find that reduction in TPU significantly encourages firms' patent application: firms in sectors with a larger reduction in uncertainty filed more invention patent applications after China's WTO accession. We also find that firms' innovation responses to TPU reduction vary by productivity, ownership, exporting status, and the irreversibility of investment. (c) 2020 Elsevier B.V. All rights reserved.
