The Effects of International Patenting On Export: Evidence From China

Activity: Talks or PresentationsOther Invited Talks or Presentations


This paper studies how international patenting affects the Chinese firm export performance during 2000-2016. Based on 289,416 international patents, we map them to domestic patented exporting firms. We find that international patenting promotes firms' exports. Furthermore, we leverage our detailed micro data on export and patenting activities at the firm-country-product level for those international patenting firms. First, we examine the heterogeneous effects of three types of patent application outcomes: successful application, unsuccessful application, and pending application, and find that their effects on export are all positive except the case of unsuccessful application. Second, we evaluate the spillover effect. We find that international patenting has within-product across-country spillover effect but no within-country across-product spillover effect. These effects help us to further explore the role of international patent applications in promoting exports, whether it is signal or protection.
