摘   要：China's overseas patents grew explosively recently. This paper studies how patenting overseas affect firms' exports. We study this question by merging patent data from European Patent Office and China's firm-level exports data. It is found that exports in value are positively affected by the number of effective patents in export markets of the exporter. However, this positive effect mainly comes from the increase in export quantity rather than higher prices, which is inconsistent with the high monopolist profits predicted by the traditional market power effect. This puzzling finding could be explained by Bertrand Competition Model which relies on an important feature of Chinese overseas patents—a majority of patents belong to information and communication technology sectors. It is also found that export prices dropped as patents expire in the export markets. We also present the impact of patenting identified by time-variation for each firm within its product-country markets. Overall, we find firm's heterogeneity at product level, particularly its time variation, plays an important role on the relationship between patents and exports.
